My previous post of Hardwood over concrete is kaput since I hauled 1500 pounds of concrete down 3 flights of stairs. It was too compromised to go over with hardwood. Hj was correct - the tiler who set the tile did it the old fashioned/right way.
Now for the new dilemma.
I have to make up a differential between the hall/dining floor of 2.5 inches (there was a previous step down to the kitchen which I would like to avoid).
The floor, as it stands, is fairly level. About an inch differential over 18 feet. I don't think I need to run sleepers and shims to level - I can live with a slight diff. Besides ,sleepers - 2x4s on the flat - would put me too high with 3/4 ply and 3/4 flooring. ANy other ideas for sleepers? I'm thinking anything less than the 1.5 inch would be weak between the shims.
I'm thinking I might sandwich a layer of 3/8 between 2 layers of 3/4 ply or MAYBE OSB?????? To get me to 2.5 inches with the hardwood (including the 16th they short you on the 3/4 ply).
I guess I have a couple questions:
Is hardwood over OSB kosher? I don't need it for strength. It's just being used for shims over the subfloor.
If not OSB, would CDX be good enough? I know CDX is no good for tile work due to the voids in the ply but will it be acceptable for wood flooring.
I'm trying to avoid the 33 dollar a sheet for two layers of b/c sanded. A combination of OSB and ply might work.
Any ideas or suggestions?
