Information about heat resistant plaster
Generally speaking a heat resistant plaster is a replacement for usually used gypsum plaster everywhere, where the temperature is supposed to exceed 50 degrees centigrade: chimney breasts, fireplaces, etc. Due to the fact that on the market nowadays are available plasters from many different manufacturers, you will most likely have no problem with finding one that meets your demands( or meets the demands of a place, where it will be used ).
If, however, you need to know how such heat resistant plaster works and how it should be applied, read on for some basic info on that.
When comes to the structure, heat resistant…
When comes to the structure, heat resistant plaster does not differ from a gypsum one: it is a powder, which has to be mixed with water in precise proportions to form a paste( similar in consistency to a sour cream ), which is then applied to a wall or chimney breast and then left for some time to harden. As you surely know every type of plaster can be worked with some tools and in many cases specialists use sandpaper to polish the surface to a required smoothness.
It is important to remember…
It is important to remember that a heat resistant plaster should not be applied thicker than 6 milimeters on the wall. Another thing to be aware of is that if you apply a heat resistant plaster around the fire opening of a fireplace, you have to cover an area of about 3 meters – only then the surface will not crack and plaster will stay on the wall.
