LVT onto floating floor

[baker332]

Hi all,

I'm going to be laying stick down LVT in the near future, what's the best way to lay onto a wooden 'floating floor'?

Is there certain prep work involved including treating the wood for moisture? Or/and applying a levelling compound although the wood is dead flat?

Thanks for the help.

By Floating floor, do you mean into a Laminate or engineered wood type floor?

Basically it's the floor of the house upon building therefore joists, jablite between them then a plywood floorboard on top of that.

In that case you need to lay flooring grade SP101 6mm Ply over the subfloor, ensure it’s secured every 3 inches across every sheet, then feather edge or microcoat all the joints and any low fixings and glue the LVT direct to it.

if we were laying Herringbone, we would Mapei Renovation Screed over the Ply before installing the LVT.

We use High Temp adhesive on pretty much everything nowadays to negate any issues with concentrated sunlight, hot spots and of course if underfloor heating is specced
