Painting over Fiddes Hard Wax Oil

[k81994]

Hello! A year or so ago I had some plywood cabinetry installed in my kitchen. I finished it with Fiddes Hard Wax Oil (not sure if that was a good idea...) but since then some of the plywood has got scuffed and discoloured. I'd like to paint a nice bright colour over it to hide the scuff marks.

My question is - will paint adhere to the hard wax oiled plywood? Should I sand and use a Zinsser BIN primer for adhesion?

The wood feels dry to the touch and not waxy, and it's been a year since the HWO application. Any advice much appreciated as I am a newbie to all this! Thanks

Wire wool and meths to clean.
Give it a coat of Zinsser BIN.

See what happens

Years ago a customer asked me to paint an oak desk which I assumed was varnished. Nope it had a factory sprayed hard wax finish. Although I had given it a light sand, the acrylic u/c would not pass the scratch test. I would have used meths had I known it was wax but decided that it would be quicker to sand the whole thing back.

After sanding, I applied another coat of acrylic undercoat and then two coats of oil based eggshell.

Thanks very much for this, opps. So do you recommend using meths and then applying some coats of paint? I am reluctant to sand very much since it is plywood. Cheers

Yeah go with the meths and wire wool. Do a test area to ensure that the meths does not activate the glue. I think it unlikely to do so. If you plan to use waterbased paint, you might be better off with "synthetic" wire wool (AKA plastic abrasive scouring pads). The reason being that remnants of wire wool might rust

Thanks again. I think I'll use Zinsser BIN so probably okay to use the wire wool?
