Gorilla Waterproof Patch & Seal Tape, Black, 4 in x 10 ft
A useful quick fix tape for small leaks; long term roof seals need a dedicated tape.
The short version
- Homeowners who want a quick fix for small leaks in gutters, vents or downspouts
- Campers and RV owners patching tears in awnings, tarps and trim
- Anyone who needs a temporary patch on a wet surface
- You need to seal a pressurized line such as a garden hose
- The surface is silicone or treated with a water repellent
- You want a paintable or removable repair
What owners like
- Strong grip on clean, dry surfaces
- Easy to cut and apply
- Works on a wide range of patches such as roof vents, canopies and RV parts
Common complaints
- Wet surfaces need a lot of pressure to bond
- Edges stay sticky and pick up dust and grime
- Hard to store once opened because it sticks to other things
- Some patches lift at the edges and leak again, and outdoor life is limited compared with RV roof tapes

What it does
A thick, rubbery repair tape from Gorilla that seals out water, air and moisture on plastic, vinyl, rubber, metal, glass and fabric, indoors or out.
- Extra thick adhesive layer that Gorilla says forms a permanent bond
- Seals out water, air and moisture
- Can be applied to wet or submerged surfaces after scrubbing away debris and algae
- UV resistant backing for outdoor jobs
- Cuts cleanly to size with scissors
A handy roll to keep for quick leak and tear repairs on things like gutters, vents, tarps, canopies and RV trim, and it sticks well to clean, dry surfaces. The trade-off is that wet surface bonds take hard pressure, edges can lift and collect dirt, and RV owners who want a long term roof seal tend to use EternaBond instead.
