What is Grout?

Grout is a construction material that can be used to fill voids and seal joints (such as those between tiles). It is generally made up of water, cement, sand. It is applied as a thick emulsion and hardens over time. When mixed and applied correctly it creates a waterproof seal.

Tiling grout is cement based and comes in sanded or unsanded varieties. Sanded contains finely ground silica sand. Unsanded is finer. They can be enhanced by polymers or latex.

Sanded tile grout is cheaper but should not be used when there is a risk of the sand scratching the tile surface, for example glass and certain porcelains.

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