we are having a wood burner installed in our chimney breast, the inset or opening is all rendered and i want to know if i need to use heat resisitant emulsion if so where do i get it from, or is there another type of emulsion that i could use , ur help would be greatly apprteciated. cheers
I wouldn't have thought that the chimney breast would have got that hot! Not sure you really need to worry about it. I decorated a house with a woodburner in the living room a couple of years ago. Used emulsion on the chimney breast. No complaints thus far.
Rendering (even lime mortar) inside the fireplace recess does not survive very well due to the range of temperatures experienced. Try rosebery's suggestion and use ordinary emulsion - if the rendering crazes you've not lost anything.
Doh! Sorry didn't read the lead post properly. You mean INSIDE the opening.
Ordinary matt emulsion works over standard render with a gas spanish basket "hole in the wall" type fire but the woodburner will generate more heat.
In which case you may need to consider an intumescent paint. You can get these in gloss or eggshell finishes. Eggshell will be as close as you'll get to matt emulsion if thats what you are using on the rest of the walls. Virtually any RAL colour can be obtained so you can match the paint on the exterior of the chimneybreast.
Use your seach engine for intumescent paint to locate manufacturers.
nightscope, hi read your post. There should not be any trouble using an ordinary vinyl matt emulsion . The only problem you will get is the surface getting dirty, I would not use an intumescant paint as this is used for protecting steel in buildings and will exfoliate when heated (increase in thickness) which insulates the steel, not what you want on a flat wall and also being an oil based paint would be effected more than a water based paint.
True rosebery you can. but it’s a retarder not a protector, the finish contains small flakes of mica which with the special resins in the film expand when heated to protect the surface and also give of a flame retardant gas. Not something you would use on a surface that is not likely to catch fire. As we are talking about hot surface and not a surface that is likely to reach a flammable temperature, but I understand your thinking.
