Smooth Uneven Walls

For the best results from a paint job, repair any flaws in your walls before painting. Kevin Sharkey's contractor, Bob Tobin, explains how to fix a few common problems.

Slightly wavy walls can be smoothed with what Bob calls an "easy skim coat." Apply thin layers of joint compound to achieve a more uniform surface. Each additional coat results in a smoother finish.
