Traditional tile types like ceramic tile, porcelain tile, and natural stone tile should not be installed without grout. The addition of grout ensures that debris and dirt do not build up underneath the tiles and cause expansion or movement. Grout also keeps moisture from penetrating under the tile's surface, which can shorten their lifespan. Grout is available in several varieties including
mold- and mildew-resistant,
stain resistant, and
no sealant required. The Home Depot's expert installers will help you select the type of grout that best fits your space.
