My mother is trying to remove paint from a wall using my RO 150 using some of the Cristal paper. The paint has been on the wall for several years (so dry/cured); I think it might have been sponged on or something. The paint is sticking to the paper in solid clumps - not the typical dust that gets stuck in the paper, but hard pieces of paint that we can kind of pry off.
Even more strangely, the paint was getting under the pad and sticking to the back of the pad in similar clumps.
I don't think we've ever seen this happen before, but the clumps on the paper get so thick that I believe they are holding the abrasive away from the wall and slowing progress - for now, she is pulling it off once in a while, but why would it be doing that to begin with, and any ideas on how to improve on this situation?
