Grout is a fantastic material that is ultimately used to fill the gaps between tiles. Naturally, being typically used for bathroom tiles, it is not surprising to wonder: is grout waterproof?

In this short guide, we will explore this question as well as provide an answer, and suitable recommendations. Let’s get into it!

So… Is Grout Waterproof?

The quick answer to this question is no it is not! Grout itself is a porous material, meaning it has minute holes that water (and air) can pass through and be absorbed.

In order to answer this question properly, we need to first understand what exactly waterproof means.

What does Waterproof Grout mean?

Waterproof itself means “impervious to water”. In simple terms, this means that it does not allow water to go through.

Grout is described as a porous (has tiny holes) material, typically used to seal joints between tiles and therefore by definition is not waterproof.

For most grout, especially bathroom or shower grout, you will need to “seal” these holes with grout sealer. Grout sealer is usually a clear, water-based, liquid that fills the pores between the grout, to preserve it as well as make it water-repellant – but not waterproof.

Do I need grout sealer?

This all depends on what type of material you used for your tiles lines. Although the name used to describe tile lines is grout, quite often grout is not the material that has been used. Also, if you used a grout pen, some of them are similar to grout sealers in that they make the grout water resistant.

There are a number of different products or materials as grout, these include:

• Grout
• Caulk
• Sealant
• Epoxy
• Cement

Grout and sealant are quite commonly used for grouting. Sealant itself is quite a popular choice in a shower because it is usually waterproof and has a whole heap of other features, that make it more favourable than grout.

Which types of grout are waterproof?

Below is a table that outlines which types of grout are waterproof and which are not:

What is the difference between waterproof and water-resistant?

As discussed earlier, waterproof essentially means not allowing water in. Water-resistant on the other hand means the water is able to penetrate to some degree but not totally.

Grout sealer and grout pens are great for preserving grout, making it look newer and also making it water resistant. Because of its nature, you would need to keep reapplying it every so often to renew the water-resistance effect.

Ultimately, if you apply lots of coats to your grout, water protection will be much greater but you still cannot guarantee that it will become waterproof.

In addition, some grout pens prevent mould, waterproof the grout and prevent further staining from occurring, making them a fantastic investment.

Are grout pens easy to use?

Grout pens are super easy to use. Most, if not all of them, are ready to use right out of the box. Simply remove the lid and apply to your grout lines. As they are in the shape of a marker pen it is like we are drawing or writing so it feels very familiar in your hand.

How long do grout pens take to dry?

Most Grout pens are touch dry in around 30-60 minutes or so. It is best to leave to dry for at least an hour or so before you apply the next coat just to ensure that the grout pen’s coating has totally dried.

It’s a well-known fact that grout is the unsung hero of the tile world. It can make or break your wall, countertop or floor, so it’s important to keep an eye on how dirty and damaged it gets over time.

A good grout sealer can help combat this issue by providing a protective layer between dirt and grime and your tiles, preventing any further damage from occurring.

This article will go through our top 6 best grout sealers in 2025 for you to choose from!

This grout sealer is made from oil paint that dries on top of the grout, leaving a strong, impenetrable, yet smooth layer.

The bottle comes with its own ergonomically designed sealer applicator or pipette, making the process more streamlined and reducing any mess. After application, it’s recommended that you leave to dry fully for around 24 hours for wall tiles, and roughly 36-48 hours for floor tiles. Following this, surfaces can then be cleaned in the usual way afterwards.

• Suitable for both wall and floor grout
• Overspray dries invisible

3) LTP Mattstone Grout Sealer

It provides a natural matte finish that allows surfaces to breathe, with minimal change to the surface character. This sealer is suitable for both interior and exterior use.

It can be used in wet areas, and on a variety of surfaces including slate, sandstone, terracotta, unpolished marble, travertine, and cement. Once applied, it dries after approximately 2 hours, but takes a further three days to become fully resistant to water, oil, and grease.

Key Features

• Repels water, oil and grease
• Provides a natural, matt finish and enhances the colour and texture of the tile
• Suitable for internal and external use.
• For use on travertine, stone, sandstone, slate, marble, terracotta, quarry tiles, brick and paving

Whilst it’s ideal for any bathroom or kitchen, it’s perfectly suitable for use on any surface with tiles and grout – especially wet rooms and shower enclosures. Once applied, it seals grouted areas with long-lasting protection against water, dirt, oil, grease, and limescale, and makes these surfaces easier to keep clean.

