Thinking about putting down some click together LVT planks in my box room which is about 4m².

The current subfloor is pine floor boards so I was wondering how best to prepare the floor for the LVT planks?

Would some 5-6mm ply be ok screwed down at regular intervals?

I also read it was better to glue down the planks rather than get the click together ones. Does anyone have any thoughts on this and if it's possible for shall we say a "competent" DIYer to do nicely?

I know that even for relatively level planked floors Karndean recommend a minimum of 6mm flooring grade plywood as a sub floor beneath the LVT. This is normally screwed down on 100mm centres. Joints need to be smoothed over using a fibre reinforced smoothing compound
 
I used Moduleo LVT flooring. I used their 'LayRed' range which has its own built in underlay and I think it allows discrepancies of 5mm and can be laid directly onto flooring.

That’ll be for the glue down stuff. No need to worry about joints on the click flooring.
 
So I think if I put down 6mm flooring ply and screw it on the joist centres that should do the job.

All of the 5.5mm in Selco says it is "General Purpose" - would this be good enough?

Should I counter sink the screw heads a bit?
 
Screw heads in sub-flooring always need to be fully sunk to prevent any possibility of them telegraphing through the finished floor in the future. Whilst this is most noticeable with vinyl it does affect other flooring types as well
 
Thanks. Last question - guessing I don't need a LVT underlay if it's going onto ply ?

Again, no expert but I think you do. Very thin stuff. Check with the LVT manufacturer and see what they recommend.
