A fluid form of cement used to seal the joints between tiles. It also makes the surface stronger because it bonds the tiles together.

Things you need to know

Properly applied grout is waterproof, but it's still a good idea to go over it with a grout sealer to protect the grout against stains.

Cost Considerations

Smaller tiles will require more grout for the same surface area. It will also take more time to apply the grout. This will add cost for both materials and labor. Grout will cost $75 to $125 for a 30-40 sq. ft. area.

Costs vary greatly by region (and even by zip code). To get free estimates from local contractors, please indicate yours.
