Parquet Flooring (Reclaimed)

Not the modern diddy ones. Those like what they had in School assembly halls.

Any of you have experience laying these?

Can I lay them over an existing wooden floor?

I guess I would need to level with hardboard or ply before laying.

Sometime in the past, someone has replaced some T&G wooden floorboard with particle board, but they did not use a flooring grade, so the floor has deteriorated.

I had intended to replace with reclaimed T&G boards, but time is passing, and I have not located the needed size.

Do not want to simply replace the particle board with the right stuff, but if I cannot get back to original floorboards, I may be forced to settle for that. Thought that an overlay of parquet would be a way of creating a solution that appeals.

I think you have a job and a half with how you describe it I would go with T G,

That would be my preference, but finding boards of correct dimensions is proving elusive.

Most timber merchants supply 20 and 18 mm thick t and g flooring. That’s the finished thickness after machining.
You can match the thickness of the existing boards by placing packing between the joists and the underside of the t and g boards.
Where the new boards meet the old ones chisel or plane off the tongue or groove as appropriate.
Although more expensive redwood boards are much better than the white wood equivalents.

Thanks, gaffer, I guess I should give some thought to new wood if I don't manage to find the right period reclaimed material.

Have you got a piece of original board? If you have, you could take it to my mate's place and he would make you some matching boards. He'd do them whatever width you wanted and t&g all 4 sides for you.
That's what I've always done, and I've done floors in many an older house.
Before you put parquet down, cover the boards with ply, at least 6mm, glue and screw it.
Then put the parquet on that, but make sure to use a proper construction adhesive.

Burn't many a Parky flooring in my wood burners...tar and All

Ena are there no reclaimed timber merchants near where you live that have parquet flooring

Not any longer, Peter. Twenty years ago, there were dozens.

Tonker, I take it your friend has a spindle moulder. Woodworker near me did have one, but he did not survive Covid. (I think it is too much work to attempt with a router.)

Yes, Ena, he has all the machines needed to run a joinery/manufacturing workshop, as his family have been doing it on that site since the early 1700's.
Actually, I've got a spindle moulder myself, but not a thicknessing plane, so I'd get him to do it for me.
T'job would be pretty straightforward to me, laaaaike, as I know everything. Apparently!

PS: apart from knowing how to make a device which can sync. my inverter's pure sine output with another inverter or my grid feed!
