Intumescent varnish fire retardant paint intumescent varnish intumescent paints

Protection of steel structures and raising of fire resistance category to class R/RE/REI _______ .

The application schedule involves the following phases:

1) Preparation of surfaces
Sandblasting to minimum finish of Sa 2 1/2 (SSPC-SP1O)

2) Primer application ( "a" or "b" depending on the substrate)
a) steel: application of our IDROSTAR in the amount of 150 g/m2 equivalent to a dry film thickness of approximately 40/50 mircon.
b) galvanized steel or other zinc-coated surfaces: application of our EPOXY PAINTRUST A + B antirust primer (dual component) in the amount of 150 g/m2 equivalent to a dry film thickness of approximately 50/60 micron.

3) FIREBLOCK®2000
Application of several coats, separated by the time intervals specified by the relative data sheet, of FIREBLOCK® 2000 intumescent paint in the quantity of kg/m2 to establish in accordance with mass and loading situations of the elements to protect and also in relation to the required degree of fire-resistance (R/RE/REI 30/60/90). The film thickness of FIREBLOCK® 2000 to apply is established on the basis of tabular or analytical assessment and determined by the reference engineering office, which must examine the project beforehand. The FIREBLOCK® 2000 can be applied by brush or by roller in the amount of 500 g/m2 per coat or by spraying in the amount of 700 g/m2 per coat (dispositive airless without filter with nozzle from 31).

4) Finish
When the FIREBLOCK® 2000 paint film is fully dry (after at least two days), the surface finish is completed by applying our chlorinated rubber finishing called STARGUM COLOR/E (satin version) or STARGUM EXTRA (glossy or semi-gloss version) designed to impart anti-weathering and water-resistant properties to the intumescent protection. The recommended quantity to apply in one coat is 150 g/m2 equivalent to a dry film thickness of approximately 50/60 micron.

For all information that aren’t present in this specification for the application, look at data sheets.

The cost of the entire schedule for the primer, intumescent coat and top coat (if required) is € _____/m2 with the exclusion of the application cost, scaffolding, sand blasting or preparation of the substrate.
The consumption for coat and the number of coats depend on the application system adopted and the steel structure to be treated. The painter is advised to check consumption personally and to keep strictly to the prescriptions of our engineering office.
