The Importance of Grout Sealer
Grout sealer is an important product that should be used after you have properly laid your tile. When you finish your tile with grout, you will notice that the grout is grainy and sponge-like in appearance. Grout looks this way because it is known to be porous (will absorb liquid or other coloring if exposed). In order to reduce the porous properties of your grout, you should apply a grout sealer.
Reduce Staining
Applying the sealer will reduce the effects and appearance of staining. You will never have to worry about spilling a pot of red spaghetti sauce on your grout and needing to pull out the bleach to clean it up.
Reduce Moisture
Sealing the grout will reduce the penetration of moisture in and around your tiled surface. This is especially important in rooms that are in contact with steam and humidity (such as bathrooms and kitchens). The sealant will prevent moisture from getting into the grout and eventually lifting the tiles.
Proper Maintenance
The benefits that are derived from sealing your grout, are quickly diminished if you use harsh chemicals or detergents over the sealed surface. Ongoing maintenance of your tiles with mild soaps and detergents is recommended to keep a proper seal.
