Grout
Definition and meaning of Grout in real estate.
Grout is a dense fluid mixture of cement, sand, and water used to fill the joints and voids between tiles, stones, or marble slabs. It helps seal the gaps, lock the tiles in place, and prevent water damage to the underlying surface.
In more detail
In residential construction, grout is commonly applied in kitchens, bathrooms, and tiled entryways. It comes in sanded and unsanded varieties, with sanded grout preferred for wider joints to prevent shrinking and cracking. Because cement-based grout is naturally porous, it easily absorbs moisture, dirt, and stains if it is not sealed regularly.
Home buyers and owners should inspect grout lines for cracking or crumbling, which can lead to water leaking behind walls or beneath floors.

Frequently asked questions
What is the difference between sanded and unsanded grout?
Sanded grout contains sand for strength and is used for gaps wider than one-eighth of an inch. Unsanded grout is smoother and used for narrow gaps or delicate tiles that could be scratched by sand.
Do I need to seal my grout?
Yes, standard cement-based grout is porous and will absorb water and dirt. Applying a grout sealer once or twice a year helps protect it from staining and mold growth.
