The Best
This is the best thing ever, used it to fix several cracks in my underground pool steps. Is there was alot of water in the pool and this stuff did what it says. It sealed perfectly, after applying we waited about an hour then put a little more since the steps were submerged in water. It has been 3 weeks and it's still good. I would highly recommend this for any sealing job with water

If you know about flex seal than you just get it. This stuff is great

Defective tube of caul
This item fell apart while trying to use it. The cap was nearly impossible to take off. It malfunctioned & was obviously defective. Given that I was unable to get it to work I’m stuck with hazardous material since the propellent is still within the can and cannot be discarded as regular trash. I’ve used flex seal products before and always found it excellent. This tube of caulk was a fluke I think.

Makes a tight seal
Finally found soething to seal the base of the shower tile, where it meets the shower pan. A little messy, not nearly as bad as silicon. Did the job, no more leaking onto the floor. It is compatible with a damp surface.

Was so easy to use and store
Was easy to use, came out at a good speed and didn't hurt my hand, I would definitely use this again for our tub caulking!

We used this on our trailer and in home bathroom!
Verify smooth on application! Sealed everything up very nicely. It's not messy at all. I'd buy the product again.

Works Well
Very easy to use nozzle. Seal was ok, I think my need was a bit unconventional, so it did not seal the way I wanted it to. I was trying to stop a pipe leak. However, as caulk, it works really well.
