Other forms: grouts
Grout is the paste pressed between tiles to fill the joints. Apply the grout, clean the grout, mouldy grout.
It seals the gaps and stops water getting behind the tiles, and it is the part that fails first — grout goes mouldy and cracks long before any tile does. Silicone is used where two surfaces meet at an angle, because grout there will crack.
