Overview

Gorilla Waterproof Patch & Seal Paste is a thick, flexible rubberized sealant that clings to a wide range of materials to instantly fill large gaps, cracks and holes. When dry, the formula forms a rugged seal that helps keep out water, air and moisture while maintaining surface integrity.

Designed for everyday repairs, this paste offers a ready-to-use solution that adapts to both indoor and exterior projects. It remains workable on various surfaces and can be painted after curing to blend with surrounding finishes.

Key benefits

  • Instantly seals gaps, cracks and holes, reducing the chance of leaks.
  • Adheres to wet and dry surfaces, making repairs faster in real-world conditions.
  • Temperature and UV resistant after drying for long-lasting performance.
  • Paintable to match or complement any color or finish.
  • Suitable for exterior use on roofs, gutters, skylights, flashing and more.
  • Full cure occurs within 24 to 48 hours for durability.

What you can fix

  • Roofs, gutters, skylights, flashing, chimneys and PVC pipe joints.
  • Wood, glass, tile, concrete, brick, stucco, masonry and metal surfaces.
  • Ceramic, porcelain, natural stone, fabric and fiberglass projects.

How to use

  1. Clean the surface of dirt, dust, grease and oil before application.
  2. With a putty knife or trowel, apply a generous coat to cover gaps and fill holes.
  3. Allow the first coat to cure before applying additional coats. Full cure occurs in 24–48 hours.
  4. Wipe away excess material and seal the lid tightly to prevent skinning; rinse tools with mineral spirits as needed.

Tips for best results

  • Apply in thin coats for best adhesion and flexibility.
  • Keep the container sealed when not in use to avoid skinning inside the can.
  • Clean tools immediately with mineral spirits for easy cleanup.
  • Let the final cure fully set before exposing to heavy use or harsh weather.

Note: This product is designed for exterior use in outdoor repairs and is not intended for the interior of fireboxes or chimney stacks.
