3. Apply the Grout Sealer
Shake the grout sealer bottle well. Then, while wearing your safety equipment, apply the sealant along with the grout with the foam brush. To allow it to permeate, apply it in thin coats. Apply two coatings of sealer, giving 30 minutes to an hour between each coat.

Remove the masking tape once the second layer has dried. Then, using a dry cloth, polish the tiles to remove any pieces of sealant that you may have missed. after each coat
5. Remove Any Extra Grout

Safety Tips when Resealing Grout
At the time of application, the temperature of the tile and grout must be between 50°F and 80°F (10°C to 26.6°C).
Only reseal your grout in a well-ventilated location (If you’re using an epoxy-based sealer, you won’t need to do this.)
Wear gloves and eye protection at all times when resealing. This is because grout sealers are regarded as irritants to the eyes, respiratory system, and skin.
Do you Need to Reseal Grout?
Yes! You need to. Once the grout has been cleaned, it should be sealed to prevent it from dirt, mold, germs, and mildew. Grout sealers deteriorate with time, so you’ll need to reseal grout on a floor every three to five years.
What Happens if you Don’t Reseal grout?
Cleaning your grout is not enough. If you fail to reseal your grout, grime and water can seep into it, causing fractures and driving your tiles to break at a certain point. By resealing your grout, you can significantly extend the life of your tile surface and reduce damage.
