You can use car paint on MDF with no problems. Acrylic spray cans (standard Halfords) work well, although it might get expensive for a big cabinet. Might be better to hire a spray gun, and buy a tin of white base (and the appropriate thinners) from an automotive refinishing supplier.

Car primer will work OK, too, although you can get specialised MDF primer from B&Q, IIRC. Pay particular attention to the "end grain" of cut boards, as this area will need extra sealing - the cut ends are very porous. If you don't seal them properly, you'll get a matt finish.

My brother made some house signs from MDF. He sprayed them with cellulose primer and colour, airbrushed the lettering, then sealed them with 2-pack laquer. They've been outside for 5 years, and are in perfect condition.

is there any way to get a really good gloss finish? Would using a spray help with that? Can you clearcoat MDF?

Hi,

Have been reading on DIY screens for Front Projection and some say that MDF's can warp , what if it is in a room and not outdoors, will it still warp?

Am thinkin of getting de goo systems paints and doing up either an mdf or plywood as a screen, is this feasible?

Sorry total noob in this...

Thanks for reading

If you are good with a spraygun, you can achieve a perfect glasslike finish. Automotive clearcoat can take a much better finish than DIY varnish/laquer.

With the correct equipment, and good preparation, you can get a perfect finish "straight from the gun" if you use 2-pack clearcoat. Acrylic or cellulose will need a bit of flatting/compounding.
