Is there a heat-resistant wall paint?

More and more people are heating with wood or pellets, the stove or fireplace is often in the middle of the living room. The heat of the fire is particularly noticeable in the immediate vicinity of the heat source, not every wall paint can handle it. Even the metal parts of the stove sometimes need a coat of paint: we'll go with you to find the perfect paint for heat-resistant surfaces.

Attention: normal emulsion paints are not heat resistant!

The regular emulsion paint from the hardware store is not the right choice when it comes to painting an area in the immediate vicinity of a heat source. However, cold zones on a chimney may be coated with it, but no area directly affected by the escaping heat.

Dispersion paints are not heat-resistant wall paints, a corresponding coating usually has cracks after some time and starts to peel off. This is due to the contained plastics, which deform from the heat and become porous in the long term.

How do I paint heat-intensive areas?

For the heat-intensive areas by the fireplace, there are special fireplace colors to buy, these paints based on mineral ingredients, more specifically on silicates. Minerals are heat resistant and will not change in any way when you heat up the fireplace.

The heat-resistant wall paint should be painted directly on the wall, never on an existing dispersion paint or on a wallpaper. Silicate paints adhere exclusively to mineral surfaces, in addition, a wallpaper or dispersion coating does not endure the heat anyway.

Use this paint to paint your stove

The named heat-resistant wall paint is however, as the name already says, only suitable for the wall or a wall. Metal parts on stoves are best protected by stoving lacquers, for a simple radiator lacquer these areas are too hot.

A prominent example at this point is a heat-resistant lacquer based on silicone resin, which can be sprayed on stovepipes and other parts. This type of paint can withstand temperatures well in excess of 500 degrees Celsius, making it ideal for painting your stove.

Tips & Tricks

Completely clear the chimney wall before painting with silicate paint so that a mineral base is available. Do not prime the surface with a base, but with potash water and do not apply gypsum-based putty. This keeps the coating reliable!
