Cromapol White Acrylic Roof Coat Waterproofing Roof Sealant Free Brush & Gloves (Medium)

Used to seal a large felted shed roof that was getting a bit cracked and holed where nails had pulled through. Covered well - used one coat and put a thick layer over the damaged parts - doesn't leak now... no damp patches. Used white hoping to reflect the heat on sunny days, which it has done a fair bit.Just got to get used to a shed roof that looks like its been snowed on - being it's so white now.Happy with results though and glad they supplied free, decent gloves and a brush. Nice touch.

It fixed my leaking trailer roof. Brilliant
