About one yr. ago I completed a sun room with a deck sys using sip’s billed as a smart deck. The 2X6’s that join the 4 ft wide sip’s caused the joints to expand, leaving the panels slightly cupped in the middle, by approx. one eighth of an inch. The finished surface of these panels is seven sixteenths thick osb. I would like to know if anyone knows of a leveling product that can be screed or troweled on this osb that will stick to osb. I am going to apply one quarter inch thick cork panels over the osb, with warmly yours elec. heating on top of the cork ,and five sixteenths thick engineered planks over that. I am told that the osb must be completely level.

Scorpion,
Can it be furred (horizontal) out and then use a wall finish system?

Are the sips used for the floor? I'm confused. Are they concave or convex? Could be a structural issue if they are concave. Prime the OSB with a good oil based primer, and then use a floor leveler mix. But I have more questions about where and what is there.
