I am intending to instal self stick tiles over a primed luan underlayment in a bathroom. However, the manufacturer's instructions clearly state:
DO NOT install over unsuitable or unstable subflooring such as chipboard, OSB, luan plywood, mahogany based plywood underlayments, Masonite™, cement board, fiber based backing boards, or any other non-underlayment grade panel
In trying to understand why the luan would cause an issue, whereas plywood would not, I've since read that luan contains certain "extractives which adversely affect the "cure" of mastic adhesives."
I'd like to find a way to make this work without needing to tear up the newly installed underlayment. Will the primer help in this regard? Is there any additional prep I can do to maximize the probability of a successful installation / adhesion?
