Gorilla's Kitchen and Bath Sealant is a 100. percent silicone-based caulk/sealant formulated specifically for moist environments. It creates a waterproof, flexible seal that resists mold, mildew, shrinking, cracking, and yellowing over time. It becomes safe for water exposure in as little as 30 minutes (depending on bead size and ambient conditions) but achieves full cure in about 24 hours. The product is designed for use around sinks, tubs, showers, faucets, windows, doors, plumbing, and other indoor/outdoor junctions. It typically is available in clear or white variants, is not paintable, and works best when applied to clean, dry, nonporous surfaces above ~40. deg. F.
