Too much paint, too little
primer, and water in the wrong
places are some of the reasons
paint jobs don't hold up.
No primer here led to poor adhesion and wholesale peeling to bare wood. One telltale sign
was no trace of any white pigment on the wood or the back of the paint chips.
Make sure you prep and paint the butt edges and butt joints-to prevent this type of water
penetration and peeling. Also avoid painting when the wood is swollen with moisture-lest
it shrink and crack the paint at joints. This is more common with oil-base paint, since it's
less flexible than latex.
