What is a Grout Sealer?

Before we get into how to make grout waterproof, it’s important we define the term grout sealer since it plays a major role in making your grout waterproof.

A grout sealer is a liquid used to prevent moisture from entering the grout areas beneath your tiles.

Moisture can fill up the gaps between tiles, preventing them from being bonded for extended periods, and using a grout sealer beforehand helps keep all liquids and moisture away for the longest period.

How to Make Grout Waterproof

As mentioned above, a grout sealer is an important component of the tiling installation process because it prevents water from seeping into the grout and under the tiles.

Most grout is essentially formed of sand, and once dry, and in place between the tiles, it is ready to absorb water.

Grout sealant can be put on the grout to prevent it from absorbing water. It can be applied in three different ways. They are as follows

1. Using a brush to apply the product would be easier

When it comes to applying grout sealer, brushes are usually the first thing that comes to mind. Despite their ease of availability, many tilers find brushes difficult to use when applying grout sealer due to issues with the solution running off the tip.

2. Rolling on the Grout Sealer

Rolling is an easy way to apply grout sealer. Roll in a downward motion and be sure to stay close to the seam. Many tilers prefer rollers to brushes.

3. Spraying on the grout sealer

While spraying appears to be the quickest way to apply grout sealer (the spray, in theory, should not seep into the tiles, only the grout), you will need to clean the tiles later to ensure there is no residue on your tiles.
