• 100% Silicone Sealant for Long-Lasting Sealing: Formulated with pure silicone for exceptional elasticity and durability. Ideal for sealing joints and gaps on windows, doors, kitchens, bathrooms, and more.
• WATERPROOF BATHROOM & KITCHEN CAULK: Create a secure seal around showers, bathtubs, sinks, countertops and other moisture-prone areas.

• FLEXIBLE SEAL THAT MOVES WITH THE JOINT: Unlike rigid fillers, the cured silicone caulk maintains elasticity as joints expand, contract or experience normal movement. Its flexible finish helps reduce cracking, shrinking and separation over time, making this RTV silicone sealant a reliable choice for areas affected by temperature and environmental changes.
• MULTI-SURFACE ADHESION FOR CLEAN RESULTS: Designed to bond effectively to glass, ceramic, porcelain, enamel, aluminum, stainless steel and coated wood. This all-purpose silicone sealant supports clean, professional-looking caulking around fixtures, frames and connecting surfaces when applied to properly prepared, dry and contaminant-free areas.

Suitable for residential, commercial and general construction use, it provides a durable barrier against water, humidity and changing weather while retaining long-term flexibility.
