About this product

Gorilla 100% Silicone Caulk: Kitchen & Bath is a premium white, mold-resistant caulk designed for high-moisture areas. This caulking for bathroom and kitchen applications creates a strong, waterproof seal — ideal for shower caulk, bathtub caulk, tub caulk, and toilet caulk, and effective as a toilet seal — for showers, tubs, sinks, countertops, tile, and backsplashes. Water-ready in just 30 minutes and fully cured in 24 hours, it’s ideal for both quick repairs and larger projects. The highly flexible formula meets ASTM C-920, Class 35 standards, helping prevent shrinking, cracking, or breakdown over time while maintaining a clean, professional finish. Lifetime mold resistance helps protect against mold and mildew, and the cured sealant is easy to clean with soap and water. Perfect for DIY projects and professional use, backed by Gorilla’s Lifetime Guarantee for long-lasting, reliable results. DIRECTIONS: TO OPEN: Cut nozzle at a 45° angle to desired bead size. Completely puncture inner foil seal. TO USE: All surfaces should be clean and free of dirt, grease, oil, and old sealant. For gaps larger than 1/2", use a backer rod. Best if applied above 40°F (5°C). 1. Insert into cartridge gun. 2. Apply sealant, pushing the bead ahead of the nozzle. 3. Smooth bead immediately after application, before a skin forms. CLEAN-UP: Wipe off wet caulk immediately with a dry cloth. Isopropyl alcohol may be used according to solvent manufacturer’s instructions. STORAGE: Store in a cool, dry location with nozzle attached. To reuse, remove nozzle and clean out cured caulk from the tip. LIFETIME MOLD RESISTANCE: Cured caulk is resistant to mold. Clean regularly with soap and water to prevent surface buildup.
