What paint is safe to use behind a woodburner on vermiculite board? Thanks
Assuming boarding is bare, clean, dry, sound and prepared as detailed in the teechnical data sheet you could consider Tikkurila Muuri.
This can withstand upto 300°C with teh white colour, or upto 180°C with the tinted colours.
We would recommend to check what temperatures the boards are likely to be exposed to.
