Pat, it is sad when people answer that don't know what they are
talking about. The OSB is plenty strong enough, though most
contractors stay with 3/4 BB plyform because you get more pours
out of it. I don't know that I would use OSB with the stem wall
clips, I just haven't used them. Contact the fellas at Ellis for
an answer. I'm old enough to have formed and poured plenty of
walls with 1x material, I've never seen commercial wall work done
Do not put curing compound on the forms. Yes, do put form release
oil on the forms (avoid getting it all over the rebar). Use the
waxy side of the OSB against the concrete and don't worry about
form release, though I would probably use it anyway.
If the walls are above 24", the forms require whalers and stiff
backs or you can create wood framed pan forms. You must have a
source for snap ties and camlocks in your area (some use button
head ties and wedge or Jahn clamps)
