Before understanding why grout cracks and how long it should last before cracking, you need to know what grout is. Almost every home has tiles installed in their bathrooms, if not anywhere else. So, where there are tiles, there’s grout!Grout is a substance, paste or mortar that adheres to the bisque or edge of a tile, helping fill the gap and crevices between tiles.
