I've tried Flex Seal clear spray twice without ANY sealing.
1. I used it on a little concrete birdbath. I used 3 coats, and it never worked. So I thought that it had to do with concrete.
2. The rain came through little cracks through the brick in my loft. I saw it used on TV for that exact thing...so I thought great, let me try it. NOTHING. Not even on a sliver in the brick. It just came right through.
It absolutely DOES NOT work and is a waste of money. I can't believe their commercials!
Bottom Line: No, I would not recommend this to a friend
