Gorilla Waterproof Coat & Seal Spray 450ml Black is a powerful, easy-to-use solution designed to create a flexible, watertight seal on a wide range of surfaces. Its advanced rubberised formula fills small cracks and gaps, creating a strong, durable barrier that protects against water, air, and moisture. The spray is specially formulated to adhere to a variety of materials, including metal, wood, plastic, concrete, fabric, and more — making it an essential tool for both indoor and outdoor repairs.

This high-performance spray is ideal for quick fixes and long-lasting protection. It dries to a flexible, black rubberised coating that remains intact even under extreme weather conditions. The easy-to-use spray nozzle allows for controlled application, ensuring an even, consistent finish without dripping or overspray. Gorilla Waterproof Coat & Seal Spray is perfect for sealing leaky gutters, repairing roofs, protecting outdoor furniture, and much more.


Key Features:

  • Waterproof Seal: Creates a strong, flexible barrier that blocks out water and moisture.
  • Durable Protection: Long-lasting protection against harsh weather, UV exposure, and temperature changes.
  • Flexible and Elastic: Expands and contracts with the surface to prevent cracking and peeling.
  • Easy Application: Spray-on formula with a controlled nozzle for even coverage and minimal waste.
  • Fast-Drying: Dries quickly to form a rubberised coating that bonds strongly to surfaces.
  • UV and Weather Resistant: Protects against fading, cracking, and damage from sunlight and rain.
  • Multi-Surface Compatibility: Bonds to wood, metal, plastic, concrete, stone, brick, fabric, and more.
  • Seamless Black Finish: Provides a professional, clean look that blends with most surfaces.

How to Use:

  1. Prepare the Surface:
    • Clean and dry the surface to remove dirt, oil, and debris.
    • For best results, sand or smooth out rough surfaces.
  2. Shake Well:
    • Shake the can vigorously for 30–60 seconds before use.
  3. Apply Evenly:
    • Hold the can 15–30 cm (6–12 inches) from the surface.
    • Spray in a steady, back-and-forth motion, slightly overlapping each pass.
    • For thicker coverage, apply multiple light coats, allowing each coat to dry before reapplying.
  4. Allow to Dry:
    • Touch-dry in approximately 1 hour.
    • Fully cures in 24 hours for maximum strength and waterproof protection.
  5. Clean Up:
    • Clean the nozzle by inverting the can and spraying for a few seconds to clear the valve.
    • Remove any overspray with a solvent-based cleaner before it dries.
