Common Questions From Our Network of Pros
It’s a synthetic copolymer rubber
No. We hate silicone.
You don’t. That’s kinda the point. But if you are unfortunate enough to have to get it off, try a solvent-based caulk remover, a putty knife, and good-old fashioned elbow grease.
It can be applied to active leaks as it will displace the water. We have not done rigorous 30 day submersion testing, but we do hear of folks using it successfully for swimming pools, boats, kayaks, etc.
We don’t recommend it. Try a test patch to see if you are happy with the adhesion.
Use clear glass cleaner, water with a little soap, or mineral spirits on the bead/on your finger. If you’re applying large amounts, you may want to check out our Cobra Nozzle which lays down a neat bead with no tooling required afterward.
