Old bedroom paint keeps peeling off in tiny flakes while sanding
An old layer of paint often flakes off in tiny pieces during sanding or prep work, preventing the wall from ever getting smooth enough for a new coat. This constant peeling ruins the surface and traps people in an endless loop of scraping and frustration before they can even start painting.
