Fireproof paste - properties and examples of technical application

Fireproof pastes are widely used in passive fire protection. This means that their task is to seal the protected surface in the installation penetration or expansion joint and prevent further spread of fire and heating of the fire barrier.


Carboline Polska offers fireproof ablation pastes, which are a water dispersion of resins and additives. They show excellent adhesion to the substrate made of various building materials. When applied to the appropriate thickness, the paste absorbs large amounts of thermal energy during a fire, and also releases a gas barrier, thanks to which it protects the surface for a long time. The application of the paste is quick and easy - you can use the spatula available at any construction site.


Fireproof paste is used primarily to protect mineral wool, plasterboard and connections of steel, concrete, bricks and boards. This material is widely used in the construction of combined, fire-resistant installation penetrations, as well as protection of joints and expansion joints. Fireproof paste can also be used to create a partition in combination with wool or plasterboards. A popular application of fireproof pastes is sealing expansion joints and installation penetrations of steel, cast iron and copper pipes, as well as cable bundles. In the event of a fire, these elements are particularly prone to rapid heating.


What are the other passive fire protection methods?


Passive fire protection ensures that even in the event of a fire, the building structure remains intact for as long as possible. It is therefore a good protection against serious damage, and above all material losses. It also protects against the development of fire, which often saves the lives of people in the building. Passive fire protection should be installed already at the construction stage. Their most popular and effective examples are:


  • fireproof intumescent coatings for steel structures,

  • fireproof pastes,

  • fireproof mortars that protect reinforced concrete structures,

  • fireproof coating with excellent thermal and sealing properties, used to protect flexible elements, e.g. cables,
