Hello, We're trying to remove a bitumen coating from a 8500m2 slate roof. We're trying to find a method of cleaning the tiles so we can sell them on or use them. There's about 3-5mm of bitumen.
We took a sample tile and coated it in a soy based solvent, which cracked it, and the we let it soak in a "heavy duty" Cleaner overnight. And a pressure washer did the rest. Although this worked, its a lengthy process for 1 tile, and we have an entire roof to do.
If anyone has ideas, or experience in this sort of cleaning help would be appreciated.
