fixing ply to floor boards

[fixerupper]

I have spent a good few hours of my life laying hard board 8x4's on stage prior to a fit up ,we used to used small flat head nails we called 'em little b******d's....

I'm evidently having a 'brain holiday' or 'extended senior moment' today.

I still don't understand why one would want to overboard with thin ply or hardboard?

• I understand tradesmen using self leveling screed on the concrete ground floor kitchen before fitting Karndean tiles.
  
• I have replaced 'moisture resistant' chipboard with 'marine ply' in our bathroom before tiling.
• I have replaced large sections of T&G chipboard in parents-in-laws' house where previous 'tradesmen' have cut large random chunks out between joists and 'replaced' without adequate support. But I have never 'overboarded', so I'm genuinely puzzled why it would be required.

What function does it perform that I'm failing to understand?

Is it to lay Karndean type floor finishes on uneven bodged about chipboard or very old boarded floors?

My aging wee brain is lost in a loop of 'everyone else clearly knows exactly WHY they need to do it and are discussing the finer points of HOW to do it, but I can't get past the WHY do it'

I keep thinking I must be missing some really useful tip that I can use when I help my boys refurbish their houses.

The best set of kneepads you can find.

Unless the sub floor is uneven or has gaps between I cant see the need either. Or as a substrate for tiling/flooring
Certainly not on chipboard flooring.

Bodged, uneven, old floorboards with chunks missing.
Mum is VERY unsteady on her feet (even sober), and budget wasn't enough to replace the lot.
I fastened the floor down as best I could, then laid the 4mm ply, then wood-effect lino to make it easy to clean.

I'll be fitting floating oak flooring - "solid wood laminate" - later this year, so it makes a good, level solid foundation for that.

As a bonus, it's also reduced a LOT of draughts that came up through the underfloor

Had our extension and 1930's kitchen/dining room knock through all boarded before vinyl tiling was laid, levels up all the uneveness.

Be careful with that for elderly folks unsteady on their feet.

My son's new house has that upstairs and even worse that expensive wood effect Karndean downstairs.

I have learned to hate both with a passion.

Unless she ALWAYS wears slippers with very good non slip soles it can be like walking on ice or wet grass. On our second day there we had to go out and buy such slippers and leave them there. It was lethal walking in stocking feet and only marginally less so barefoot.

The slightest spillage makes for a skating rink.

He is saving up to carpet over the lot! (But a new car came first - priorities, priorities!)

Thanks for the info.
I'll bear it in mind.

I've got an automatic screwdriver. Main use is for drywall / plasterboard but not restricted to just that. You can get a handle that allows operation whilst standing up for flooring. Different length screws available cheaply. Screws load like a machine gun belt and take seconds to install even when 2-3" length. What about hiring one ?

I've seen floorboards "recessed" on the underside to accommodate pipes before though....
