Gorilla Waterproofing Spray – Rubberized Sealant, Black, 16 oz x2 | Seals Water, Air & Moisture

Gorilla Waterproofing Spray: Flexible Rubberized Sealant for Outdoor Protection

Gorilla Waterproofing Spray delivers a flexible, rubberized coating designed to seal out water, air, and moisture. The self‑leveling film fills small gaps and cracks, creating a durable barrier that remains pliable while you finish surfaces. When fully dry, the coating accepts paint and withstands outdoor conditions better, helping your repair work look cohesive and lasting longer.

In real-world use, you may notice a smooth, even texture after spraying, with less effort than conventional sealants to cover uneven spots. The finish is compatible with both latex and oil‑based paints, and you can light Primer if you plan to use oil paints. Because this product is intended for exterior use, it’s formulated to hold up against temperature shifts and sun exposure while maintaining flexibility to cope with substrate movement.

Why this spray can support outdoor projects

• Seals out water, air and moisture with a flexible film that adapts to irregular surfaces.
• Controlled spray pattern helps you achieve an even, clean coat with minimal overspray.
• Paintable after cure, compatible with latex and oil‑based paints; primer is suggested for oil finishes.

How to use for best results

• Prepare a clean, dry surface by removing dirt, dust, grease and oil; ensure the area is fully dry before application.
• Shake well, hold 8 to 12 inches from the surface, and apply evenly in multiple coats to cover gaps and cracks.
• Let each coat cure before exposing to moisture; plan for a full cure of about 24 hours for a robust seal.

Applications span roofs, gutters, skylights, flashing, chimneys, PVC joints, window seals, RV roofs, and various DIY projects. The product is temperature and UV resistant once cured, which helps the seal maintain its integrity in outdoor environments. Note that it is not intended for continuous submersion or below-waterline use, and not for interiors of fireboxes or chimney stacks. For tighter joints or larger gaps, apply additional coats and test the finished area with light water exposure.
