Description & use

Flame Stal® FireProof Solvent is a fireproof intumescent coating. One-component, thixotropic mixture based on organic solvents. Under the influence of high temperatures, Flame Stal® FireProof Solvent foams, creating a durable thermal insulation, delaying the temperature increase of the steel substrate. Flame Stal® FireProof Solvent is a fireproof intumescent coating intended for fire protection of steel and galvanized steel structures, made of open and closed profiles, in classes from R-15 to R-60 against thermal impact of standard fires according to PN-EN 1363-1: 2012. Flame Stal® Fire Proof Solvent coating has the Technical Approval ETA-20/0957 and the certificate of compliance FIRES-1396-CPR-0199. Fire-protected elements can be used inside and outside buildings under the influence of environmental factors Z1, Z2, X, Y and various environmental corrosivity categories from C1 to C5.

Flame Stal® FireProof Solvent is applied to surfaces previously protected against corrosion with a primer paint or to prepared galvanized surfaces. The Flame Stal® FireProof Solvent fire protection system creates a flexible and mechanically durable protection, resistant to moisture, condensation water and weather conditions, including industrial atmosphere. As an intumescent layer in sets with appropriate undercoat and topcoat paints, it is used for fireproof protection of steel structures with open and closed profiles working outside or inside objects, including galvanized surfaces. Before using the system, consult the technical advisor of the paint manufacturer or distributor. Fire protection may be performed only by trained companies that have received or have a valid Flame Stal® FireProof Solvent System Contractor's License. The product is intended for professional use.


In case of painting after assembly or when the structure is subject to periodic painting breaks  clean structure surface  of dust and loose contamination deposited during transport and assembly of elements. It is essential to remove all traces of grease. The thickness of the dry coating of the intumescent layer should be determined depending on the required fire resistance class of the object and the massiveness of the steel structure elements.  The massiveness U / A [m-1] is the ratio of the circumference of the heated element to the area of its cross-section. The thicknesses of the Flame Stal® paint are given in the relevant tables in the European Technical Assessment ETA-20/0957.

Unprotected steel

At a critical temperature of 500*C steel loses its strength.
Fire resistance ratings may be far less than 30 minutes.


Steel protected with intumescent coating

Typical application of Flame Stal® Fireproof Solvent by airless-spray.


Steel protected with intumescent coating in a fire scenario

Steel with an intumescent coating fulfills
the official test requirements for eg. 15, 30, 60 minutes.


Stored in
20 l buckets
