The good news? Learning how to avoid brush marks isn’t complicated. With the right tools and a few expert tricks, you can get a flawless, professional-looking finish. Let’s dive into the details!

Key Takeaways

  • Use high-quality brushes and self-leveling paints to reduce visible brush marks.
  • Apply paint in long, smooth strokes, avoiding overworking drying areas.
  • Thin thick paint slightly with a conditioner for a smoother application.
  • Maintain a wet edge and work in sections to prevent overlap lines.
  • Lightly sand between coats for a polished, professional interior house painting finish.

How to Avoid Brush Marks When Painting

If you’ve ever finished painting and noticed streaks everywhere, you’re not alone. Using the wrong brush, applying too much paint, or going over drying paint are common mistakes that lead to brush marks. But don’t worry—this is totally fixable.

1. Choose the Right Brush and Paint

This might sound simple, but it’s a game-changer. Cheap, stiff brushes leave streaks, while high-quality brushes create a smooth finish. Soft, tapered bristles hold paint better and release it evenly, which helps prevent those unwanted ridges.

Paint choice also matters. Self-leveling paints are designed to smooth themselves out as they dry, making them ideal for cabinets and trim. If you’re painting walls, a high-quality interior house paint with good coverage is your best bet.

2. Apply Paint with the Right Technique

Let’s talk about brush technique. How you apply the paint makes a huge difference.

  • Use long, smooth strokes instead of short, choppy ones.
  • Follow the grain if you’re painting wood surfaces.
  • Don’t overload the brush—too much paint can lead to thick, uneven strokes.
  • Resist the urge to go back over drying areas! This is the biggest reason for streaks.

Keeping a steady hand and a consistent motion will give you that pro-level finish.

3. Thin the Paint for a Smoother Application

If your paint is too thick, it won’t spread evenly. That’s where paint conditioners come in. Adding Floetrol (for latex paint) or Penetrol (for oil-based paint) helps the paint flow better and levels out brush marks.

Just be careful—too much thinning can reduce coverage. A little goes a long way.

4. Work in Sections and Maintain a Wet Edge

Ever notice lines where one section of paint dried before the next was applied? That’s because the paint wasn’t blended properly. Working in sections and keeping a wet edge helps avoid this.

Here’s how:

  • Paint small sections at a time.
  • Overlap strokes slightly before the paint dries.
  • Move quickly enough to blend everything smoothly.

This method prevents patchy areas and ensures a seamless look.

5. Lightly Sand Between Coats for Perfection

Even when everything is done right, minor imperfections happen. A light sanding between coats can make all the difference.

Use a fine-grit sanding sponge to smooth any rough spots. Then, wipe off the dust before applying the next coat for that flawless, streak-free finish.
