I’m planning on getting a hardwood plywood board to attach to an antique(ish) teachers desk so I will have a larger desk. The teachers desk is only ~2.5x4.5’ and I’m looking at creating a 3x6’ desktop.
My question is, with what should I finish the hardwood plywood? I want to keep/see the wood grain, and would like a finish that will be reasonably durable from day to day wear.
Thanks.
Are you planning to just put the plywood on top, or will the original desk top still be visible so you want to match the finishes?
Just putting it on top. Should there be anything put between the original desk and this top?
The plan is to use some cutoffs to create a ‘frame’ so it cannot move (3 hidden sides) and also to then create essentially a clamp under there as well so it is reasonably stable.
This is not meant to be furniture quality, just nice and large enough for me to enjoy in my basement office and to support multiple computer monitors.
I just put 3 coats of polyurethane on my workbench plywood and it’s doing fine after a year or so. I’ll probably switch to water based poly when my can of oil based runs out since I hear it’s just as durable indoors and easier to clean up after.
