Grout, a definition

Grout is a mixture of cement, curing, sealing and water used for filling gaps or voids between bricks, tiles, mosaics and frames. It is similar to other pastes such as plaster, mortar and joint compound and is commonly applied to embed rebars in masonry walls and seal joints. Although most varieties of grout are cement-based, it is possible to use sand when a thin compound isn't desired.

Tools for groutwork:

• grout saw or grout scraper - a manual tool for removal of old and discolored grout. The blade is usually composed of tungsten carbide.

• grout float - a trowel-like tool for smoothing the surface of a grout line, typically made of rubber or soft plastic.

• grout sealer - a water-based or solvent-based sealant applied over dried grout that resists water, oil, and acid-based contaminants.

• pointing trowel - used for applying grout in flagstone, and other stone works.
