Reviews

Gardner-Gibson Leak Stopper Rubberized Roof Patch, 1 gal is rated 5.0 out of 5 by 5.
Rated 5 out of 5 by from Leak Stoper Good product and the price was right. Ordered online and picked up in store.

Rated 5 out of 5 by from Works as promised, very happy customer I purchased the Leak Stopper to patch the roof of my 5th wheel trailer. I applied it after a heavy rain, the roof was still wet, and it sealed the holes without any issues. It has held up since then, my roof no longer leaks. I will be purchasing more of the Leak Stopper, after the rainy season, to seal the entire roof.

Rated 5 out of 5 by from Awesome stuff! Used this to seal the seams and leaks on the roof of our aluminum camper. Two horrendous rain storms later and it's bone dry inside. Can't speak for how well it will hold up over time from exposure to the elements, but I still have 3/4 of the gallon left to fix any shrinkage or cracks. Super easy to apply, but be warned it's messy and doesn't wash off of skin...

How long does this product need to curr before coating with Gardner flexx seal coating?

Asked by: Goseegus
Wait at least a week, you may have some "bleed through staining" but that should not affect the repair. If you have not installed the Leal Stopper Rubberized Patch, do not. Instead use the Flexx Seal Liquid Coating for the repair, as it will work much better.
