DESCRIPTION

Patterned cracking in the paint film resembling the scales of an alligator. These cracks generally do not expose the substrate (e.g. the surface that has been painted).

POSSIBLE CAUSE

• Natural aging of oil-based paints due to temperature fluctuation. The constant expansion and contraction results in a loss of paint film elasticity.

• Application of an extremely hard, rigid coating, like an oil enamel, over a softer, more flexible coating.

• Application of a topcoat before the primer or basecoat is dry.

• Application of a coating over a glossy finish.

SOLUTION

See Lead Information.

• Remove old paint by scraping, sanding, chemical removers, or a heat gun. Follow all manufacturers' cautions when using chemical removers or heat guns.

• Remove all surface contamination by washing with ProClean Professional® Prep Wash Concentrated Cleaner or other appropriate cleaner; rinse thoroughly and allow to dry.

• Glossy surfaces should be sanded dull. Follow label and data page directions for the appropriate drying time for any product.
