Why customers choose TaskHolt Tools

Overview

Gorilla Waterproof Patch & Seal Liquid is a flexible, rubberized coating designed to seal out water, air, and moisture. This exterior-ready sealant goes on smooth, self-leveling and works on a variety of materials—from metal to brick to glass. Before applying, stir for 30 seconds to ensure a consistent mix.

Why it matters

What makes it useful is its ability to adhere to surfaces and fill small gaps and cracks, delivering a watertight seal that stays flexible as conditions change. When fully cured, the coating is paintable and shows good resistance to temperature and UV exposure, helping repairs maintain their appearance over time.

How it works

Apply by brush, roller, trowel, dip, or pour. The self-leveling formula flows into tight spaces and smooths over irregularities so you do not need to chase every crevice by hand. For best results, apply multiple coats to cover larger gaps, allowing each layer to cure before moisture exposure.

  • Seals out water, air, and moisture for a durable, flexible barrier
  • Self-leveling formula fills gaps and cracks with even coverage
  • Paintable after cure; compatible with latex and oil-based paints (primer first for oil-based)
  • Temperature and UV resistant for exterior repairs

Practical uses and tips

Use it on metal, concrete, wood, aluminum, brick, tile, fabric, rubber, glass, and more. Exterior-only guidance applies; avoid use inside fireboxes or chimneys. Test a small area first, especially if gaps exceed 1/4 inch or surface conditions vary.

  • Roofs, gutters, skylights, flashing, and chimney joints
  • Window seals, RV roofs, plumbing joints, and DIY weatherproofing projects
  • Prepare surfaces by cleaning dirt, dust, grease, and oil; ensure completely dry before applying

Care and maintenance: after application, wipe spills with a dry cloth. Clean tools with mineral spirits and store the container tightly sealed. The product cures to a paintable finish in about 24–48 hours, depending on temperature and humidity.

Important cautions

Not for continuous submersion or below-waterline use. Exterior use only. May not work for all plastics and rubbers. Surface tests recommended.
