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).
