level plywood floor to accept vinyl flooring
I have a ply wood sub floor that is stable has very little flex when you walk on it but is not even and flat enough for vinyl flooring. I need a way to level it.

I though about self leveling cement based underlayment but I am worried about the flex. Adding another layer of ply wood on top of the floor is an option but I don't want to raise the floor to a different height from the surrounding floors.

Any suggestions?

Need more info.
Plywood does not tell enough, Is there just one layer. how thick is it.
Is there a grade stamp on it to tell what kind of plywood it is?
We have no clue what you mean by it's not flat or level unless you tell us how far off it is.

How far apart are the floor joist?

more info
It is normal plywood probably 3/4 inch and the joists are about 16inches on center.

Not to be insulting but I am not sure I can explain it any better it is just a rough floor. If I put linoleum or vinyl it will probably show the bumps in the rough floor.

There has been 100 years of floor stacked and glued on top of it. I have tried to scrape what I can off it but it will take days to get every little bump up and I have already spent 4 hours working on exposing a flat surface.

Want to do it right? Cut it all out and start over with new T & G 3/4 Advantec, screwed and glued down with 1/4" A/C subfloor rated plywood.

Can't he just put down some 1/4" underlay-rated stuff and then put vinyl on that? What's wrong w/ a ply subfloor? His description sounds like variation in the sub floor, but nothing structurally wrong. This is not rhetorical. I'm doing something similar right now and wondering if there is a valid reason why this is bad.

You really need to furnish pictures. If its as bad as you've made it sound, then joes advice is spot on.

If on the other hand you're making mountains out of mole hills then perhaps you can follow inks advise.
