INTUMESCENT PAINT FOR REINFORCED CONCRETE/PRESTRESSED REINFORCED CONCRETE STRUCTURES AND FOR NOT LOAD-BEARING PARTITION WALLS IN BLOCKS OF BRICK AND CONCRETE
It’s a water based intumescent paint. The product is certified for the protection of reinforced concrete/prestressed reinforced concrete structures in accordance with EN 13381-3 standard; for the protection of non-load-bearing partition walls in blocks of brick and concrete in accordance with UNI EN 1363-1 and UNI EN 1364-1 standards.
The application cycle provides the following procedures:
1) PREPARATION OF THE SURFACES
Verify that the surfaces are clean and free from oily substances, grease and release agents. In the case of surfaces already painted, existing paint coats must be completely 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 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.
