My home has a sandstone basement dated from 1870. The previous owner had the basement painted, most probably with one of those white paints used to paint room walls and so. I wonder if there is a solution to take off the paint and let the sandstone surface free. The basement has around 20 sqm and I am trying to avoid the need to scrub the paint off. Will a pressure washing do the job?
The second question is: after cleaning the paint from the sandstone, which colourless product should I use to protect it while letting the stone 'breath'?
Any advice is welcome! :-)
