    Hi. I am removing old concrete render from a patch of external wall(this part of the wall is now inside due to extension) that has cut stone underneath. While the render comes off with a bit of work using a bolster and lump hammer, when I get to the cut stone,there are bits of concrete left on it that I would like to be able to remove and clean up the cut stone and have as a feature.

    Is the only way to clean this up by sandblasting? The area is 3sq metres and is indoors. Is there any other system that can be be attached say to a drill to clean up the stone work?

    Thanks

    I'm pretty sure you can get a wire brush attachment for a drill - it would be worth a try for little outlay

    You could use acid to dissolve the cement.
    Santrax is one brand. Ask for brick cleaning fluid at any builders' merchant.
