How to Paint Drywall

When to Use a Dedicated Primer:

• New unfinished drywall or significant repairs
• Stains or discoloration on the wall
• Switching from dark colors to light paint color
• Glossy or slick surfaces that might resist paint

Pick the Right Tools

Not all paint tools are created equal, and the ones you choose can impact both the ease of your project and the quality of the finish. Start with paint rollers, as they’re the most efficient for covering large areas. The type of roller you need depends on the texture of your walls.

For smooth drywall, choose a roller with a shorter nap (about 1/4 inch to 3/8 inch). This will apply a thin, even layer without leaving a textured finish. If your walls have a skim coat with more texture or are slightly rough, go for a roller with a thicker nap, like 1/2 inch or more, to cover the surface evenly.

Other Tools to Consider:

• Brushes: Use angled paint brushes for cutting in around edges, corners, and trim.
• Painter’s Tape: Protect baseboards, ceilings, and adjacent walls for crisp edges.
• Extension Pole: Makes it easier to reach high areas without a ladder.
• Paint Tray or Bucket: Keep your paint supply accessible and manageable.
• Drop Cloth: A layer of protection for your floors.
• Damp Cloth: Good for quick wipes when you get a little loosey goosey with the brush or need to wipe away dust particles.
• Pole Sander: A light sand of the entire wall with fine-grit sandpaper between coats of paint helps get you the professional finish.
• Quality Paint: You get what you pay for, quality paint may cover in a single coat whereas cheap paint may require 2-3 coats or more cans of paint.

Apply the Right Way

Once the drywall dust is gone, your surface is prepped, and your tools are ready, it’s go time. Start by cutting in around the outer edges of the wall with a brush. This includes the corners, the ceiling line, and any areas around windows, doors, or trim. Use smooth, even strokes to create a clean edge.

Next, move on to the larger areas with a roller. The best painting process is to work in small sections using a "W" or "M" pattern, then filling in the gaps with even strokes keeping a wet edge. This technique spreads the color more evenly over the entire surface and prevents streaks or visible lines where sections overlap.

Want a flawless finish? Remember These Tips

• Don’t overload your roller; too much paint can lead to drips and uneven surface texture.
• Work from top to bottom to catch any drips as you go.
• Let the first coat of paint dry completely before applying a second or finish coat.
• A gentle sanding with fine-grit sandpaper between coats and a wipe down with a damp cloth gets rid of imperfections and knocks down fuzz that may have come off the roller.

Most walls will need at least two light coats for full coverage, especially if you’re changing to a lighter or brighter color. Be patient, as rushing the process can leave you with a patchy or uneven finish.

FAQ

Can I skip primer if I’m using a paint-and-primer-in-one product?

While all-in-one products are convenient, they’re not always the best choice for new unfinished drywall or walls with stains. A separate primer will give you better coverage and adhesion in those situations.

How long should I wait between coats of paint?

Drying times depend on the product you’re using and the humidity in your home, but most latex paints recommend waiting 2-4 hours between coats. Check the label for the manufacturer’s instructions.
