how to apply grout sealer

To apply grout sealer, follow these steps:

1. Wait for new grout to cure fully, typically 48 to 72 hours after application.
2. Clean the grout thoroughly, especially if it is old, using soapy water or a specific grout cleaner, then let it dry completely.
3. Protect the surrounding tiles and surfaces with tape to avoid staining.
4. Using a foam brush, small roller, or sponge, apply the sealer evenly along the grout lines. Work in small sections carefully.
5. Let the sealer penetrate the grout for about 5 to 10 minutes.
6. Wipe off any excess sealer from the tiles within 5 to 10 minutes of application with a clean, dry cloth to avoid residue.
7. Let the sealer dry completely and test its effectiveness by dropping water on the grout. If water beads, sealing is complete; if it absorbs, apply a second coat.
8. Allow the sealer to cure according to manufacturer instructions before exposing grout to water or heavy use.

This method ensures grout is protected from stains and easier to maintain. It is recommended to reseal grout annually or when water no longer beads on the surface.
