Polyflex Roof sealing 2K

Two component polyurethane 100% solids

A strong and flexible roof coating for coating bitumen, metal and concrete roof surfaces. Resistant to abrasion. The polyurethane resin provides a unique molecular structure which enable to fit the elongation and construction of the coating according to the extreme changes of the temperature and provides a perfect sealing against rain and moisture. Strengthen the existing infrastructure and provides a strong and smooth layer of coating which resistant to abrasion and suitable for car parking on roofs used as parking areas, for coating floors in public terrace . Suitable for filling and bridging gaps and cracks in bitumen. metal and/or concrete roofs. Has a self-leveling ability for an unlimited thick layer. Absorbs mechanical noise and hits.

Surface preparations:

  • Concrete roofs: sand with diamond stones under vacuum. Apply on absolutely clean surfaces. Spread epoxyden floor primer (see product application) in case the concrete absorbed the primer leaving crumbs applies another layer of Epoxyden floor primer. If surface wet apply an Epoxyden primer 450. For renewing: perfect cleaning, water high pressure cleaning 150 atm. min. and wait for drying. Sand with glass paper and vacuum.
  • Metal sheets roof: water high pressure wash, polyflex mastica on all metal contacts including screws.
  • Asphalt/bitumen roof: clean thoroughly with high water pressure in order to get an absolutely clean surface. Wait until the surface completely dries. Apply epoxyden primer water base- primer coat for this product.

Primer:

  • Dry concrete and metal sheets – epoxyden floor primer
  • Wet concrete – epoxyden primer 450
  • Bitumen – epoxyden primer water base or aquaflex.

Instructions:

  • Make sure that the base layer is dry, clean; dirt, dust and grease free.
  • Open carefully ‘A’ +’B’ sections of the Polyflex gag 225A and pour at the ratio 3:1 the required amount according to the volume = surface calculation for double layer coating.
  • Stir the mixture well with a slow mixer and immediately pour on the surface. With a large wiper or roller spread the mixture evenly on the entire surface. Spread on the entire surface with in 30 minutes, so it won’t harden and it won’t be possible to pout it while it is still liquid on the surface.

Packaging:

  • 4.5+13.5=18 liters.

Storage:

  • Store in a shaded place, at a temperature of between 15°C-32°C.with appropriate ventilation.
  • Keep lids tightly sealed.
