PAINT FAILURES - Alligatoring
Alligatoring is cracked paint that resembles alligator skin, and is generally found on wood surfaces. Alligatoring occurs when paint cannot adhere to a glossy surface, when a second coat of paint is applied over an inadequately dried first coat of paint, weather aging, excessive coats of paint, or when the finish coat expands and contracts at a greater extent that any underlying coats. Paint must be completely removed when alligatoring has occurred to ensure an even and uniform finish. Wood surfaces should be primed with a top quality alkyd primer and acrylic latex finish. This is extremely expensive and it would probably be cheaper to replace siding.
