Painting over a sponge painted wall
While I am not new to painting I am new to the new techniques of painting. My wife and I are closing on our first house next month. Our problem is the present owners painted the living room a light pink base with a dark pink sponge technique. Looking at the walls they are no large ridges but I can see a slight height difference in the paints and am worried about these patterns showing through after priming and painting. Has anyone painted over walls with this treatment and was there a noticable pattern if you didn't sand? I would rather not sand if possible but want to do this painting once and not have to worry for many years.
