Seal or Prime Bare Exterior Wood?
I have a small exterior porch of regular bare wood (not pressure treated). The tops and sides of the boards have been primed and painted with latex paint.
The bottom of the boards are still bare and I want to "treat" them. Should I seal them? Or prime them? Or something else?
(Last time they were primed and painted, the rain leaked(?) through and caused the latex paint to develop hanging bubbles of water (hanging down from porch planks.) So I am hesitant to put latex primer and paint on the underside of new bare wood again.
What would you suggest?
