How To use gorilla Waterproofing products
Gorilla Waterproof Patch & Seal Tape
Directions
- Keeping liner on tape, cut tape to desired size. Tape size should be larger than the repair area, extending beyond all edges. Overlapping tape may cause leaks. Round the corners of the patch to provide less chance of tape lifting at corners. When possible, apply tape to both sides of the repair
- Remove the release liner and place tape over desired repair area. Tape cannot be repositioned once applied.
- Rub entire surface of the tape aggressively, especially the edges. Smooth the patch from the center to outer edges.
- Hold the patch in place for 2 minutes to ensure good adhesion. If possible, apply weight to the patch for 24 hours.
Pro Tips
Storage:
Store tape on the top and bottom disc at room temperature. Edges of tape may be sticky.

Frequently Asked Questions
The best Gorilla product depends on the type of leak and surface. For quick patches on pools, gutters, and outdoor surfaces, Gorilla Waterproof Patch & Seal Tape creates an instant, pressure-sensitive seal. For cracks and gaps on roofs, windows, and gutters, the Spray or Liquid formula coat larger areas with a flexible, rubberized layer. For vertical surfaces and seams where you need a thick filler that won't run, Gorilla Waterproof Patch & Seal Paste is the right choice.

Each format is designed for a different type of repair. The Tape is a peel-and-stick patch for fast, targeted seals on pools, gutters, and outdoor materials. The Spray is a rubberized, self-leveling aerosol that coats irregular surfaces and small cracks evenly. The Liquid is a paintable, brush-on coating ideal for covering larger surface areas like roofs and skylights. The Paste is a thick, trowel-applied formula for filling gaps, seams, and vertical surfaces where a liquid would run.
Yes. All Gorilla Waterproof Patch & Seal products are designed for both indoor and outdoor use. They are UV resistant, though prolonged UV exposure may cause clear formulas to yellow or discolor over time.
Yes. Gorilla Waterproof Patch & Seal Spray and Liquid are both paintable. The Spray is compatible with both latex and oil-based paints; if using oil-based paint, apply a primer first. The Liquid can also be painted over once fully cured.
Gorilla Waterproof Patch & Seal Spray can be used on fountains but it is not recommended for continuous water submersion.
All four Gorilla Waterproofing formats work on gutters. For a pinhole or crack, the Tape provides an instant patch. For seam gaps or multiple small cracks, the Spray or Liquid coats the surface evenly. For larger gaps or vertical seam repairs, the Paste fills and seals without running. Clean the gutter surface completely before applying any product, and allow full cure before rain exposure.
Yes. The Tape, Spray, Liquid, and Paste are each available in Black, White, and Clear. Choose a color that matches your surface for a cleaner finish, or select Clear when you want the repair to remain as discreet as possible. Note that clear formulas may yellow with prolonged UV exposure.
To test a Gorilla Waterproofing repair, apply light water exposure after full cure. For the Spray and Liquid, if the test reveals any remaining gaps or seepage, apply additional coats and allow them to fully cure before re-testing. For Tape repairs, check that all edges are fully adhered with no lifting before exposing to water.
