How Many Coats of Grout Sealer Should Be Used on Tile Walls?


One Coat Is Plenty

  • Most grout sealants on the market require only one coat for adequate protection. What you may want to consider is what sort of sealer you use. Depending upon the use of the space in which you have tile, you may do better to use a sealer that absorbs versus one that just coats. The type of grout you use will also help determine this. Doing your research before you lay the tile will benefit you and your design.

The More Coats the Better

  • For many people, if one of something is good then more of that something is better. Some people apply that theory to grout sealing as well. Using more than one coat of sealant will likely do no harm, especially if you are uncertain if you adequately sealed each grout line. It will, however, require more sealing product and cost more money.

Bottom Line

  • The most important rule when sealing your grout is to follow the manufacturer's directions. Each sealer has different qualities. Following the instructions given on the package will ensure you are using that product in the best way possible. After sealing the grout, be certain to reseal every year or two to ensure that you don't lose the protection and all of your hard work.
