Gorilla Waterproof Patch & Seal Rubberized Sealant Spray - 16 oz Pack

In this review the Gorilla Waterproof Patch & Seal Rubberized Sealant Spray is evaluated for homeowners and DIYers who need a fast, flexible way to stop leaks and protect outdoor surfaces. The bottom line: it is best for patching roofs, gutters, PVC joints and weatherproofing porous materials because it provides a self leveling, rubberized coating that seals out water, air and moisture while remaining temperature and UV resistant. Ease of application and broad surface compatibility are the single biggest reasons to buy for short-term repairs and quick maintenance jobs.

Key Features

• Flexible rubberized coating: The formula creates a bendable seal that moves with substrates to help prevent new cracks from forming after application.
• Seals out water, air and moisture: Designed to stop leaks and block drafts, it provides a watertight barrier on porous and nonporous surfaces when applied correctly.
• Controlled spray applicator: The nozzle delivers an even coat with less overspray, making it easier to cover small gaps and cracks cleanly.
• Temperature and UV resistant: Once cured the coating resists sun exposure and temperature swings, improving longevity of outdoor repairs.
• Paintable finish: Compatible with latex and oil based paints so patches can be topcoated to match surrounding surfaces after priming where recommended.
• Multi-surface use: Works on metal, concrete, wood, brick, tile, glass and more for a variety of home repair tasks.

Who It's For

This sealant spray is aimed at homeowners, handypersons and RV owners who need a quick, tolerant solution for exterior leaks and small gaps. It is particularly useful for roof flashing, gutters, skylights and PVC pipe joints where a flexible, weather resistant patch is required.

It is less well suited to precision indoor sealing, continuous high temperature environments or for inside of active chimneys and fireboxes as the product is intended for exterior use only. People needing a guaranteed long-term structural repair for major leaks should consider professional repair or a dedicated roofing membrane.