It’s ideal for cementitious grouts, as it prevents water and stains from being absorbed into the surface of the grout. It’s more environmentally friendly than other grout sealers on the market; it’s made from a type of VOC-free, water-based technology that makes the product less taxing on the environment, without compromising on its effectiveness.

The spray comes ready to use, is easy to apply, prevents water and stain penetration, and doesn’t alter the colour of the grouting once applied. As it’s a water-based product, it allows for longer time gaps between treatments.

Key Features

• Protects and sanitizes grout joints
• Prevents water and stains from being absorbed into the surface
• Ready to use and easy to apply

6) Black Diamond Stoneworks Ultimate Grout Sealer

Here is another water-based spray grout sealer that gives long-lasting protection and is easy to apply, simply by flipping up the top and pressing the spray handle. It gives off very little odour, penetrates porous grout deeply when applied, and also bonds with it chemically. This provides a long-lasting, invisible barrier that extends the life of your grout.

It is safe for use on any type of grout and can be used both indoors and outdoors. This spray is great for repelling water, food stains, grease, mould, mildew, and more. One of the best things about this product though is that it is completely colourless and protects the natural colour of the grout, rather than altering it like some other grout sealing products.

Key Features

• Easy to Apply
• Safe for white and coloured grout
• Protects against staining

Does grout sealer really work?

Yes, grout sealer can work very well. Applying a grout sealer product will protect your grout making it water-resistant as well as repelling germs and bacteria too. Sealing your grout also helps extend its life by maintaining its appearance, texture and consistency, so grout sealer really does work and you should plan on getting some.

What is the best way to seal grout?

We have actually made a guide on how to seal grout for your shower. Ultimately most products methods will vary to a degree, especially depending on the type of grout sealer you go for. Generally, however, sealing grout consists of cleaning and drying the grout surface, applying the grout sealer and waiting for it to dry.

Does tile grout need to be sealed?

If possible, it is recommended that you seal your grout immediately after installation. In addition, you should seal your grout once a year or so to ensure that it is protected, preserved and kept looking great. If you don’t seal your grout, its colour will fade quicker, it could let in moisture and bacteria and could lead to damage to the group as well as your tiles, so it is definitely a good idea to seal tile grout.

What is the best grout sealer to use in a shower?

Our best grout sealer pick was the HG Colourless Grout Sealer. It is colourless and resistant to water and dirt, making it perfect for sealing your shower grout.

What happens if grout sealer dries on tile?

Most grout sealer products are clear and colourless so you wouldn’t notice it very much if it dried on your tiles. However, if you have opted for a grout sealer that is not colourless when you are applying it ensure you keep a damp cloth nearby so that you can wipe the excess grout sealer off of your tiles.

How long does grout sealer last?

Most decent grout sealers should last around a year or so, which is why we recommend that you reseal your grout every year to ensure it is consistently protected. This will also make sure that your grout lasts for a long time and stays looking brand new.

Grout is a porous material that can be found in the spaces between tiles, and it’s typically used to fill these gaps.

If you’ve ever walked into someone else’s bathroom and noticed how dirty their grout has become, then you know how important this substance is for maintaining the cleanliness of your shower and bathroom.

Unfortunately (or fortunately), there are many different types of shower grouts on the market that vary in quality. That being said, here are the top 8 best shower grouts of 2025!

Our Best Shower Grout Picks

1) UniBond Anti-Mould White Waterproof Grout Sealant

This specially-formulated shower grout sealant – made with silicone acetoxy technology – is ideal for warm and humid environments such as bathrooms and kitchens, as well as other areas with tiled surfaces. Once dried, it forms a permanently flexible, mould-resistant, waterproof sealant. Additionally, it has a high adhesion level, ensuring the seal will stand the test of time.

With regular cleaning, you can make sure that grouted areas stay mould-free for good. This UniBond sealant is also very user-friendly; after applying it with a gun, the white silicone seal is ‘touch dry’ within just 20 minutes, and fully dry within 24 hours.

