Before applying flexible silicone or acrylic latex caulk to corners and changes of plane in a tile installation, you should allow the fresh grout to cure completely, which typically takes a minimum of twenty-four to forty-eight hours. Applying caulk too soon while the surrounding grout is still releasing moisture and undergoing its initial chemical hydration process can compromise the caulk's adhesion, leading to premature peeling, shrinking, or mold growth along the joints. Ensuring the tile and grout lines are completely dry, clean, and fully set before running your caulk bead guarantees a watertight, professional finish that lasts for years.
