What size MDF for desk?

Worst how much girth do you have thread ever.

I kid :)

Why not fork out for a nice piece of wood? There's a build log in the cases category where a guy builds a desk around his PC. MDF sounds not to pleasant to use.
 
Yeah should be fine. If you can find it get the marine grade. I think its called medex and its green. It won't ever swell up even if stood in water. Mdf can swell with just minor amounts of water over time (condensation from beer bottles etc.). Use Mdf primer as well if you intend to paint it.
 
Yes, my desk and the one upstairs are both 18mm MDF. The upstairs one has been in place 5 years and parts of it are recycled from another 18mm MDF desk that was made in the mid 90s.
 
Should do. Use MDF sealer (Rustins stuff is good) as suggested to prevent shifting due to moisture, particularly the edges will need several coats. When you sand between coats you can get the material really smooth and glossy, not at all porous.

Another option is to try to source a small amount of kitchen worktop. I expect builders merchants or similar have off-cut bits quite cheaply.
 
Depends on the length, width and weight on top, but with decent support the thickness doesn't matter too much as the frame will take the weight.

18mm will look pretty naff though. If you can afford it I'd recommend getting some real timber 40mm thick 'butchers block' kitchen worktop. Quite expensive but would look far better and take loads of weight. Its what I'm currently looking into using for mine.

Wear a mask if using mdf as it is really nasty stuff.
 
Do what I'm doing... go buy a kitchen worktop? Comes in 2/3M lengths already finished for you... and usually 38mm thick and 600mm deep.

:p

I'm getting mine from wickes in a few weeks, should be around £70. They have some nice wood look finishes too, rather than the stereotypical glossy kitchen style finish.

Mine will be suspended from the wall, using a back wooden brace on the wall and one on the left and right hidden underneath. I am also adding a support bar midway between the left and right wall which will consist of a steel square bar to ensure the desk does not sag.

So once said desk is built, do I first sand, coat of primer, second sand, second coat of primer followed by a varnish?

If so, I'm thinking beech or maybe oak.

I think I would find 38mm too thick.

Get 28mm then. You have worktop or "breakfast top" which are generally 2m x 900mm x 28mm. Depends how deep you want the desk really. Mine is well over 900 deep at the present time... and it's a bit too much for me, 600 sounds perfect.

On top of that you get a very hard working surface so you can't wreck it.

You wouldn't happen to have a link of this thread would you? Just searched for wooden desk but couldn't seem to find it. Sounds interesting.

He's making a desk, not a board room table.
 
my desk is made of 2.6m of kitchen countertop between two trestles and i love it. it's definitely the biggest desk for the money.

60cm deep too
 
You can buy pre veneered or laminated MDF. Saves the ballache of painting it and should be a nicer finish.

That ot laminate it yourself if you happen to have a vacum former to hand... :p