Key Features

• Great for use in warm, humid environments
• Long-lasting with high adhesion
• Touch dry in just 20 mins
• Fully dry in around 24 hours
• One cartridge lasts for 1 x bath, 2 x showers & 2 x sinks

2) UniBond RE-NEW One-Step Bathroom & Shower Grout

At number 2, we have the UniBond RE-NEW One-Step Bathroom & Shower Grout.

This innovative joint filler is great for refreshing old bathroom or shower grout. It can be applied straight on top of the old sealant – there’s no need to scrape away the old sealant or grout beforehand.

The self-tooling applicator ensures that applying the product is easy and provides a professional-looking finish, with no additional smoothing tools needed. It offers three-factor mould resistance by preventing, killing, and repelling mould over the long term.

Over time, it doesn’t yellow, shrink, or crack, and it dries in a shade of translucent white that makes it blend in seamlessly wherever it’s applied.

Key Features

• The Triple Protect mould resistance technology repels, kills & prevents mould
• Non-Slip formulation

• Suitable for interior walls of kitchens, bathrooms and power showers

What is the best grout to use in a shower?

We have found that the best grout to use in a shower is the UniBond Anti-Mould Waterproof Grout Sealant. This is because it is waterproof, has anti-mould properties, dries quickly, and is durable. These are all very important features that a good shower grout should have.

Is epoxy grout better than regular grout?

No, not necessarily. Epoxy grout is more durable than regular grout but the easy maintenance of grouted tiles should also be considered when making comparisons between epoxy and non-epoxy products. Conventional grouts are less expensive as well and, with proper care, perform just as well as epoxy for many applications.

Is grout waterproof in showers?

No, grout in the shower is usually not waterproof – depending on what you opt for. Additionally, it can get damaged if enough water has been absorbed into the surface of the grout or if there is excessive moisture on the surface that compromises its structural integrity. Over time, salt deposits from hard water and mineral deposits will also stain your grout making it look dull and unattractive, requiring light maintenance now and then to keep it looking fresh and clean. If you are buying a grout though be sure to check if it is waterproof.

How do you waterproof shower grout?

In order to waterproof shower grout, you will need to buy a grout sealer and some decent grout pens offer this feature. Before you waterproof your shower grout, you will need to clean, wipe and dry your existing shower grout to ensure the waterproofer can work effectively. Once you have done that, just follow the instructions on your chosen product. Typically you have to apply the waterproofer and leave it to dry for a specified period of time.

Is epoxy grout worth the money?

Epoxy grout is definitely worth the money. Unlike some regular shower grouts, epoxy grout won’t shrink, crack, or yellow/discolour, making it the perfect solution for application in wet areas, such as a shower or bathroom, for example. In addition, it is also resistant to harsh chemicals you’d find in most cleaning products.

Can I use caulk instead of grout in shower?

Caulk is a waterproof sealant or filler, typically used in building work, DIY and repairs. It is not a good idea to use caulk instead of grout in a shower because caulk can dry or shrink over time. This is why it is best to choose grout for your shower.

Do you need special grout for showers?

You don’t need a special grout for showers. Ultimately, as long as it meets your requirements it should be more than suitable. For me, I’d go for a shower grout that is inexpensive, has good reviews, waterproof and easy to apply.

What is the best grout cleaner?

All the grout cleaners on this list are more than suitable. We have found that the most popular product used to clean grout was HG’s Mould Spray because it was particularly effective at cleaning tile grout as well as removing stains and mould.

What do professionals use to clean grout?

Most local professionals will use similar products to those cited on this list. Bigger cleaning companies, however, will likely use lower quality products that are only available to businesses in wholesale quantities. This is because as they use so many cleaning products daily it becomes expensive to use premium products and therefore will need to save on cost.

How do I get my grout white again?

To get your grout white again you will need to use a powerful grout cleaner as well as a good grout cleaning brush. It is easier to maintain the whiteness of your grout if you clean it regularly, rather than trying to scrub it every year or so so try and get into the habit of cleaning it more often. If you find that even after cleaning your grout that it still isn’t white enough, you may need to get a grout whitening pen.

What is the easiest and fastest way to clean grout?

