I had a leak at the base of my garage, when it rained water would come into the garage. I used Flex Seal on the outside and inside and no more leaking. I had tried everything. Flex Seal is the only thing that has worked. Taken a big load off my shoulders. I also have a raised garden that has warped at the end. I pulled the dirt away from the end, re-screwed the sides together the best I could and then sprayed it with Flex Seal on the inside. I'm confident it will hold now. I'm so glad I bought 3 cans when I purchased.

I went to order this product...only to find that there is no way to order only ONE can. The supposedly 'Free' can costs as much as the first when you add in additional shipping & handling charges. I HATE this kind of thing, but I needed the product, so I essentially bought 2 at full price.

I used this product in my bathroom as my shower walls needed to be replaced. It was great for a temp repair. It kept the rest of the wall from getting wet. Until I can replace kitchen sink great for new liner to bottom of sink. I love this stuff will recommend to all my friends.

I have a partial rubber roof and flex seal is perfect for keeping the seams leak free. Flex Seal is easy to apply and stands up to the elements for years.
