When choosing a plaster for fireplaces and stoves, you need to consider that it must be resistant to high temperatures, its differences and perform a protective function. Now you can mix the solution yourself or buy ready-made high-quality mixtures in the hardware store, which are easy to use. Special, heat-resistant “Terrakot” or “Pechnik” plasters are used for leveling the surface of stoves, fireplaces, mangal zones, etc.
There are also decorative types of mixtures for facing the surface and giving it a beautiful look. Depending on the base, which is part of the finishing material, emit acrylic, silicate, mineral and silicone plaster.The so-called Venetian plaster is very beautiful, which in its texture and appearance resembles marble.