The easiest and fastest way to clean grout is to use a strong grout cleaning product, spray it on to your grout and let it sit for a while. This will let the product work and loosen the dirt, allowing you to scrub and rinse it away with ease. Some heavy duty grout cleaners will work faster but keep in mind they are quite potent and could damage your grout or tiles.

How do you clean badly stained grout?

Most, if not all, of the grout cleaners on this list, work to clean badly stained grout. Most of the time the cause of the badly stained grout is mould so it is best to opt for a product that combats mould as well.

Does toothpaste clean grout?

Surprisingly some toothpaste can clean grout. Though with that being said, toothpaste, of course, is not designed in the same way as grout cleaners. For example, some grout cleaners have anti-mould properties where toothpaste does not, so it is best to opt for a proper grout cleaner.

Does baking soda clean grout?

Baking soda (and water) is one of the best homemade cleaners you can use IF when you don’t have a decent cleaning product available. As mentioned above, it is best to opt for a grout cleaner where possible as they are specially formulated to combat dirty grout.

Can you use a wire brush on grout?

You can use a wire brush on grout but it is not recommended. Wire brushes are quite coarse and therefore may damage your grout or/and your tiles so be warned. Most grout brushes have been designed with this in mind and you will find that the bristles are made of a less coarse material like nylon.

Can you use a brass brush to clean grout?

Similarly, you can use a brass brush on grout but it is not recommended. Brass brushes are also quite coarse and therefore may damage your grout or/and your tiles so be warned.

Updated: 9th August 2023

Getting a good bathroom sealant is a crucial part of ensuring that your bathroom looks pristine, clean and is mould-free. Our bathrooms are exposed to mould on a daily basis because of our constant water usage; that’s why it is absolutely essential to use a sealant throughout your bathroom (on your sinks, baths, shower trays etc).

While caulking is a fairly popular method for sealing walls; it is not entirely waterproof. And it is for this reason that it would be best to use a silicone sealant in your bathroom. Now, choosing a suitable sealant can be difficult for those who have never done so before. Therefore, here are some of the best bathroom sealants that are available right now!

Our Best Bathroom Sealant Picks

1) UniBond Anti-Mould White Waterproof Sealant

Our best pick is the UniBond Anti-Mould White Quick Drying Waterproof sealant. It is perfect for those looking for a good sealant that will provide long-term protection. Its formula is ideal for those areas that are very warm and humid, like bathrooms and showers. What makes this product unique is its adhesion formula that helps create a long-lasting result.

Once your UniBond Anti-Mould is applied, it makes a flexible and waterproof seal, which will reduce the chances of the seal breaking, making this one of the best anti mould sealant options out there. What’s even better about it is that it is entirely user-friendly; once the sealant is applied (with a sealant gun), the silicone seal will be touch-dry in about 20 minutes and completely dry in 24 hours.

Key Features

• Great for use in warm, humid environments
• Long-lasting with high adhesion
• Touch dry in just 20 mins
• Fully dry in around 24 hours
• One cartridge lasts for 1 x bath, 2 x showers & 2 x sinks

2) Everbuild Everflex 500 Anti-Fungal Bathroom Silicone Sealant

In second place, we have the Everbuild Everflex silicone sealant. This product is perfect for showers and bathrooms, and with its fantastic fungicide formula, it will provide solid and long-lasting protection from mould on the sealant itself. The waterproof formula makes it perfect for baths, showers, and basins and in my opinion is one of the best silicone sealants available.

If you need a quick dry sealant, then the Everbuild Everflex sealant is ideal for you; in the first 10 minutes after application, you can notice a skin form; after about an hour, the product will be touch-dry and completely dry in 24 hours. What’s even better about this product is that it comes in five different colours.

Key Features

• Fungicide formula protects from mould
• Offers long-lasting protection
• Dries very quickly
• Available in five different colours

3) UniBond Triple Mould Protection Bathroom Sealant

The UniBond Triple Mould Protection Bathroom sealant formula kills, repels, and prevents mould growth wherever it is applied. This sealant is long-lasting; not only is it waterproof, but it also offers flexibility, being ideal for challenging surfaces. Just like most UniBond sealants, it is quick-drying; once applied, it will be touch-dry in 20 minutes and completely dry in 24 hours. This sealant is ideal for showers, bathrooms, baths, toilets, wet rooms and tiled areas (can be used for grouting).

