Most people don’t get too excited over grout. Even the word grout is not exactly the most thrilling you’ll find in the dictionary. But grout is an important and useful component when it comes to finishing and repairing tile work.

What, exactly, is grout and what does it do? Grout is a type of concrete that is used to fill joints and repair cracks, usually between tile and stone on floors and walls. Grout is also appropriate for repairing broken tiles. Grout can be considered a type of mortar, similar to brick mortar, only thinner and available in colors that contrast or blend in with the color of the stone or tilework. When dry, grout becomes hard and resists cracking and shrinking.

Not All Grouts Are Created Equal

The type of grout you use depends on the variety and style of tile or other material to be installed as well as the size of the joints between the tiles. Grouts and grout sealants include sanded, non-sanded, epoxy, cement-based, penetrating, and topical – each designed with a particular application in mind. Keep reading to learn about the variety of grouts that exists on the market today.


Some grouts require sealant, though most manufacturers and tile installers recommend sealing grout once it has dried. Two types, impregnating/penetrating grout sealant and topical grout sealant are available. As its name suggests, penetrating grout penetrates the pores of stone tiles and is intended for use on damaged ceramic tiles and on cement-based sanded and non-sanded grout. Topical grout, on the other hand, seals the tile on the surface, protecting it from water and bacteria and enhancing the overall color and finish of the tile. Penetrating grout is not, however intended to repair grout.
