Checking, Cracking & Flaking
Checking is a pattern of breaks in the top layer of
a coating.Cracking and flaking are advanced stages of checking.
Checking results when a coating begins to lose its elasticity, developing
small narrow breaks due to expansion and contraction. These breaks
are on the surface and do not penetrate to the substrate. They usually
follow the pattern of the grain. Further exposure will result in
wider breaks or cracks in the coating that eventually reach the
substrate. As time goes on, the coatings begin to flake off.
Remove as much loose paint as possible.
Use an exterior speckling compound to level uneven
If many layers are involved, remove right down to
Prime all bare wood with exterior primer.
Cracking down to the substrate usually means complete
removal of the existing coatings.
Apply a flexible topcoating such as water-based acrylic.
