Preparing: Primer - the first step toward a lasting finish. To get a great looking finish coat and the beautiful, long lasting results you expect, be sure to properly apply primer to the surfaces you plan to paint. A good quality paint will:

*Achieve a smooth, professional finish

*Block stains, marks and odors

*Assure adhesion

*Speed topcoating

*Prevent peeling

*Attain the truest paint color in the fewest coats

*Improve touch up performance of the topcoat

In general, the only time a primer is not needed is if you are re painting a surface that's in good condition.
