Few things are more frustrating than finishing a painting project only to see brush strokes or roller marks ruining your smooth finish. Fortunately, with the right techniques and tools, you can achieve a flawless, professional look. Here are the most common FAQs on how to avoid streaks and marks when painting walls.
1. Why do brush strokes and roller marks appear?
They usually result from:
- Using low-quality brushes or rollers
- Applying too much or too little paint
- Not maintaining a wet edge while painting
- Skipping surface preparation
- Overworking the paint once it starts drying
2. What type of brush should I use to avoid strokes?
- Choose high-quality brushes with fine bristles.
- Use angled brushes for cutting in at edges and corners.
- Avoid stiff or worn-out brushes, which leave visible marks.

3. How do I prevent roller marks?
- Use the correct roller nap length for your wall surface.
-
¼” nap: Smooth surfaces (drywall)
-
⅜”–½” nap: Light to medium textures
-
¾” nap: Rough surfaces (brick, stucco)
- Roll in a consistent “W” or “M” pattern, then fill in.
- Don’t press too hard—let the roller do the work.
4. What does “keeping a wet edge” mean, and why is it important?
A wet edge means working quickly enough so the section you’re painting doesn’t dry before you overlap with the next stroke. This prevents lap marks and ensures seamless blending.
5. Should I use primer to avoid brush strokes and roller marks?
Yes. Primer creates a smooth, uniform surface that helps paint glide on evenly. It also improves coverage, especially when switching from dark to light colours.
6. How many coats should I apply for a smooth finish?
Most walls need two coats of paint. One coat often looks streaky, while two create even colour and better durability.
7. Can paint quality make a difference?
Absolutely. High-quality paints have better flow and leveling, reducing the chances of brush or roller marks. They also provide superior coverage and durability. Browse Randall’s collectionsfor premium paints.
8. How do I fix brush strokes or roller marks after they appear?
- Wait for the paint to dry completely.
- Lightly sand uneven areas with fine-grit sandpaper.
- Wipe clean, then apply another thin, even coat.
