INDUSTRIAL ROOFING – COLD – EXPOSED – STEEL

SPECIFIC WATERPROOFING SYSTEM FOR CARBON STEEL, CEMENT SUBSTRATE AND OLD COATINGS

• Substrate to be treated must be free from debris and dust. Clean the substrate by either water jetting or air blowing and/or brushing.

PRIMING:

DUROGLASS FF 4416 is 2 component solvent based modified epoxy primer for concrete, steel, wood, plastic and tiles old coatings, and the product can be applied in multi-purpose applications on a wide range of substrates. It has long over application time (15 days).
Can be applied by brush or airless spray as presented or diluted with 5-10% of Diluente 21, with consumption of 0,200 Kg/m². For airless application, use 0.015”-0.021” nozzles at a pressure of at least 180 bars.

WATERPROOFING MEMBRANES:

STARFLEX MONO TIX, (available also in the fire resistant grade, BROOF T4), one component thixotropic moisture curing liquid elastic polyurethane mem-brane, ready to use after mixing carefully with mixer at low r.p.m. Application can be done by roller or brush or airless, spray 45:1 or 60:1 (pressure 130-150 bar and nozzle 0,021” or adjustable). Roller application is necessary for rein-forced systems.
Consumption, even on vertical substrates is suggested at the maximum amount of 2,5 Kg/m2 per layer (without reinforcement), even though thicker layers are achievable. Roller application is necessary for reinforced systems.

Temperature of the product should be not lower than 20-22° C for spraying (best to check with a glass thermometer by dipping) otherwise the product could be too viscous. In cold environments mixing the product for 5 mins with a mixer can help rising the temperature of the product considerably.

REINFORCED SYSTEM: use STARTEX NW or GM and impregnate with two layers of 1-1,5 Kg/m2 each and embed on the fresh layer the reinforcement. STARFLEX MONO TIX allows also wet on wet application ot the second coat immediately with the same consumption of 1-1,5 Kg/m2. The second coat can be applied also the next day as soon as curing allows the system to be walked over. Consider dry climates to be slowing down the curing of the product.

Important notice – Having enough product on the substrate through the first coat application is mandatory for avoiding the falling of the reinforcement (NW) due to low stickiness of the substrate.

TOP COATS:

STARFLEX MONO TOP, one component elastic aliphatic polyurea based top coat for manual application at a rate of 0,15-0,60 kg/m² per coat. The product for anti-slip can be broadcasted with quartz on the first of the 2 top coats.
The product for anti-slip can be broadcasted with quartz.
When 2 coats must be applied do not let more than 48 hours between the coats.

STARFLEX MONO TOP 1, one component elastic aliphatic polyurea based top coat for manual application at a rate of 0,15-0,60 kg/m² per coat. The product for anti-slip can be broadcasted with quartz on the first of the 2 top coats.
When 2 coats must be applied do not let more than 48 hours between the coats.

  • Water vapour permeable, crack-bridging ability, resistant to immersion into water. Ideal for outdoor application. Can be over coated to improve U.V. protection, Solvent based.
  • Applicable from +5°C to 35°C substrate temperature (R.H. <85%).
  • Operating temperatures from -30°C to +80°C in air, (+200°C for short time).
