I am installing vinyl flooring and am looking to replace the strips between my sub-floor and underlayment.
Main reason is because I had particle-board glued on top and had to replace it and I'm nervous to sand the glue off of the strips because I don't want to affect the height and plus I don't think they're in the best of shape.
The strips are also fiberboard and I rather have something more solid. Currently they are 8ft x 2.5" x 1/2". If I were to get something like this: Poplar Board and lay them the horizontally and space them out instead would this accomplish the same thing?
I am unable to find exact replacements for what I currently have. Also, if the above board would work what's the best way of adhering it to the plywood sub-floor?
Pictures below show what I am looking to replace:
Thanks a lot in advance for the advice!
