Create a strong waterproof bond between the joints and borders of tiles and seams for your tile installation projects with long-lasting premium caulk. We carry silicone caulk and sanded caulk for designs in high-moisture areas like bathrooms and kitchens, to ensure a secure set for corner shelves, soap dishes and towel bars and to seal areas where grout can crack.
Tiling caulk is a flexible sealant used to fill joints where tile meets another surface or where tiled surfaces change direction. Unlike grout, caulk is designed to flex with movement, helping create a durable seal around showers, tubs, sinks, countertops, backsplashes and tile trim. The most common types are silicone caulk and sanded caulk.
