What is tile grout made of?
Tile grout is typically made of a mixture of cement, water, and either sand or finely ground limestone. Some grouts may also contain additives like latex, polymer, or acrylic to improve the grout’s strength, flexibility, and water-resistance. The proportions of the ingredients can vary depending on the type of grout and the manufacturer’s formulation. For example, sanded grout typically contains a higher ratio of sand to cement, while unsanded grout has a higher ratio of cement to sand. Epoxy grout is made of a two-part system that includes a resin and a hardener, and it does not contain cement or sand. Overall, the ingredients in tile grout are designed to create a strong, durable, and waterproof material that can withstand the stress of foot traffic, moisture, and temperature changes.
