I am needing some suggestions... here is the situation. The room I want to install peel and stick vinyl planks in has 3/4" OSB subflooring, and the room is in between two other rooms. The manufacture of the flooring stated not to install the planks over OSB and I can not go any higher than 1/8" of additional material over the OSB because the flooring of the other rooms will not match up. I have tried all the surrounding lumber, hardware, diy chain store, etc. looking for 1/8" luan plywood but none of them carry it 1/4" is the thinnest they have. I have wondered if some type of floor sealer or something along that lines would work. Am open to any other material or products you can think of. Any help is greatly appreciated.

That seems like a big problem. Haven't encountered that yet in my home.

Same with me also I have never faced such problem till now..
