Hey guys so my mom had a friend remodel our bathroom like 2 years ago but they didn’t do a very good job painting it and it’s like bubbling detaching in some spots in the closet and avtually bubbled and peeled in a few spots on the wall, Any tips for me or things I should know repainting it? And how should I remove the bubbled areas without edges sticking up? Never painted a room before but am very handy in other tasks and tjink I could do it, most I’ve done is patched the wall and gone over said area with touch up paint. THANKS IN ADVANCE!
