Alligatoring is patterned cracking in the surface of the paint film that resembles the regular scales of an alligator.
What Causes It?
This problem may be caused by applying an extremely hard, rigid coating, like an alkyd enamel, over a more flexible coating, like a latex primer.
Applying the topcoat before the undercoat is dry may also cause alligatoring.
Alternatively, the natural aging of oil-based paints as temperatures fluctuate causes constant expansion and contraction that can result in a loss of paint film elasticity.
Most exterior paint problems and painting mistakes are correctable. Here are solutions for the most common exterior painting problems.
