How to prepare your walls for decorating

Walls almost always need some surface preparation before you can start painting. Even brand-new plaster needs sealing. You should fill any cracks and holes and make sure all surfaces are clean, smooth and dry. You can paint over emulsion-painted surfaces that are in good condition, but make certain you strip back or sand off any peeling paint.
