Heat resistant plaster – when do you need it?

Nowadays on the market are available many different types of plasters, though usually we use in our apartments and houses a traditional gypsum plaster – in the vast majority of cases it will be more than enough as its’ temperature resistance is about 50 Celsius degrees maximum. This means that if you don’ t have a chimney breast or a fireplace in your apartment, you most likely don’ t need a heat resistant plaster.
On the other hand if you do have at least one of the aforementioned structures, you will have to use a heat resistant plaster, because standard gypsum plaster will surely crack and won’ t stay on the wall if consistently exposed to temperatures higher than 50 Celsius degrees( which in case of fireplaces and chimneys is a normal working temperature ).

Basically you should apply a heat…

Basically you should apply a heat resistant plaster in an area about 3 meters around the fire opening( in case of fireplaces – both traditional ones and casette ones )or on the whole surface of a chimney breast. Be aware that practically all manufacturers recommend that the maximum thickness of heat resistant plaster should not exceed 6 mm and it is also necessary to let the applied plaster dry for at least 3 days before applying any heat to surfaces covered by the plaster.
