Fireproof paste - characteristics and application

Proper fire protection should be performed at the initial stage of building. Thanks to it, it is possible to significantly minimize the risk of fire spreading inside them. A product that plays an important role in passive fire protection is the fireproof paste. What is it characterized by and what is its application? We will answer these questions in today's post. We encourage you to read.


Fireproof paste - what is it?


Generally speaking, the fireproof paste is a one-component water-soluble mass, applied with a tube applicator or putty knife. The product is made by dispersing two components - various types of pigments and synthetic resin. In the production process, the fire-resistant paste takes the form of a thick mass characterized by a creamy-white color.

The product can be applied classically with a brush or diluted with water. After drying, the fireproof paste has a high degree of flexibility. However, you should remember to prepare the surface properly, i.e. degrease, clean it and slightly moisten it with water.


The main and at the same time the greatest advantage of the fireproof paste is the high absorption of thermal energy and the creation of a special gas barrier responsible for the proper and long-term protection of the surface against open fire on which it was placed.


Fireproof paste - what is it used for?


The main purpose of using fireproof paste is to thoroughly seal service penetrations against the fire of certain types of plastic and metal pipes and cables. It is intended for fire protection: mineral wool used as an insulating cover, mineral wool boards in mixed penetrations, as a filling of gaps and expansion joints in walls and floors or as a sealing of plasterboards or a filling between them (Flame Cabel Paste A). And fireproof protection of service penetrations through walls and floors of steel, copper and cast iron pipes without insulation (Flame Cabel Pasta I).
