DESCRIPTION

Thin, long, and relatively straight cracks that form in the paint films, usually in the direction of the plywood grains.

POSSIBLE CAUSE

Plywood is prone to cracking because of its method of manufacture. Plywood cracks from its expansion and contraction with changing moisture contents. Stress are induced which later show up as cracking. Many small fissures are produced in films of paints and stains that have been applied to insufficiently, this can be felt as sharp brush, subsequently, this coating may become detached from the edge of the cracks and lead to flaking.

SOLUTION

• New wood; to prevent cracking of newly installed exterior plywood, sand and immediately prime with A-100 Latex Exterior Wood Primer. Even minimal exposure to the elements will cause unprotected plywood to degrade.
• Repaint: If the cracking is not extensive, clean the surface thoroughly, then sand surface smooth and wipe off dust. The plywood must be thoroughly dry. If cracking is severe replace the wood.
