"We recently moved into a house, which has outbuildings with a unsealed concrete flat roof. Due to persistent dripping we couldn't store anything but we've put this product down and it's totally stopped any water on the ceiling."
"Had a leaky summerhouse flat roof We couldn't see any visible tears or holes in the felt so all I could think was that it was blowing back under the seams Painted over the seams in between the heavy showers we had over the weekend making sure there was a good seal and fingers crossed it seems to be holding One less thing for our lass to witter about :-)
Have given 4 stars for reliability as it hasn't had chance to settle in properly yet"
"I have used this product many times before and it has in most instances performed well. I would say if you need to waterproof a flat roof that does not pool and the product can be applied in the dry, then Flexacryl does a fine job. However I have found that the product can not be applied in damp conditions and it has a very short life span when applied to area which regularly pool water."
