Flex Caulk is a versatile sealant that works well in wet environments, making it a great choice to use in and around showers. Its waterproof formula helps seal gaps and cracks in areas exposed to moisture, such as shower tiles, corners, and joints. Flex Caulk can prevent water from seeping into vulnerable areas, helping to keep mold and mildew away. Before applying Flex Caulk, remove any previous caulk with a caulk removal tool, then clean the area so it’s free of any residue, dirt or mildew. Although Flex Caulk can be applied to wet or damp surfaces, dry surfaces are ideal.
