Gorilla Waterproof Patch & Seal Rubberized Sealant Paste – White, 1 lb Can

Overview

Gorilla Waterproof Patch & Seal Paste is a thick, flexible rubberized sealant that clings to a wide range of surfaces to instantly fill large gaps, cracks, and holes. When applied, its high-strength formula dries into a durable, water-resistant seal that helps keep out water, air, and moisture for lasting repairs across both indoor and outdoor projects.

Why shoppers choose it

Versatility and ease of use matter for everyday repairs. This paste works on wet or dry surfaces, and once cured it resists temperature changes and UV exposure. It is paintable, so you can blend the repair with surrounding colors after it dries.

• INSTANTLY SEALS OUT WATER; AIR; AND MOISTURE: Thick, flexible fill closes gaps and holes for a solid seal.
• APPLY ON WET OR DRY SURFACES: Ideal for stopping leaks on roofs, gutters, skylights, and more without waiting for perfect dryness.
• TEMPERATURE AND UV RESISTANT: Cures into an enduring seal that holds up under sun and changing temperatures.
• PAINTABLE: Finish the repair to match any color or surface once cured.

What surfaces it covers

• Wood; glass; tile; concrete; aluminum; metal; brick; stucco; masonry; copper; fabric; fiberglass; ceramic; porcelain; natural stones; roofing; PVC; and more.

How to use

1. Clean the surface of dirt, dust, grease, and oil before applying the paste.
2. Using a putty knife or trowel, apply to the surface and press to fill all gaps and holes.
3. Allow to cure between coats; full cure typically occurs in 24–48 hours. Wipe away any excess material with a dry cloth.

Tips and best practices

• Skinning inside the can may occur if the lid isn't tightly sealed. If present, remove the skinned material and reseal the lid promptly.
• Cleanup is simple: wipe with a dry cloth or paper towel; use mineral spirits for tools like putty knives or trowels.
• Dry time begins when exposed to air and moisture, so plan accordingly for your project timeline.
