Sealing tile grout is necessary for protecting it from stains, bacteria, mold, and mildew. But how long will one application of grout sealer last?

Grout sealer should be reapplied routinely. Tile sealers will last one year in areas of heavy use or traffic, even if the sealer claims to be long-lasting. Meanwhile, parts of the tile that aren’t exposed to much traffic can last for up to 2 years.

How Long Does Tile Grout Sealer Last?

Knowing how long tile sealer lasts will help you determine the best time to reapply them.

One application of tile grout sealer will last around a year in areas that are exposed to heavy traffic. However, sealed tile and other areas that aren’t exposed to as much traffic can last up to 2 years.

The most efficient way to tell if it’s time to reseal your grout is to pour a few drops of water on the tiles and the grout lines. If the water is absorbed by the grout and no beading occurs, it’s time to reseal. On the other hand, if the water beads up on the surface, then the sealer is still active.


Depending on the traffic tile grout is exposed to, sealer can last one up to two years. You can use the water beading test to accurately determine if it’s time to reseal or not.
