8 days ago
1 Answer
  • AI-generated
    A: Yes, you can apply this product over existing cement or caulk, though it is recommended to remove any loose or crumbling material first. For the best results, ensure the surface is clean and dry, and consider applying a small test patch to confirm proper adhesion to the old material.

Q: Can this product be used over all weather roof cement?

2 months ago
1 Answer
  • A: Howdy neighbor! While you can apply this rubberized roof patch over existing cement, it is highly recommended to remove any loose or crumbling material and ensure the surface is clean and dry for the best adhesion. Because different roofing compounds can expand and contract at different rates, we suggest applying a small test patch first to ensure the new rubberized coating bonds properly to the old cement!

Q: What is the temperature range for application and curing?

4 months ago
1 Answer
  • A: To ensure the best results with Gardner-Gibson Leak Stopper, you should apply the patch when temperatures are between 50°F and 120°F. While the rubberized formula provides an instant waterproof seal even in emergency conditions, it typically takes about 24 hours to achieve a full cure. For long-lasting repairs, aim for a clear weather window where the surface can remain dry throughout the curing process.

Q: Can this be applied to the bottom of the board if I came thru the ceiling to access the leak?

6 months ago
1 Answer
  • A: Hello, thank you for your question. No, this product is designed for exterior application on the roof surface. It is a rubberized coating intended to seal leaks from the top side where water enters. Applying it to the underside of a board or ceiling will not reliably stop a roof leak, because water can bypass the patch from above.

Q: Can I use this to stop gutter leaks

7 months ago
1 Answer
  • A: Hello, thank you for your question. It could work on metal gutters since it forms a waterproof, flexible seal, but it is designed for roofs, not gutters. Its effectiveness depends on the gutter being clean and rust-free. For longer-lasting results, a product specifically labeled for gutter repair may be a safer choice.
