Paint Problems And Their Solutions
10 Paint Problems And Their Solutions
Listed below are 10 paint problems,reasons,and their solutions.
Peeling Paint
Problem:Paint lifts off the surface in flakes due to Poor surface prep (dirt, grease, or moisture). Painting over wet or old peeling paint. Low-quality paint.
Solution: Scrape off loose paint, sand the surface. Clean with soap/water, let dry. Apply primer before repainting.
Cracking
Problem: Paint cracks in a pattern like alligator skin due to applying thick layers of paint, painting over uncured paint, and extreme temperature changes.
Solution: Sand cracked areas smooth, use high-quality, flexible paint, and apply thin, even coats.
Blistering
Problem: Bubbles form under the paint due to moisture trapped under the paint.Painting in direct sunlight/hot surfaces.
Solution: Remove blisters, sand the area.Fix moisture sources (leaks, humidity). Repaint in cooler conditions.
Chalking
Problem: Paint turns powdery and rubs off due toLow-quality, UV-damaged paint.Over-thinned paint.
Solution: Wash off chalky residue. Use acrylic/latex paint for durability. Apply a UV-resistant topcoat.
Mildew growth
Problem: Black/green mold spots on paint due toHigh humidity + poor ventilation.Painting over existing mildew.
Solution: Clean with bleach/water (1:3 ratio).Use mildew-resistant paint.Improve air circulation.
Lap Marks
Problem: Visible lines where paint overlaps due toUneven drying (e.g., rolling over dried edges).Low-quality roller/brush.
Solution: Maintain a “wet edge” while painting. Use high-quality rollers. Work in small sections.

Efflorescence
Problem: White salt deposits on painted walls due to Water seepage bringing salts to the surface.Common on concrete/brick.
Solution: Remove deposits with a wire brush. Seal the surface with alkali-resistant primer.Fix water leaks.

Fading
Problem: Paint loses color over time due to UV exposure (sunlight).
Cheap pigments in paint.
Solution: Use UV-resistant exterior paint. Choose darker/more durable colors
Poor Adhesion
Problem: Paint won’t stick to the surface due toGlossy/unprimed surfaces.Dust, grease, or wax on walls.
Solution: Sand glossy surfaces.Clean walls with TSP (Trisodium Phosphate). Apply bonding primer.

Brush/Roller Marks
Problem: Visible streaks or texture from tools due to Overworking the paint.Cheap brushes/rollers.Paint drying too fast.
Solution: Use high-quality synthetic brushes. Work in moderate temps (avoid wind/sun). Apply paint in smooth, even strokes.
