Yes. Maybe get a large floor or roof tile or a half height brick and put
the board on it (in the oven). The brick will keep the heat while you
remove it from the oven for spraying but it will take longer to heat up
(an hour or more). A small metal ashtray upside down could serve the same
purpose but work faster.

I use a forced hot air box that is used only for this purpose. At 60-70C
you only need a cardboard box and a thermostated fan. As I said, the
preheating removes the dust problem. The mist is essentially tack dry the
moment it touches the preheated board.
