MAPEI Mapesil T is specifically formulated to provide superior flexibility, allowing it to withstand the thermal expansion and structural movement that commonly occurs in tile and stone installations. Because it is 100% silicone, it is far more effective at preventing water penetration in corners and expansion joints than traditional acrylic-based caulks. It is also inherently resistant to mold and mildew, making it the industry standard for showers, tubs, and other moisture-prone areas. Mapesil T is available in the complete MAPEI grout color palette, ensuring that the sealant visually blends with your grout lines for a seamless appearance. For optimal performance, the joints must be clean, dry, and free of any debris or old sealant before application. It is important to remember that this product is not paintable and should be applied as the final step of the installation. For large or high-movement joints, we recommend using a backer rod to control the sealant depth and ensure a two-point bond for maximum elasticity.
