How can I remove faux brick from a kitchen wall?
You cannot remove this fake brick without damaging the drywall under. You will have to replace the drywall, best solution, or do one hell of a good skim mud coat over the damaged drywall.  You can use a Rockwell Sonic Crafter or similar tool to cut the drywall cleanly at the edge of the cabinets. replace the drywall, mud it in, and paint.  There is no easy way in this case.
