If you see "P1", "P2", "P3", "P4", "P5" or "P6" - you have to order the designated primer as well - just give the number of the recommended primer to the paint store clerk, and they'll know what primer formula to mix for you. To see if the color you selected needs a gray primer for best performance, check the back of the color chip. The primers in Sherwin Williams' Color-Prime system range from P1 (the lightest gray) to P6 (the deepest gray), and it's important to match the right primer with the right color. Have you ever had to apply 5-6 coats of paint, but the color and finish still looked blotchy (often when painting red walls)? The right gray primer would have helped. This step is necessary to achieve optimum color results, and to reduce the number of paint coats needed for adequate coverage. SW Gray PrimersĬertain Sherwin Williams interior paint colors require that you use a special gray primer first. To check, look at the back of the paint color swatch - if you see an "I" in a symbol, you are out of luck - because this color is only suitable for interior use. So before you have your heart set on any specific color, first make sure that it can be ordered as an exterior paint. This is important to know when planning and coordinating your house color schemes. When choosing exterior paint colors for your home, keep in mind that some of Sherwin Williams colors are only available as interior paints. Paint Colors, Charts and Samples SW Paint Colors Psst!
