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
with 2x.

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)

A decent source for products and information:

Can I use wafer board when I form up for my garage stem wall?


No- it wicks like a sponge, and has *no* strength- by the time
you're
done bracing it you might as well have used 2x lumber.

Use 2x12's & decking screws. When you're done you have some
great
shelving for your garage. A quick coat of oil & it comes
cleans
up real quick.

I used two inch lumber for my last foundation 20 years ago.
They fastened together with metal straps and wedges. The lumber
got reused in the floor of the house. No one does it this way
any more locally. I can't buy the straps anymore. I still have
some wedges left. There also is no way to reuse the lumber in
this project though I have a lot of used 2X6's available. Now
they appear to use 3/4 plywood and metal clips at the top and
bottom. I could reuse the plywood to make cupbards inside the
garage later. I thought I could reuse the wafer board. If it
can't be reused it is so cheap I wouldn't care.