Key Features

• Long-lasting with high adhesion
• Touch dry in just 20 mins
• Fully dry in around 24 hours
• Triple protection formula kills, repels, and prevents mould growth

4) Gorilla Clear Mould Resistant Bathroom & Shower Sealant

This Clear Mould Resistant Sealant by Gorilla is 100% waterproof and can be exposed to water even after 30 minutes after application. This is one of the fastest drying formulas on the market. Furthermore, this all-purpose sealant is perfect for wet and mouldy surfaces like baths, sinks, toilets, windows, doors, etc. The product has a shrink and crack-proof formula which prevents any mould growth from occurring. Many customers prefer the smaller size as most of the time sealant is only available in a big cartridge, so if you have a smaller job you will have to store or throw away the leftover sealant and gun. 

Key Features

• One of the quickest drying formulas available
• Suitable for touch-ups
• Comes with a reusable nozzle
• Last for a long time

5) UniBond Go Seal Anti-Mould Bathroom Sealant

The UniBond Go Seal is specially formulated for sanitary sealing tasks in warm and humid areas, like sinks, baths, basins, and showers. This product has high adhesion, which makes it a very strong and durable sealant. There’s no sealant gun required to use this product, and the precision nozzle also ensures a mess-free and smooth application. Just like all UniBond products, this one offers anti-mould protection, repelling, killing and preventing mould ensuring your bathroom remains in pristine condition for a long time.

Key Features

• Anti-mould sealant
• Ready-to-use design
• Handy Size
• No sealant gun required

6) 151 Clear Waterproof Silicone Sealant

Just like the sealant by Gorilla, the 151 Clear Waterproof Silicone Sealant is a fantastic option if you are looking for a product you can cover smaller areas with. If you need more of it you can order it in a pack of six for very cheap. This is an incredibly affordable product and doesn’t need a gun for application – it comes with a nozzle. This product is available in two different colours, clear and white. Many customers preferred the size for smaller tidy-up jobs and because it’s clear makes the finish look shiny and brand new.

Key Features

• Easy to apply
• Waterproof
• Great for smaller jobs
• Very inexpensive

7) Everbuild Showerproof Bathroom Silicone Sealant

With its powerful anti-fungal formula, Everbuild’s Showerproof sealant is excellent at protecting against the growth of bacteria, mildew, and mould that are usually found in wet and humid areas like our bathrooms. This product has a quick-drying formula; after application, the sealant seals in 15 minutes, and it will dry completely 24 hours after application at a depth of 2mm.

The product is available in two colours: white and clear. This product is perfect for baths, showers, basins, sinks, PVC trims, cladding, panels, etc. The Everbuild Showerproof silicone sealant has a long-lasting but flexible seal, which makes it perfect for the changing weights and temperatures bathroom appliances experience.

Key Features

• Quick-drying formula
• The anti-fungal formula prevents the growth of bacteria and mould
• Available in two different colours
• Very long-lasting

8) UniBond White Speed-Seal Bathroom Sealant

Last but certainly not least, we have the UniBond Speed-Seal sealant which has an amazing fast-drying effect; you reapply this sealant in just one hour. This unique formula makes it ideal for wet and humid areas such as bathrooms, showers, sinks, etc.

Like most bathroom sealants, it requires a sealant gun and can be exposed to water within just one hour after application. It will be thoroughly dried in around 24 hours. This product also creates a hygienic barrier, so you can rest assured that mould won’t be able to get through.

Key Features

• Fast drying
• The special formula creates a hygienic barrier
• Can be exposed to water after one hour
• Has a long-lasting effect

What is the best bathroom sealant?

After researching all the greatest bathroom sealants online, we have found that the best bathroom sealant was the UniBond Anti-Mould. This was because it was very popular online with over 14,000+ reviews, likely thanks to its anti-mould formula, high adhesion, quick-drying, as well as its ease of use. We looked at all the top retailers like Screwfix, Wilko, Toolstation, B&Q, Wickes, Homebase, etc to check their best shower sealer range and reviews.

Can you put new bathroom sealant over old sealant?

