sealing and painting MDF
Morning all
Has anyone one here ever successfully painted MDF? I was going to cover the centre section of my dash in vinyl but there are a lot of small curves
which I think will not easily cover and look good.
My next idea was to seal the MDF then spray in car paint. Has anyone here done this and if so what did you use to seal it and how well did the paint
stick?
Many thanks
Nigel

I made some speaker pods for my first car, a MK1 Fiesta, out of MDF. I mixed some PVA glue with water and painted it onto the MDF, let it dry/harden
then used a can of grey spray paint from halfords to finish off. Paint stayed on al the time I had the car.

Melamine paint is perfect, covers and seals really well.

I'll second the melamine paint and matching sealent as said.
Use a sponge roller to put it on and it dries really nice and smooth. You can always rub it back between coats to get the best finish possible.

agree to rubbing back as you get pin sized bubbles otherwise.
BTW it aint that scary a job you dont need to go and get 'cacking' in the garage lol

I've primed MDF with bog standard wood primer. Worked fine.
You'll need to seal the cut edges very well. MDF swells at the edges when it gets wet. On a car that's difficult to avoid...
I used ply in the end for my dash as MDF ain't the lightest product on the planet.....

You could try some sanding sealer from timber yards or good DIY shops. Its used for sealing wood prior to polishing or varnishing.
Avoid anything "wet" as it will cause the MDF to swell.

I worked in a car body shop in New Zealand and we sprayed some kitchen units that had been made of mdf with normal car primer, flatened it back,
another coat of primer, flatten back and then used gloss car paint. came out like a mirror, abeit black, with a bit of polish.
