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.
You trowel the mud on with a drywall knife or roll it with a roller and then immediately scrape the wall with the knife, leaving only a smooth layer behind. Skim coating works best if done in thin layers, so if the wall is lumpy or has an existing rough texture, it may take more than one skim coat to flatten it.
