Gorilla Waterproofing Spray - Rubberized Sealant, Clear, 14 oz | Seals Water, Air & Moisture

Overview

Gorilla Waterproofing Spray delivers a flexible, rubberized coating that helps block water, air, and moisture. When it dries, the clear finish stays low-profile while resisting temperature swings and UV exposure, making it a practical option for exterior repairs and protective seals.

Key benefits at a glance

• Seals out water, air, and moisture with a flexible, self‑leveling coating that bridges small gaps and cracks
• Paintable finish that works with both latex and oil‑based paints (primer recommended underneath oil finishes)
• Temperature and UV resistance helps maintain a lasting seal in outdoor conditions
• Easy application with a controlled spray that delivers an even coat

What it works well on

• Metal, concrete, wood, brick, tile, fabric, glass, and more
• Exterior surfaces such as roofs, gutters, skylights, flashing, and window joints
• RV roofs and various DIY projects where a protective, watertight layer is desired

How to use for best results

1. Clean and dry the surface thoroughly to remove dirt, grease, and oil.
2. Shake well, then hold the can 8 to 12 inches from the surface.
3. Apply multiple thin coats, allowing each coat to cure before exposure to water.
4. Let the full cure occur over 24 hours for maximum adhesion and performance.

Tips and notes

• Test spray on a disposable object first to gauge spray feel and coverage.
• Test finished spots with light water exposure to confirm gaps are sealed; apply additional coats if needed.
• Avoid gaps larger than 1/4 inch and do not use for continuous submersion or below-waterline applications.
• Temperature range for application is roughly 50°F to 120°F; surface should be dry before spraying.

Additional details

Surface compatibility includes latex and oil-based paints (primer advised for oil-based finishes). This exterior‑use sealant is designed to be paintable and to withstand outdoor conditions once fully cured.