According to MyBuilder, it is recommended that you never apply a new sealant over an old one, as in most situations, the old sealant has split, or it’s fallen away, and therefore, the new sealant will not bond correctly to the original sealant. In addition, it will not look that great either, so best to remove the old sealant if possible – while also being careful not to damage the surrounding area.

How do I stop my bathroom sealant from leaking?

To prevent your sealant from leaking, make sure the area that you are applying the product to is dry and free of debris before application. Also, the old silicone sealant should be removed thoroughly before your next application, while also ensuring that you allow the sealant to properly dry before use (usually around 24 hours) otherwise it will not set correctly.

What is sanitary sealant?

A sanitary sealant is simply a sealant (whether shower or bathroom e.g.) that prevents water from entering, and typically also consists of fungicides, that will prevent fungus and bacterial growth in areas where the sealant is applied.

Does vinegar remove silicone sealant?

In some cases, rubbing vinegar over the silicone sealant might safely remove some of the silicone sealant away. This is because the vinegar works to soften the silicone enough so that it becomes easier to remove.

Does WD 40 remove silicone sealant?

WD40 is another product that surprising also works as a good silicone sealant remover, but it is essential that you remove all the WD40 from the surface where you plan on applying the silicone sealant afterwards because they react together.

How do you apply bathroom sealant?

To properly apply the bathroom sealant, you first need to cut the top of the sealant nozzle 2cm at a 45-degree angle to shape the silicone line. After that, run the silicone entirely on the surface; once the sealant is applied, wet your finger with a silicone wipe and run your finger over the applied area to create a smooth line.

Popular Sealant Gun FAQs

What is the best sealant gun?

After researching all the greatest sealant guns online, we have found the top sealant gun to be the Wolfcraft MG 200. This was because it was very popular online with over 10,000+ reviews, likely thanks to its affordable price, automatic drip-stop, and rotating sleeve. We looked at all the top retailers like Screwfix, B&Q, Wilko, Argos, Toolstation, Wickes, Amazon etc to check their caulking gun range and reviews.

What makes a good sealant gun?

Ultimately, we want a sealant gun that allows us to apply sealant or caulk with ease. Therefore, it needs to be powerful, yet simple to use, have some kind of anti-drip feature, a rotating barrel to allow you to go around bends and corners without interrupting your application, and a comfortable grip to reduce hand fatigue. 

Is a caulking gun the same as a sealant gun?

Caulking gun vs Sealant gun – are they the same? Yes, they are the same. Sometimes they are also known as skeleton guns, silicone guns, mastic guns, caulk guns etc. The reason they are all the same is that they are all contained in a cartridge. These guns simply force the sealant or caulk out of the cartridge. With that said, the main difference between sealant and caulk is elasticity. Sealant is usually more elastic and water-resistant as it contains silicone – which of course is more effective for a bathroom or shower application.

Does a good caulking gun make a difference?

Yes, a good caulking gun does make a difference. The cheaper models can give you cramp and hand fatigue after a short while using them, potentially putting you off DIY altogether! Also, a good caulking gun can mean your application is a lot more smooth and professional looking. The Ryobi ONE+ Caulking Gun is totally automatic and therefore will make the process of sealing your bathtub, for example, much more enjoyable and easier to do than manually using a poor-quality sealant gun.

What makes a sealant gun dripless?

Many of the top models on our list above contain an anti-drip function or release clip. In a nutshell, the way they work is that the sealant is neatly severed so that it does not produce any excess mess and therefore potentially mess up your handy work.

How do you put sealant into a gun?

With most sealant guns you simply clip the cartridge into it and it’s ready to go – providing you have cut open the cartridge seal. Models like the Wolfcraft Mechanical Sealant Gun are much easier to clip in as you simply push the cartridge into it.

Is a sealant gun necessary?

A sealant gun is totally necessary. Most sealants, due to their viscous nature, can only be used with a sealant gun. It simply isn’t possible to squeeze out the sealant with your bare hands! With that being said, there are many sealants that don’t require a gun on our best bathroom sealant guide.

What is Grout Sealer?

Grout sealer is a water-based product that you apply to your grout lines after they’ve been cleaned. It’s like paint for tile and makes your tiles look fresh again. Most of them come in clear, white or grey shades so they blend with most colours.

