Hi. I am having LVT click herringbone fitted upstairs in 2 rooms floor boards and have a few questions. 1. Will It need to put 6mm ply down, if so is it just lay on top and screw(when level) or do I need to glue it as well 2. If I pay a floor fitter to do so, how much per m2 for supply and fit of the ply. One room is 20m2 and the other is 18m2. Thank you
The plywood with need nailing every 6” in the centres and every 4” around the perimeter. It will need plywood if it’s not flat. It also might need some fibre smoothing compound to make it flat / level
