OSB was used instead of plywood for my roof. The OSB overhangs by about 12
inches on all sides of the house exposing the bottom to the air. Some water
does get splashed on the OSB on 2 of the sides of the house during storms.
The OSB has been flaking -- exfoliating. The OSB was painted, now I'm
re-painting the house.
What can I do to help stop the flaking? I'd like to avoid building something
under it. Is there something I can use before I put primer and topcoat down
to try to seal it and keep it from eventually flaking away?
I've decided that it might be good to peel off some of the badly flaked
My house was built in 1987 and still has it's original paint.
