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.
