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

Easy to use
Easier to use than most caulks but still caulking itself is such a task for the inexperienced. Used this to do interior of new installed windows and it worked well, about two normal sized windows per can.

Very disappointed
WARNING DO NOT BUY!!!! Could not get this to work. After 30 minutes still couldn't get any product to come out. Also you can't return for a refund.

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.
