Latex self leveling compound for wooden floor
I have seen/read many accounts of using a latex or vinyl self leveling compound on wavy or sagging floors but cannot find a definitive reference as to what to buy or how to install.
Here's my issue.
I am renovating my almost 100 year old house and the living room is 12 x 24 with poorly maintained T&G maple that is wavy and has some cupping. I would like to install vinyl plank floating floor like Allure on it.
The T&G has been screwed with 2" construction screws into the floor joists in order to reduce the groaning and squeeking in the floor (and that has worked) but we still have some of the mild cupping and waviness.
What I would like to do is to use a filler or leveler just in some of the dips to reduce the waviness.
Remember that the floor is wooden and will still have some movement although not like the trampoline it once was..
I am concerned about using the concrete based products because my fear is that the edges that are feathered to very thin will crack or crumble and then be a poor base for the floating floor above.
So to the group here, what say you? What have you done or used successfully?
BTW - in this case, pulling up the floor or putting another layer of underlayment cannot be done. I have to deal with the floor that I have with a minimal amount of construction, etc as the room is totally finished save for the floor. I had thought of sanding but the amount of dust would be prohibitive.
