I have an osb subfloor and would like to know if I have to use a 1/4 " sheet of plywood over self leveling compound ( if my floor needs to be leveled) or can the 3 in 1 underlayment go right over the self leveling compound?

Also if my floor is level can the 3 in 1 go directly over the osb subfloor or do I still need to lay plywood over my osb subloor prior to laying the 3 in 1 ?


Thanks

As long as the substrate is flat and hard/stout, you can float over it.
