5 Common Mistakes When Painting Walls and How to Avoid Them

Painting walls seems simple, but the end result can be far from ideal if done without proper preparation and technique. Many people make small mistakes that cause the paint to peel quickly, become streaky, or appear uneven. Let's learn 5 common mistakes when painting walls and how to avoid them for optimal and long-lasting results!

1. Not Cleaning the Wall Surface Before Painting
Mistake:
Painting directly without removing dust, oil stains, or mold from the wall.

Consequences:
Paint will have difficulty adhering properly and will peel easily.

Solution:
Before painting, clean the wall using a damp cloth or mild soap. If mold is present, use an anti-mold solution to ensure the surface is completely clean and dry.

2. Not Using a Primer
Mistake:
Applying paint directly without a primer first.

Consequences:
Uneven paint color, wasteful application, and reduced adhesion.

Solution:
Use a primer before the main coat. Primer helps seal the pores in the wall and improves color adhesion, resulting in a brighter and more durable finish.

3. Painting While the Wall is Still Damp
Mistake:
Painting after new plaster or the wall has not completely dried.

Impact:
Paint can bubble, mold can grow, and deteriorate quickly.

Solution:
Ensure the wall is completely dry, ideally 2–3 weeks after the plastering process. Use a moisture meter or allow for good air circulation before painting.

4. Incorrect Painting Technique
Mistake:
Using a brush or roller with uneven pressure or random movements.

Impact:
The paint will appear streaky, uneven, and the color will be inconsistent.

Solution:
Use vertical or horizontal movements in one direction and avoid applying too much pressure to the roller. Apply the paint in two to three thin layers for a more even finish.

5. Not Waiting for the Paint Layer to Dry Before Recoating
Mistake:
Applying a new coat of paint before the previous coat is completely dry.

Impact:
Paint clumps, roller marks appear, and the finish looks rough.

Solution:
Wait at least 2–4 hours before applying the next coat. Check the instructions on the paint can, as drying times can vary depending on the brand and room conditions.

Conclusion

Painting walls isn't just about color; it's also about technique and preparation. By avoiding the five mistakes above, the paint will be neater, more durable, and make the room look fresher.
