Lifting / Solvent Aggression

The topcoat dissolves the underlying layer, leading to wrinkling, swelling, or bubbling.

Description:

Lifting or solvent aggression is usually caused by unsuitable painting conditions or incompatible paint layers.

Cause:

1. The topcoat is applied before the underlying layer has dried.
2. Insufficient evaporation time between layers.
3. Poor solvent resistance of the undercoat or too strong a solvent in the topcoat.
4. Poor adhesion of the underlying layer.
5. Coats applied too thickly.

Repair:

1. Lightly sand the affected area, seal the surface, and repaint.
2. Be especially careful with sensitive substrates: keep each coat thin and allow sufficient evaporation time.
3. If the lifting is severe, completely remove the affected area and reapply the entire paint system.

Recommended products to prevent and correct possible issues:

• Abrasives and accessories

• Paint spray guns
