Review: Excellent Product - Works as expected. I used it on an outdoor storage box. The water beads up upon contact with the wood now. Use this product in a well-ventilated area. The fumes are brutal. I used it outside, and the fumes still lingered. I used a 3M filter mask when applying it, but still smelled the fumes when I returned to the box to see if it was dry. And the box was outside while drying.
Review: Easy to apply and does the trick - Have purchased other flexseal products in the past, so was anxious to try this spray can which makes it much easier to apply than some of the other products and does a good job of ceiling. Any leaks that you have. I use mine on a corner for a gutter on the outside, and we live in a climate that can vary from 10° below 0 to 101° above.
