Think twice before painting over wallpaper if you will ever want to remove the paper. As you shop for paint remember that the color chips and charts are small and the colors will look brighter and darker on your walls. Try larger samples at the window wall, where there is least light, and also on the opposite wall. Look at them in the daytime and at night. It may be well for you to buy paint lighter than you want.
Interior paints vary from high gloss to flat or dull finish.
The choice depends on use. In general, the glossier the paint the more washable it will be. It is especially suited for kitchen and for work and play areas. There are many finishes from which to select for walls, ceiling and woodwork. Each type requires its own preparation of surface and application.
