Was I the only one who wondered how you'd get the MDF in the
spraygun?

Just let it get a bit damp first.

For clarity: I was refering to spraying the resin and chopped glass onto
molds and the cement that they use for making those conrete rings
beloved of civil engineers everywhere, are sprayed onto their molds too.
So tell me; how is the saw-dust that is turned into MDF, applied to the
presses?


I don't know whether this is typical, but it is a description of end-to-end
process for MDF production.

so the matt isn't sprayed as such, but fibres dropped and allowed to settle
to the desired thickness. 23cm - 69cm thick! Pressing of 330seconds for
16mm board means it isn't a particularly quick process but the size of the
presses is pretty impressive - anything up to 2m x 20m !!!
