Grout is a thin mortar used to fill gaps between tiles or masonry. It is a mixture of cement, water, and sand, sometimes with pigments and additives. It is pourable or spreadable, depending on the application. It hardens to fill the joint and lock the units together. Grout is not the same as mortar. Mortar is thicker and holds the units. Grout is thinner and fills the gaps. In the kitchen, grout fills the gaps between the tiles on the backsplash. It seals the joints. It keeps water out. It keeps food out. It is the kitchen's grout. It is the kitchen's seal. It is the kitchen's finish.

Grout comes in several types. Sanded grout contains sand and is used for joints wider than 1/8 inch. Unsanded grout is smooth and used for narrow joints. Epoxy grout is a two-part resin that is stain-resistant and waterproof, used in commercial kitchens and bathrooms. Cementitious grout is the standard for most tile work. The choice depends on the joint width, the tile type, and the exposure. In the kitchen, epoxy grout is common. It resists stains. It resists water. It resists grease. It is the grout of the cook. It is the grout of the kitchen. It is the grout of the meal.

Grout is also used in masonry. It fills the cores of concrete blocks and bonds the reinforcement to the block. It is poured or pumped into the cavity. It must be fluid enough to fill the space but strong enough to carry load. Grout is used in machine bases, anchor bolts, and precast connections. It transfers load and locks components in place.
