This Is How Many Coats of Primer You Need for the Perfect Paint Job ![Solved! How Many Coats of Primer to Use When Painting]() *Photo: istockphoto.com* ## Q: I’ve given in to my daughter’s request to paint her bedroom pink. Is primer required for a job like this and if so, how many coats of primer should I use? **A:** Although paint might initially stick to an unprimed wall, you risk blotchy, cracking, peeling results if you pass on primer. Comprised of more resins and less pigment than paint, plus solvent and other additives, primer is applied to surfaces as a preparatory coat to improve the adherence of paint. It also limits the amount of paint a surface will absorb, so you’ll need fewer coats of paint for an even finish—a win for your wallet when you consider that primer usually costs half as much as paint. ![Solved! How Many Coats of Primer to Use When Painting]() *Photo: istockphoto.com* Generally, one to two coats of primer will suffice for [painting interior walls](), but how many you'll need depends on the wall material, the paint color, and the type of primer used. Keep reading for the magic number of primer coats for all types of interior painting projects. **RELATED: [The 13 Painting Mistakes Almost Everyone Makes]()** ## Use just one coat of primer if: ### You're painting any color over a white wall. One coat of a high-quality water-based primer such as [Zinsser's Bulls Eye 1-2-3](), the Best Overall pick in our [researched guide to the best paint primers for your projects](), is all you need to bind the old white paint and the new shade, mask stains and recently patched or sanded areas, and reduce the amount of new paint you’ll need for full coverage. Zinsser's oil-based [Cover Stain Primer and Sealer]() is another very good option. Find trusted local pros for any home project [Find Pros Now]() [+]() ### You're using a tinted primer. Primer imbued with the shade of your new paint is helpful when making dramatic changes, such as dark to light or vice versa, as it brings the wall color closer to that of the new hue. Pick up a can of tintable primer, such as [Behr's Multi-Surface Stain-Blocking Primer and Sealer](), and ask the paint department associate to bring it up to 50 percent of the new shade. Thanks to the color adjustment you’ll get with a tinted primer, you can often achieve the desired shade with a single coat of paint! **RELATED: [10 Unusual Tricks for Your Easiest-Ever Paint Job]()** ## Use two coats of primer if: ### You're painting unfinished drywall or plaster. Drywall or [plaster walls]() that were never primed or painted will have areas that are more porous than others. These areas will absorb paint at different rates, resulting in blotches. Two primer coats are recommended in this scenario because much of the first primer coat will be soaked up by the wall; the second coat will replenish any primer absorbed by the surface and hide any flaws in the wall. For drywall, apply two coats of a drywall primer-sealer (like [Behr Premium Plus Drywall Primer and Sealer]()) or high-build drywall primer-sealer (one we like is [Zinsser's Peel Stop Triple Thick High Build Binding Primer]()). If your plaster walls are unfinished, prime them with two coats of an oil-based stain-blocking primer such as [Zinsser Cover Stain]() to prevent the lime stains that affect plaster walls from bleeding into the paint. ### You're painting unfinished wood. Wood that was never primed or painted is even more porous than unfinished drywall. The percentage of solids in most paint isn’t high enough to fill the pores and flatten the grain, so [painting wood]() without a primer will result in an uneven surface prone to blotches and peeling. Two coats of an oil-based primer are recommended on unfinished wood: The higher solid content in primer can fill the pores, level the surface for painting, and mask any knots in the wood. When water-based primer is used on wood, it has a tendency to cause the grain to swell, so if you do choose to use water-based primer, lightly sand the surface after the first coat to flatten and level it. ### You're covering a dark paint color with a lighter hue. Primer is a must when making dramatic wall color transitions from dark to light. Without it, the dark color may continue to peek through even after three or more coats of paint. Your best bet for priming dark walls is with a “high-hide” primer such as [KILZ Heavy Duty High-Hide Sealer and Stain Blocker](), which is formulated to thoroughly cover dark shades. Apply two thin coats of either a white primer or a tinted primer that matches the new paint hue. This will bring the surface closer to the final color and reduce the number of paint coats needed. ![Solved!

Two-in-one paint-and-primer products, also known as self-priming paints, contain a much higher percentage of solids than average paints, producing a thicker coat. [Behr's Premium Plus Ultra Pure Interior Paint and Primer](), which has a 4.5/5 rating from more than 56,000 Home Depot reviewers. Keep in mind that individual coats of self-priming paints work best when used over a similar or lighter color; self-priming paint is also best suited to smooth walls in good condition and can [take longer to dry]() than typical paint. **RELATED: [8 Times You Should Never Skip Paint Primer]()** ## Author Manasa Reddigari has tackled topics ranging from computer software to home remodeling in her decade-plus career as a writer and editor.
