  • Casting \ spread by brush or roller + stich roller to take air out.
  • For very large areas a spray with airless can be done,.

Thinning:

No thinning needed. To coat small areas it is required to make a suitable amount of mixture for immediate use. 

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.

Clarifications:

  • Storage room temperature 15°C to 25°C.
  • Over Spray: An effect which occurs in the spraying of paints application. A type of "dust" is created by dry gases of the air, which causing the paint particles to fall dry on the surface (hereafter the "effect"). The impact of this "effect" becomes stronger due to over pressure and heat, (most sprayers have a lever to control the   pressure) To avoid the negative impact 0f the "effect", the pressure of the spraying should be lowered to the necessary minimum!. Another possibility is to increase the amount of the thinner in the mixture which would cause the paint particles to fall wetter on the surface.
  • An additional recommended possibility, to avoid this "effect", is to add a retarder to the mixture which increases the duration period of the painting application , avoiding the paint to dry up, and enabling it to reach the surface wetter, Thus a better painted smooth  layer is formed.
  • Pot Life: The working time which is possible to paint a mixture of two components, A+B (or more) without spoiling the qualities of the paint or disqualifying the paint as "out of use".
  • Spray: It is possible to spray with a sprayer that has a container holding the paint that sprays it with air pressure.
  • Airless: a device with a piston which compresses the air for spraying paints. The pressure might be high (over 100atm.) Don't aim it at anyone
  • Surface preparations: the level of cleanness is determined by international standards. Surface preparations, including cleansing sand blasting, is important & critical factor in achieving an optimal result for painting adhesion on a certain surface. These standards are equally compared to the standards of the Swiss SA, the German-Din the U.S SSPC SP For each standard in any level there are indicators, for sale, in order to make visual comparison between the cleansing of the surface and the indicator.

Quality inspection:

  • Prior to the painting on large surfaces it is important to test the product on a small area, to be sure that the paint is compatible with the level of satisfactory.
  • Laboratory testing was made according to the standards institution specifications.
  • This "Data sheet" given as noncommittal information, the product above recommended for professional painting specialists. This information is not a substitute to personal guidance.
