Making barbecues, chimneys, ovens, etc., requires using specific materials that withstand the extreme conditions to which they are going to be exposed (high temperatures, expansions and contractions, etc.).
The solution lies in using PROPAM® REFRACTARIO, a refractory mortar which, due to its technical characteristics, is suitable for coating walls and making joints that are subject to environments in contact with fire or high temperatures.
The abrupt changes in temperature that occur when lighting barbecues, fireplaces, ovens, etc., produce dilations.
When turning off facilities, contraction movements in the materials used are produced.
These changes can produce cracks and even lead to loosening, if the materials used for its realization, are not suitable.
PROPAM® REFRACTARIO is an assembly mortar, with high mechanical resistance that can withstand temperatures of 1200ºC.
Check the condition of the substrate, it must be completely set and clean of dust, paint, oils, etc.
If it is exposed to the sun or very absorbent, it is recommended to moisten it in advance.
Knead PROPAM® REFRACTARIO with a slow electric beater (500 rpm) to obtain a homogeneous mass free of lumps.
Apply the mortar with the aid of a pallete, respecting the application time that will be about 30 minutes.
The final finish of the joint can be profiled with the aid of a pointer.
- Apply between +5 ° C and +35 ° C.
- The mortar begins to harden in two hours, although it reaches its resistance after 24 hours.
- Withstands up to 1200ºC.
- Do not apply to plaster, paint or any disintegrable or non-absorbent surface.
