GORILLA Patch & Seal Liquid Rubber Waterproof Sealant – White, 32 oz

Overview

Gorilla Patch & Seal Liquid Rubber Waterproof Sealant is a flexible, rubberized coating designed to seal out water, air, and moisture. The white formula flows smoothly, self leveling to cover small gaps and cracks, creating a watertight barrier on exterior surfaces. When fully dried, it takes on a paintable finish and offers resistance to temperature changes and UV exposure, helping repairs hold up over time.

Key benefits

• Flexible rubberized coating seals out water, air, and moisture to prevent leaks.
• Self leveling texture fills small gaps and cracks for a smooth, even seal.
• Paintable finish supports latex and oil based paints; primer is recommended for oil based paints.
• Temperatures and UV resistance contribute to lasting durability in outdoor environments.
• Easy application by brush, roller, trowel, dip, or pour for various project sizes.

Ideal uses

• Roofs, gutters, skylights, flashing, and chimneys in exterior settings.
• PVC pipe joints, window seals, RV roofs, metal, concrete, wood, brick, tile, fabric, rubber, and glass.
• Durable sealant for DIY repairs and weatherproofing projects, with a note to avoid gaps larger than 1/4 inch.

How to apply and cure

• Prepare the surface by cleaning away dirt, dust, grease, and oil. Ensure it is completely dry before applying.
• Stir contents for about 30 seconds to fully mix the formula.
• Apply by brush, roll, trowel, dip, or pour; fill all cracks and holes with one or more coats. Allow coats to cure between applications and before water exposure.
• Full cure occurs in 24 to 48 hours at temperatures between 50 F and 120 F. Test the finished project with light water exposure to confirm sealing.
• Paint after curing if desired; for oil based paints, apply a primer first for best results.

Notes and tips

• Exterior use only; not intended for continuous submersion or below waterline use. Do not apply inside fireboxes or chimneys.
• May not work on all plastics and rubbers; test on a small area first.
• Cleanup is with a dry cloth for excess material; mineral spirits can clean brushes and rollers.
• Store by resealing the can tightly after use.

For outdoor projects where you need a flexible, paintable seal that holds up to weather, Gorilla Patch & Seal Liquid offers a practical option. The self leveling formula helps create a smooth seal on uneven surfaces, while its UV and temperature resistance supports lasting results. Always start with clean, dry surfaces and follow with appropriate coats to ensure a strong, durable seal that can be painted to match exterior finishes.
