Best Answer: Its OK to skim coat or texture over a painted wall, and yes prep work is everything for how well the job will look and how well it will last. SO do not skimp on the prep. Watch out for wall paper, the water in the mud will cause it to wrinkle and leave air pockets and bubbles the paper.
Before skim coating: 1  Make sure the surface is clean. 2  Use a degreaser to wash painted surfaces that are stained or covered with an oily film. 3  Sand slick, shiny paint surfaces with medium sandpaper or prime with a flat paint and let it dry completely.pply as many subsequent skim coats as needed to build a smooth finish over the repair area. As you work, if there is excessive rippling or other surface imperfections, sand them lightly and wipe the dust away with a damp rag before applying another coat.
