INTUMESCENT PAINT FOR STEEL/GALVANIZED STEEL STRUCTURES
It’s a water based intumescent paint for the protection of steel and galvanized steel structures. The product is certified in accordance with EN 13381-8 standard.
The application cycle provides the following procedures:
1) PREPARATION OF THE SURFACES
Sandblasting to minimum finish Sa 2½ (SSPC –SP10)
2) ANTICORROSIVE PRIMER
a) On steel or galvanised steel surfaces, it is recommended the application of our dual component epoxy primer EPOXY PAINTRUST (A+B) in amount of 150 g/m2 equivalent to a dry film thickness of approximately 50 micron.
b) On steel surfaces, it is recommended the application of our one-component acrylic primer IDROSTAR in amount of 150 g/m2 equivalent to a dry film thickness of approximately 50 micron.
3) INTUMESCENT PAINT
Application of several coats of intumescent paint called FIREBLOCK 2018 with recoat time as specified in the relative technical data sheet. The dry film thicknesses and the quantities of FIREBLOCK 2018 to be applied shall be determined by the engineering office of reference: they are based on the required fire resistance class and of the technical data, relating to the profiles to be painted, contained in report of calculation and in the drawings.
The FIREBLOCK 2018 can be applied by brush or 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).
It’s important to take great care in the angled areas where the product tends to accumulate. Spray in this case at a distance of dispensing more high, reducing the scope of the gun.
When the FIREBLOCK 2018 paint film is completely dry (after at least 2 days) the application procedure can be completed, if necessary, by applying our chlorinated rubber topcoat called STARGUM COLOR (semi-gloss or glossy version) designed to impart anti-weathering and water-resistant properties to the intumescent protection. The recommended quantity to apply per coat is 150-200 g/m2 equivalent to a dry film thickness of approximately 60 micron. We suggest the application of one coat or two coats of STARGUM COLOR depending on the type of use.
