What is the difference between caulk and grout?
A. Grout is used to fill the spaces between ceramic tiles. When dry it has the texture and character of cement. It should only be used between products of the same type, usually ceramic or stone tile. It should not be used at the seam between tile and any other product, especially wood or wallboard. Products respond to heat, cold and humidity in different ways and grout is not flexible and will crack and fall away as different pressures are exerted by the different products it is attached to. Caulk is a very flexible sealant and is ideal for filling the gaps between different types of products. It usually comes in tubes and is applied with a caulk “gun”. Caulk comes in a variety of colors, and types for different material and uses. A thin, well applied bead of caulk between the last row of tiles and the floor or tub will provide the same look as grout, but will remain flexible and attractive for years.
