Intumescent varnish fire retardant paint intumescent varnish intumescent paints

Protection of steel structure and increase in fire resistance up to class R/RE/REI_______

The application procedure foresees the following phases:

1) Preparation of surfaces
Sandblasting to minimum finish Sa 2 ½ (SSPC –SP10)

2) Primer application on steel or galvanised surfaces
Application of 150 g/m2 of our EPOXY PAINTRUST (A+B), dual component antirust epoxy product, equal to a dry film thickness of about 50/60 micron.

3) FIREBLOCK® 2010
Application of several coats of FIREBLOCK® 2010 intumescent paint with recoat time as specified in the relative technical data sheet; the quantity (Kg/m2) to be applied must be established according to the massivity and loading situations of the elements to be protected and also in relation to the required degree of fire-resistance (R/RE/REI 30/60/90). The film thickness of FIREBLOCK® 2010 to be applied is calculated on the basis of experimental or analytical assessment by the engineering office of reference. For brush or roller application use 500 g/m2 per coat, for spray application (airless system without filter and nozzle size 31) use 700 g/m2 per coat (recommended quantities). It is important to pay particular attention to corners and angles where the product tends to accumulate. In this case spray from a greater distance and if necessary reduce the delivery of the gun.

4) Finish
When the FIREBLOCK® 2010 paint film is completely dry (after at least 2 days) the application procedure can be completed if necessary by applying our chlorinated rubber based STARGUM COLOR/E (satin version) or STARGUM EXTRA (glossy or semi-glossy version) top coat designed to impart anti-weathering and waterresistant properties to the intumescent protection. The recommended quantity to be applied is 150 g/m2, equivalent to a dry film thickness of approximately 50/60 micron.

For any information not mentioned above see the product technical data sheets.

The cost of the primer, intumescent paint and top coat if applied is €_________ per m2 excluding the cost of application, scaffolding, sandblasting or other preparation of the substrate.
The consumption per coat and the number of coats necessary depend on the application system adopted and the steel structure to be treated; the indication provided by our technical assistance service must be followed.
