Common Questions
Is there a flex seal that would have saved the Titanic?
That is a job for flex tape.
What solvent is used to clean flex seal up?
You can either wipe it down with a wet cloth or use a citrus based cleaner.
I have a tub that isn't set properly and the caulk that is on it is pulling away and cracking. Will this product work to replace it?
If you fill the tub and it's in the "pulls away" position, then caulk. When the tub is full, the caulk will be in its sealed position.
Is it possible to use flex shot for drive way repairs?
It's okay to fill cracks and holes, but not for large area repairs in place of concrete.
I have a small hole in the pool and I don't know if it will stop the leak or if I have to drain it first.
Flex shot says on the can to apply to a clean dry surface and let set for 24-48 hours, but it never dryed right.