The sealer will fill the pores between the grout and make any stains or dirt easy to clean off. The best part about grout sealer is that it’s affordable and will last for a long time, even if you are using your shower or bathroom on a daily basis.

Why use Grout Sealer?

There are many reasons why you may choose to seal your grout. One of the main purposes is so that showers and baths don’t leave water stains on your grout lines, which usually happen when you’re cleaning with harsh chemicals or abrasive tools. It also helps if you like to keep your bathroom and showering area clean and fresh-smelling by keeping dirt, grime, and stains away.

Grout is porous so it’s inclined to absorb everyday dust or dirt which can lead to mould and mildew if left alone. Regular cleaning with a damp rag won’t cut it either because the mould spores will still remain on the surface of your grout and will eventually grow back. This is where sealing your grout comes in handy because it prevents the absorption of dirt and particles, which are a lot harder to wash away afterwards.

Do you always need Grout Sealer?

Yes, you need it, except when you happen to be using epoxy-based grout. Grout sealer is not needed with epoxy-based grout because this type of grout naturally sheds water (and any additives applied to the surface). Unfortunately, once grout is applied and dry it becomes especially susceptible to water and so will need a grout sealer to protect against it. Some products like grout pens often have a type of sealer in their formula. Also, grout is usually different to shower sealant (typically applied with a sealant gun), which does not typically require sealing.

How to check if you need Grout Sealer?

Older tile will occasionally need a new coat of grout sealer now and then. Naturally, floor tile that is in areas that are frequented (walked on, touched etc) more will need grout sealer applied more often than other types of tile applications, such as bathroom wall tile, for example.

An easy way to test if you need grout sealer is simple – sprinkle a few drops of water at various points around your wall or floor tiles. If any of these soak in these drops of water then the grout needs to be resealed right away. Alternatively, if the water stays on top of the grout then it is doing its job and does not need resealing.

Benefits of using Grout Sealer

1. Tiles stay cleaner for longer

This is one of the major benefits; tiles will be clean for longer and require less scrubbing to remove mould, dirt and stains. The sealer keeps the grout water-repellant and adds a barrier between tile/grout and dirt that makes it easier to clean. Grout is non-porous so most of the time you can just use a damp cloth or brush without having to resort to chemicals.

2. Increases the life of your grouted area

Sealing your grout will only add more years of life to your home as grout is one of the hardest-wearing parts of a home. A well-sealed floor or wall doesn’t get dirty, cracked or stained easily while sealed grout does not absorb water and prevents mould formation, therefore it protects the tile below it from wear and tear.

3. Keeps dirt out

Grouts are porous and can absorb liquids and get stained pretty easily. Grout sealer will stop all of that from happening as it is a barrier between the grout and any liquids or dirt.

4. Improves appearance

Sealed grout will prevent staining, discolouration, and improve the overall appearance of your shower wall or tiles. Stained grout makes it look dull and grimy while unsealed grout can be stained by any liquid that gets onto it, making your tiles look dull as well. A sealer can also be used to cover old unsightly stains that have accumulated in your grout. Grout sealer will not only cover up the stains but it will keep your tiles looking clean and new for many more years to come.

5. Reduces mould and mildew

Sealing the grout prevents mildew and mould from growing on it. Grout is a good habitat for mildew and moulds to grow in as it gets wet regularly, damp from the cleaning products you use on it. Mould can easily form if there’s no sealer on the grout.

6. Adds waterproof protection

One of the main reasons people buy grout sealer is for the waterproofing element. Without a sealant, dirt and water can seep into the grout lines between your tiles. Cracks frequently appear on your tiles and could force them to break at any time. Sealants help you to prolong your tile surface’s lifespan by minimising damage.

What type of Grout Sealer should I use?

The type of grout sealer you should use will depend upon the application and your requirements. For instance, the grout sealer you’d get for your kitchen countertop would be different to the grout sealer for your shower wall tiles, for example. Ultimately, you will want to opt for a grout sealant that; was developed by a reputable company, doesn’t change shape, and provides long-lasting protection (at least 20 years or so).

