Tips for Painting Lightweight Brick Walls to Prevent Fading

Why Do Lightweight Brick Walls Require Special Treatment When Painting?
Lightweight brick walls have different characteristics than red brick. Their surfaces are smoother and tend to absorb water more quickly, so if not properly prepared, the paint can fade, peel, or not adhere properly.

To achieve optimal and long-lasting paint results, there are several important steps to consider before and during painting lightweight brick walls.

1. Ensure the Wall is Completely Dry
Before starting to paint, ensure the lightweight brick wall is completely dry after the plastering and plastering process. The ideal drying time is usually around 2–3 weeks, depending on weather conditions.

If it's still damp, the paint will have difficulty adhering and can cause bubbles or mold.

2. Clean the Surface of Dust and Dirt
Use a soft brush or damp cloth to remove dust, cement residue, or stains from the wall surface.
A dirty surface can hinder paint adhesion and result in uneven results.

3. Use a Primer Specifically for New Walls
A primer or alkali-resistant primer is essential for new lightweight brick walls. Primer functions to close the pores of the wall and prevent excessive paint absorption. This ensures the main paint color adheres more firmly and lasts longer.

4. Choose Quality, Weather-Resistant Paint
Use high-quality wall paint, especially one with the following features:

Anti-mold and mildew

UV resistance

Strong adhesion

Color fades easily

For exterior areas, choose weatherproof exterior paint, while interior acrylic emulsion paint is sufficient.

5. Apply at Least Two Coats of Paint
The first coat serves as a base coat, while the second coat strengthens the appearance and durability of the paint.
Ensure each coat dries completely before applying the next coat (usually 2–4 hours).

6. Avoid Painting During Humid or Rainy Weather
Weather conditions greatly affect the final result. Avoid painting when the air is too humid, as this can slow the paint's drying time and make it prone to peeling.

The best time to paint is during sunny, dry weather.

Conclusion
Painting lightweight brick walls is not difficult, as long as it is done with proper preparation. From ensuring the walls are dry, using a quality primer, to choosing the right paint — all these steps can ensure long-lasting, fade-resistant wall paint.
