It was used on a problematic roof as a temporary-economical solution until summer, when a complete repair and insulation will take place. It was diluted with about half a liter of water. It requires a bit of persistence in mixing until it becomes homogeneous. It is thinner than similar products from more expensive companies. When used with polyester fabric, it spreads very well. I am quite satisfied with the result. I do not know how it will perform over time, but as a first impression, it seems good for its price.
