I've used blackboard paint directly on plaster before with ok results
but I want to make one to fix to the inside of a panelled door.

I happened to catch an episode of "How it's Made" the other day on TV
(Quest) and they showed a blackboard being made a metal (unspecified)
surface bonded to a ply backing and then sprayed with blackboard
paint.

Plywood especially from the sheds has a really crap surface finish
that even a lengthy spell with a sander probably can't fix so I was
thinking of a similar approach to the commercial ones shown on the tv.

Would I be better with mild steel, aluminium or something else, maybe
mdf bonded to a plywood backing?

Any recommendations for blackboard paint?

Its steel, allows magnets to stick.

MDF unless you need the steel.

You can buy blackboard paint so I would use that.

Yup, that's what I used when I did one for the kids. nice smooth
surface.

The shiny side of hardboard is a good stopgap.

If you want to use plywood rather than the much smoother MDF then a
good smooth surface for paint can be achieved by using car body filler
applied with a steel scraper and sanded down afterwards.

If you use an angle grinder for the sanding (not really recommended
unless you like a rustic finish) you will have managed to use the two
universal uk.d-i-y solutions to all problems in one project.

Yes.

But to be more specific, this looks good
http://www.diytools.co.uk/diy/Main/s...0-ml-black.asp

It claims to make stuff like MDF magnetic and black.

Did you really mean to say that?
