Have a Weyroc floor fitted over wood joists in a bedroom ... parents
house built circa 1980

Floor is damaged in 2 places (legs of bed had gone through).... dont
really want to re-sheet whole floor, particularly as fitted wardrobes
over part of the floor.

initially thought it would be easy ... make a square cut-out back
flush with joist and fix a bearer timber on joist, to hold edge of new
board, and screw some supports round underside of other 3 sides to
form a frame to fit new piece in.

This plan stuttered today when I measured thickness of the Weyroc
...its 19.4mm. So presumably an imperial 3/4€� sheet.

Anybody know if you can still get 3/4€� sheet ....
If not can you get 20mm as if I have to but 22mm that is not going to
sit flush without a lot of extra work.

I am sure 19mm chipboard is made..mmm...no, butÂ* 18mm is best option
with 1.5mm shims..glue it in




Old venetian blind slats make good shims for this sort of job.
