painting MDF
locoboy - 29/4/07 at 06:11 PM

I have a small bit of MDF on my dash that i need to paint black.

Is there a special paint i need to use or will any old paint adhere?

I would prefer to aerosol paint it but brush would be ok if i had to.

I dont just want to slap it on and see if its ok, because it took me ages to make the bit and i dont want to F**k it up!

Emulsion paint is usually use on MDF

Best to use something like a PVA water mix 50/50 to seal the MDF first. Then flat it back and use whatever paint you like... If you don't then paint will soak into the material and look crap.

As above, or use an MDF primer. About 5-10 quid from B&Q. It'll stain easy if you don't prime it.

Melemain (spelling) kitchen paint.

Yep, another vote for Melamine (?) paint from me, no priming needed, and if i remember, pretty cheap too.

I made my dash from 19mm MDF, put the radii on it (19mm on bottom edge, 9mm every where else) then sealed it with PVA before painting the back with hammerinte (rough but effective) and covering the front with vinyl.

Carefull painting MDF. If any part of it gets wet, it will expand and ruin it.

Hence the need to seal it with the first coat, so other coats don't soak in. It takes a fairly constant soaking over a few hours to expand in truth.

Blackboard paint should work. Aerosol just soaks in because it's so thin. I left some unpainted MDF out on the yard and it was there for months in all weather without any serious problems. It has to be really saturated to split it.

Yeah it probably would, as is not laminated in the first place!
