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.
