Waterproof 100% Silicone Caulk, White, 2.8 oz Tube

Tackle kitchen, bath, window, door, plumbing, gutter, and even general auto/marine sealing jobs with confidence. This white, 100% silicone formula seals out water, air, and moisture, delivering a clean finish that blends with fixtures and trim. The compact 2.8 oz squeeze tube is perfect for quick fixes, small projects, and hard‑to‑reach areas.

Engineered for long-lasting performance, it’s 100% waterproof and rain/shower ready in as little as 30 minutes, so you can get back to using the space faster. It resists mold and mildew and maintains flexibility to handle joint movement (ASTM C‑920, Class 35), helping prevent gaps and leaks in tough indoor and outdoor conditions.

Made from pure silicone, the sealant won’t yellow, shrink, or crack, and it performs across a wide temperature range for year‑round reliability. For best results, apply to clean, dry surfaces above 40°F. Note: not paintable; not for underwater use, aquariums, brick/masonry/cementitious materials, or metals sensitive to corrosion (such as brass and galvanized). For gaps larger than 1/2", use a backer rod.

Proudly made in the USA, this sealant brings dependable, pro‑level results to DIYers and contractors alike. Choose it when you want American-made quality that stands up to daily use and harsh weather—project after project.
