Grout sealer is a protective coating that is applied to grout lines to help prevent stains, moisture damage, and mold growth. It is important to apply grout sealer regularly, especially in areas that are exposed to moisture, such as bathrooms and kitchens.
Grout sealer is available in a variety of types, including water-based, solvent-based, and penetrating. Water-based sealers are the most common type and are easy to apply. Solvent-based sealers are more durable but can be more difficult to apply. Penetrating sealers are the most durable but can be more expensive.
