Hi all,
Hopefully a quick easy question, we have recently reopened our fireplace after it was blocked up, its now ready for the multi fuel burner to be installed however we would like to paint the interior first.
It is a concrete base with cement render, we are a little concerned if emulsion can take the heat or not, any thoughts?
The colour we are looking to use are preferably white for the base & a creme/coffee colour for the walls.

thanks in advance for your help

Ours is done in good old black vinyl matt , previously in blackboard paint , both have withstood the temperatures without problems ! ;)
Blackboard paint might be ok but you should use fireplace piant if the brick work is going to get hot.

Many others seem to have just emulsioned their bricks
Ah,Opps is right, I misread (it was late :oops: hic! ) Didnt realize you meant a fire, ours is just a log burner some 5 inches from the bricks

Thanks guys, it is a multi-fuel stove that's going in rather than an open fire, so hopefully the bricks shouldn't get too hot! We're really after a lighter finish than black, so might end up going for the emulsion than blackboard paint, etc...can't seem to find any tougher paints in anything other than black!
As the emulsion is water based it wont set on fire, it might discolour abit but if your using cream then it shouldnt be a problem. I painted my dads fire opening with white silk finish and had no problems. He had a stove inset aswell.
Don’t underestimate the amount of heat an inset multi-fuel stove can put into the immediate surrounding wall, that's why it’s best to have some form of surround, other than plaster. I have measured temperatures over 90 degrees C above & up to 80 degrees at the sides within 300mm of our multi-fuel stove at full tilt.

A sand/cement/lime based render is ideal where relatively high temperatures are involved but, hopefully, you’ll be OK. Gypsum plaster won’t stand much more than 50 degrees C & I wouldn’t use it within 500mm to the side or 800mm above the opening. You should be OK with ordinary emulsion but if you pick white, it will probably yellow fairly quickly.
Stovax do a fire place paint for what you want, in white or Black, but I was hoping for a cheaper alternative.
Radiator paint ?
Barry23 look at that last post date again, it's July -- 2010 :LOL:
^^ Appreciate that,

still like to know of any alternatives for myself, just about to install woodburner.

Got a fair bit of width either side, radiator paint any good on plasterboard ?

Don’t use Gypsum plasterboard (including Fireline) or plaster, it’s unsuitable for temperatures above 49 degrees, it will crack & fall apart.

Have a read of this lot;
As this comes up so often, I’ve put together this generic post; read the links but not all may apply to you.

You can DIY a stove install but you need to understand the Building Regs (which changed in October 2010), submit a Building Notice & pay a fee. Your LABC will inspect &, assuming everything is OK, issue a compliance certificate; the BI may want to witness smoke & spillage tests. No compliance certificate may lead to difficulties when you come to sell your property; if cannot produce a compliance certificate in the event of a problem, your insurance company may invalidate your policy & reject any claim.

Lots of archive threads on this, & other things you have to watch out for, here a few links for you to read: leaflet.pdf

& some more sobering just in case you think it’s all a load of old tosh:

Also get at least 3 quotes from local independent HETAS installers:

You might be pleasantly surprised & you should ask yourself if you really want all the hassle & risk getting it wrong; climbing onto the roof with an 8M stainless steel snake on your back is not for the feint hearted!
