Wood shouldn’t bounce by design. I’m not a fan of the engineered clicks unless glued down.
I’d say the underlay is wrong as you want to movement....
I asked if the floor was level and that can cause movement so that’s why it’s relevant.
For me it shouldn’t be a underlay with any give in it....
Cheapest way take the tiles up.
Or smoothing compound at 10mm to height of the tiles. Could use Timemaster level flex.
Is the concrete dry ? Ho along it been down ?
Is the sub floor level ?
Polypipe is one I’ve heard is really good.
After a few years you get rubbing after some expansion. Loads of 70s houses have T&G and it’s a nightmare. If glued together on joints not as bad.
just not T&G mate
If LVT I’d replace with new floorboards then 6mm SP101 plywood over the top
We don’t whip the bottom but copydex it and cut it in neat.
You need to use a smoothing compound not plywood. SLC some people call it.
like ardex NA , fball stopgap 1200 , Uzin NC150 etc
Go for the pvc interlocking tiles mate
We like using Reisser cutter screws. Go in great. 22mm be best
Stairrods have a great LVT click trim
Why don’t you want a latex screed ?
You must have ordered the wrong ones. you want-
Polyflor Wood fx or Forest fx...
No don’t use silicone. Use quickstep hydro seal.
This man is a con man. Ripped off loads of people in Merseyside. Gave a customer I know a heart attack and caused their marriage to break up....
Take the panels off and trim them now. Get a sample of the LVT and underlay.
