Gorilla Waterproof Patch & Seal Rubberized Sealant Spray, White

Our review of the Gorilla Waterproof Patch & Seal Spray looks at whether this rubberized sealant is a practical fix for common leaks and exterior repairs. Designed for homeowners and DIYers who need a fast, flexible waterproof coating, the product's biggest selling point is its ease of application and self-leveling formula that creates a watertight finish over small gaps and cracks. The pack of six 14 ounce cans promises coverage for multiple patches and projects, and the spray format is convenient for roofs, gutters, flashing, and more.

Key Features

• Flexible rubberized coating: Creates a pliable barrier that seals out water, air and moisture to halt leaks without becoming brittle.
• Controlled spray nozzle: The applicator delivers a clean, even coat so users can cover surfaces quickly and with less overspray.
• Self-leveling formula: Smoothly covers small gaps and cracks to form a continuous, watertight surface after curing.
• Temperature and UV resistant: Dries to a coating that stands up to sun exposure and temperature changes for longer-lasting repairs.
• Paintable finish: Accepts both latex and oil based paints (use a primer for oil based paint) so repairs can be blended into the surrounding surface.

Who It's For

This product is best for homeowners, handymen, and RV owners who need to seal leaks on roofs, gutters, skylights, chimneys, PVC pipe joints and window seals where a flexible, rubberized coating is appropriate. The spray format suits quick patch jobs and projects where brushing a liquid would be slower or leave strokes.

It is not intended for continuous submersion or below-waterline repairs, and it may not work on every type of plastic or rubber. Customers with structural waterproofing needs or who require a guaranteed long-term marine-grade seal should consider specialty products designed for constant immersion.

Pros & Cons

Pros
