The issue of color film being powdery or chalky (Powdery & Chalky)

The paint film appears as a fine powder on the surface, resembling chalk dust. When rubbed, dust adheres to the hands, indicating deterioration of the paint film. It should be addressed promptly as inhalation may pose health risks.

Causes

• The paint film deteriorates due to moisture, external weather conditions, and aging.
• Using low-quality paint with low durability, which has a low amount of binding agents.
• Using interior paint for exterior applications, which is an incorrect usage.

Remedial Actions

• Scrape off the old paint and sand the surface with sandpaper to prepare it. Clean the surface to remove all dust.
• Proceed to paint according to the system, starting with one coat of primer. Recommended: BEGER ProQuick B-1900 multi-purpose primer.
• Apply 2-3 coats of topcoat; for exterior paint, recommended: BEGER Cool Diamond Shield. For interior paint, recommended: BEGER Shield Air Fresh Anti-Virus Gold Ion.
