Yes guys its that old favourite again! reading the previous posts re solid flooring over concrete I propose to lay 18mm ply over concrete and then use portanailer to secret nail in tongue, question is should I fix ply to concrete (screw and plug) or leave loose, its a new build and client wants oak flooring in, no doorframes in yet or skirting so floor levels not a problem. I know ive got to acclimatise timber and leave expansion joint around edge, should I glue anywhere? boards are unfinished and client wants em waxed any brand recommended? Cheers Guys
Personally, i would use battens for this. Ply wont grip as much as the wooden battens will. Check your length sizes and space the batten accordingly. Passy
