Solid wood over floorboards

[danped]

I'm planning on installing some solid wood parquet flooring. The room is 3.5m x 4m. Wood size is 15mm x 600mm x 90mm and wil be acclimatised first for a week in the room. I'm installing over existing floorboards which are flat. It is a ground floor with a void under the foorboards and some fibre glass insulation underneath it.

My plan is to undercut the existing skirting boards with a multitool, I am screwing down the planks with secret screws:

I was thinking 3 screws per plank. I am putting down Duralay Timbermate over the existing planks. Then I plan to border the room with a single plank thick frame, leaving expansion gap of 1cm. Then fill in the middle with my parquet pattern.

I have done several wood floors over the years so happy with diy. Any advice on my plans? Am I making any howlers.

Thanks
Dan

You cant install Solid wood with an Underlay.

You should only install an underlay if you are floating a Engineered Wood, Laminate or LVP floor.

The correct way to install this will be to 6mm SP101 Ply the floorboards and glue the solid wood to the Ply with wood floor adhesive.

You'll only be able to undercut the Skirts on two walls.

Are the skirting boards properly attached (some plastered/nailed in 10 inch Victorian jobbies) or are they just resting there (modern bit of mdf, pin nailed/gripfill'd in place?)

Thanks for the replies. I am now going to 6mm ply the floor first. I'll drop the underlay. The manufacture instructions do say I can nail and glue, so I'm still planning on going with the screws. Good point on the skirting undercut. The skirting is wood and nailed in, not Victorian but not MDF.

The under cutting of the skirt is going to look a right mess with a multi tool. I would take off the skirt then even cut away a bit of the plaster right at the bottom if there is any so you can get the floor right under the skirt and still have expansion gap when its put back.

There’s is no point in screwing, just use the right glue and save yourself a whole load of time.
