INTUMESCENT PAINT FOR CORRUGATED SHEET METAL FLOORS WITH REINFORCED CONCRETE CASTING
It’s a water based intumescent paint for the protection of corrugated sheet metal floors with reinforced concrete casting. The product is certified in accordance with UNI EN 1365-2 standard.
The application cycle provides the following procedures:
1) PREPARATION OF THE SURFACES
Sandblasting to minimum finish Sa 2 ½ (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® 2024 with recoat time as specified in the relative technical data sheet. The FIREBLOCK® 2024 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 (airless device without filter with nozzle 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 2024 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.
