Does anyone know of a good way to remove black bitumen adhesive painted onto concrete? It's the type used to stick parque flooring in place. Chipping it away with a hammer and bolster chisel does a good job, as it takes a fine top layer of the concrete finish off, but it's tedious and hurts. Angle grinders fitted with disks or brushes make a serious mess and the smell lingers. The floor does not have a screeded surface, but is "power floated" to a smoothish, albeit uneven, finish
The reason for removing the bitumen is so I can re-level the floor prior to fitting new floor boards. Not enough room to keep bitumen and lay boards on battens (thought of that one).
