How to Repaint a Wall

Whether you’re handling the project yourself or bringing in a professional house painter, knowing the common causes of brush marks and how to prevent them can make all the difference. Let’s break down what you should avoid and what you can do instead to achieve smooth, professional-looking walls.

Key Takeaways

  • Use high-quality brushes and rollers for smooth interior house painting results without brush marks.
  • Properly cleaning and priming walls prevents streaks and improves paint adhesion.
  • Applying multiple thin coats instead of one thick layer helps avoid brush marks.

  • Keeping a wet edge and painting in sections ensures a seamless house painter finish.

  • Final sanding and light touch-ups perfect interior house painting for a flawless look.

How to Avoid Brush Marks on Walls

1. Using the Wrong Brush or Roller

The brush or roller you use makes a huge difference in how your walls turn out. A cheap brush with stiff bristles will leave streaks behind, no matter how careful you are. If you’ve ever struggled to get a smooth finish, your brush might be the culprit.

How to Fix It
  • Choose a high-quality angled synthetic brush for a smoother finish. These hold more paint and distribute it evenly.
  • Use a roller with the right nap length—short naps (¼ to ⅜ inch) work best on smooth walls, while longer naps are better for textured surfaces.
  • Clean new brushes before using them. Rinse them in water (for latex paint) or mineral spirits (for oil-based paint) to remove loose bristles that could get stuck in your fresh paint.

2. Skipping Surface Prep

Rushing into interior house painting without preparing the walls is a recipe for disaster. Dirt, dust, and old paint imperfections will make the new coat look uneven.

How to Fix It
  • Clean your walls first. A simple wipe-down with a damp cloth or mild detergent removes dust and grease.
  • Fill in any holes or cracks with spackles and sand them smooth.
  • Use a primer to create a smooth base. This step is especially important if you’re painting over a darker color or dealing with patchy areas.

3. Applying Too Much or Too Little Paint

Too much paint on your brush leads to drips and heavy streaks. Too little paint means you’ll struggle with visible strokes. Finding the right balance is key.

How to Fix It
  • Load your brush properly. Dip just the bottom third of the bristles into the paint, then tap (don’t wipe) off the excess.
  • Apply in long, even strokes. Short, choppy strokes leave marks behind. Work in sections, blending each stroke into the next.
  • Use multiple thin coats. It’s better to build up coverage gradually than to glob on one thick layer.

4. Rushing the Job

We get it—you’re excited to see the finished result. But rushing leads to sloppy work, and sloppy work leads to brush marks. Taking your time is worth it.

How to Fix It

  • Keep a “wet edge.” This means always painting into a still-wet section to avoid noticeable lap marks.

  • Avoid stopping mid-wall. If you need a break, finish the section you’re working on before stepping away.
  • Don’t skip drying time. Rushing between coats can pull up the previous layer, creating streaks. Always follow the recommended drying time on the paint can.

5. Skipping the Final Touches

Even with great technique, a little extra effort at the end makes all the difference. Don’t assume the job is done as soon as the last coat goes up.

How to Fix It
  • Feather out brush strokes. Before the paint dries, lightly drag a clean, dry brush over the surface to smooth out any uneven spots.
  • Check your work in different lighting. What looks perfect in one light might reveal streaks in another. Adjust as needed while the paint is still wet.
  • Consider a final sanding. If you spot dried brush marks after everything dries, lightly sand the area and add one more thin coat of paint.
