The application cycle provides the following procedures:
1) PREPARATION OF THE SURFACES
Check that the material to be protected is free of oily substances, grease, release agents which must be removed beforehand, and that the substrate is not already painted. Existing paint coats must be removed by sandblasting or by sandpapering.
Application of our product called PRIMER STARPLAST in the quantity of 100-150 g/m2 in order to improve the adhesion of the following coats of FIREBLOCK 2010/C.
3) INTUMESCENT PAINT
Application of several coats of intumescent paint called FIREBLOCK 2010/C with recoat time as specified in the relative technical data sheet. The dry film thicknesses and the quantities of FIREBLOCK 2010/C 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 2010/C 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 2010/C 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-bright or bright version) designed to impart anti-weathering and water-resistant properties to the intumescent protection. The recommended quantity to apply in one coat is 150-200 g/m2 equivalent to a dry film thickness of approximately 60 micron.
