Adhesive manufacturers will advise 18, 22, 28mm ply for their flex adhesive depending on the manufacturer. If you have a
standard floor board then you have around 22mm, if you ply this then you have 28mm so are in same place.
Personally.
make sure all boards are fixed sound and you domt get any movement then fix your ply to the floor. I use a tacker gun with a 16mm staple in it tacked every 6ish inches.
There is a trick to this, as you move over the floor tacking bounce your hammer over it. Hold your hammer loosley and tap it over the floor. If it bounces you need another tack there if it just thuds its cool. What it does is makes sure you dont have any voids under your ply. Try it you soon get the hang of it,
Prime your ply and off you go
Hope this helps dont be scared of it m8
