How do I remove dried paint from flagstone?
A number of variables come into play. What kind of paint? Oil and water based may act differently. What kind of stone? Limestone is soft compared with granite, for example. How much paint? You will treat spatters, a major spill or painted stone differently. (The bigger lesson here is that specific questions yield clear answers-but back to the problem at hand.) I shy away from chemicals, but you may carefully apply paint remover in the least possible amounts, scrape the loosened paint into a container, disposing of it properly and clean the area thoroughly. Consider sanding, either by hand for a small amount or with a power sander. These are the 2 options i would consider first, though there may be some other good answers too.