The grout in your shower or bathroom can be a breeding ground for mould, mildew and bacteria. It’s not uncommon to find soap scum on the floor of bathrooms with tile floors. The best way to keep them clean is by sealing the grout lines that surround tiles with sealant. This will protect against water damage and ensure that any dirt you might miss when cleaning gets washed away during showers. This article will show you step-by-step how to seal your grout so that it looks fresh and clean all year round.

Step by Step: How to Seal Grout in a Shower

We have put together this step-by-step guide on how to seal grout in your shower so that you will be able to do it yourself instead of forking out lots of money hiring a contractor or handyman to do it for you. The process of sealing grout is fairly straightforward once you understand the basics and you will be able to keep your shower grout looking fresh as well as prolonging the life of your shower tiles.

Things you will need

Below is a list of things you will need to seal grout in your shower. Not all of them may be required but it is still good practice to get them all, especially if it’s your first time sealing grout in your shower.

1. A decent grout sealer
2. Decent eye protection
3. Pair of cleaning gloves
4. A vapour mask
5. A damp cloth

1. Work in a safe and well-ventilated area

It is important that where you are working is a safe environment. This means clearing and tidying the area around your shower to avoid tripping or falling over. In addition, you need to make sure the environment is well-ventilated, so you can set up an extraction fan to draw out the vapours from grout sealer or crack open a window etc. Once you have done these things, you can put on your gear and you are ready to begin.

2. Apply the Shower Grout Sealer

Once you have sorted the area and put on your safety gear it is now time to apply the sealer. Depending on the type of sealer, it will advise on how to apply it on the back of the product or in the instruction manual. For example, if you are using a grout sealer in the form of a spray can it will advise that you hold the can a minimum of around 25cm or so away.

Alternatively, if you are using a cartridge to apply grout it will advise that you ensure the sealant touches both the joint and the tile. It all depends on the type of shower grout sealer you have so be sure to follow the instructions on the back. For any grout sealant you go for, it is important that you use a damp cloth to wipe away any excess sealant as you go.

3. Let the Shower Grout Sealer dry

Once you have applied the shower grout sealant, you will need to let it dry. Many products by UniBond for example are touch dry within just a few hours. This will of course vary between grout sealants so be sure to check.

4. Test the sealed area and apply a second coat

Once the first coat is dry, you need to test it by gently sprinkling water droplets onto the sealed area. If the water is absorbed for a minute or so, you will need to follow steps 2 and 3 again and apply a second coat.

Alternatively, if the water drops are not absorbed and “stand” on the grout, then you are ready to proceed to the next step.

5. Let dry for at least 24 hours

Once you are happy with your application of the shower grout and it has passed your testing, you will need to let it dry for at least 24 hours. Some products will advise that 4-8 hours but I have found that sometimes this is not the case. Allowing it to dry for 24 hours will allow the grout sealer enough time to set properly without any worry that it hasn’t dried properly yet.

Popular Frequently Asked Questions

Should you seal grout in a shower?

Yes, you should seal grout in a shower – but this depends on the grout you have in place. Sealing grout in a shower is usually carried out to add water resistance to the grout (because grout isn’t waterproof) as well as add a protective layer to prolong its life and keep it looking fresh. With that said, some grout has waterproofing properties that may not require you to seal it. However, even in these instances, it doesn’t hurt to add yet another protective coat to your existing shower grout.

What happens if you don’t seal grout in shower?

If you don’t seal the grout in your shower, dirt, bacteria and water can seep into it. This can lead to cracks and damage on your tiles, leading them to eventually crumbling and breaking. In addition, if you don’t seal the grout in your shower, it can become discoloured and unsightly over time. By sealing your grout, you add a protective coat to it which prolongs the life of your shower tiles, minimises potential damage and keeps it looking new and fresh.

How often should you reseal the grout in your shower?

You should reseal the grout in your shower at least every year or so. Although many sealers will say they last for several years, it is good practice to reseal it now and then. This way you know that your shower grout always has a good level of protection and will continue to last for a long time.

Does sealing grout make it waterproof?

This depends on the grout sealer you buy but no; typically most grout sealers make grout water resistant – not waterproof. However, over time the initial coat of sealer applied becomes less effective and therefore will need occasional resealing to renew the waterproofing element.
