Ordered 40ltrs of roofing 20/10 waterproofing paint, it came in 2 x boxes, 4 tins to a box. One of the tin lids had been dented during transit and leaked about a cupful into the box, which I was able to scoop up back to the tin. Painted my old corrugated cement garage roof, used 2 coats. It dries like a rubberised surface. Water just runs off it, it’s completely waterproof. I had a broken panel so wasn’t sure about it as I could clearly see daylight through it. However this paint covered it no problem, you can’t even see where it was damaged. New Venture Products delivered quick and kept me informed about my order, I would certainly use them again no worries.
