Gorilla White 100% Silicone Sealant Caulk 10oz Cartridge - Waterproof

In this review the Gorilla White 100% Silicone Sealant Caulk is recommended for homeowners, contractors and DIYers who need a durable, waterproof silicone for kitchens, baths, windows and exterior joints. The bottom line: this pack of six 10 ounce cartridges delivers a reliable, flexible bead that resists yellowing, shrinking and cracking over time, and becomes ready for water exposure in about 30 minutes, making it a dependable choice when moisture resistance and longevity matter.

Key Features

• 100% Silicone: Provides a flexible, long-lasting seal that is fully waterproof and suitable for repeated exposure to moisture without breaking down.
• Fast Water Ready Time: Becomes safe for water exposure in approximately 30 minutes, speeding up projects in wet areas like showers and sinks.
• Does Not Yellow: Formulated to remain white and translucent over time so visible joints keep a clean appearance.
• Wide Application: Designed for kitchen, bath, windows, doors, plumbing and gutters, making it a versatile choice for indoor and outdoor sealing tasks.
• Durable Performance: Resists shrinking and cracking so sealed joints maintain adhesion and flexibility with normal movement and temperature changes.

Who It's For

The Gorilla silicone sealant is ideal for homeowners doing bathroom or kitchen repairs, contractors needing a dependable waterproof sealant for window and door installations, and anyone working on plumbing or gutters where a long-lasting, non-yellowing bead is important. It is also useful for marine and auto applications where silicone's flexibility is beneficial.

It may not be the best choice for projects that require paintable caulk or a non-silicone adhesive chemistry, since silicone typically does not accept paint and has different bonding characteristics than latex or polyurethane products. For users requiring color-matched paintable finishes, a different product would be preferable.
