Do i need heat proof paint for plasterboard around woodburner?

[nomorespaghetti]

Our woodburner has heatproof plasterboard around it, do I need special paint for it, or will normal matt emulsion be ok? Thanks!

No, but you may need cladding or heatproof board. How far away is it; and how far did the stove makers say it must be?

Plasterboard is made of gypsum and water. When heated, it absorbs the heat, breaks down, and the water boils out, leaving powdered plaster in a pile on the floor (this is why it gives temporary fire protection). I don't know the temperature it takes, but it's one reason why there has to be an airgap.

(plasterboard also has a tough paper coating, which burns)

The stove installers or suppliers may be able to provide or recommend a heat-resistant board. I don't know about this. They should be qualified so should know.

Hi pigletjohn, thanks for the reply. We do have heat proof board in place. There is an air gap of around 25cm either side of the stove to the heat proof board, and 5cm from the back of the stove to the

Oops, 2yo pressed send for me. 5cm from back of stove to heat proof board. So i was just wondering about paining the board. It looks ok as it is, but thinking about painting it to match the rest of the room. Do you know if the paint needs to be a special heat proof paint?

My heatproof board is painted with ordinary emulsion same as rest of the room. Been there two years and looks fine

If it's a heat-proof board I should think it won't be plasterboard, I don't know what they use.

water-based paints are less likely to soften or blister than oil gloss paint. So emulsion or a water-based gloss would do.

You will find the surface gets dirty due to air currents, so maybe not white.

Hi your set up sounds similar to ours we were advised to use fireproof paint but yish it's expensive unless you go for black. I used normal paint at our old house and it just used to crack.
