Wait time period between layer applications: 6-24 hours. (Finger test, figures change according to the temperature).

Ventilation: Work in well ventilated areas..

Application methods:

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


Thinner XL as needed. Better not more than 5-10%.  

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.


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


  • Make sure that the base layer is dry, clean; dirt, dust and grease free.
  • Open carefully the Polyflex gag and pour the required amount according to the volume = surface calculation for double layer coating.
  • Stir and add thinner XL. 5-10% and spray with pneumatic airless.

  • Don’t mix the product with materials which were not recommended by us.
  • Don’t apply if the temperature is under +7oC.

  • The recommendations listed do not hold any responsibility for this product.
  • Theoretical and actual coverage area are different concepts, the actual coverage is affected by the required thickness of the layers, required number of layers, painting conditions including the amount of paint which spread in the air before touching the surface.
  • The information listed in this section is based on experience and accumulating data, Denber inc., has the right to change the information listed at any time.
  • Paints that have been in stagnation or exposed to air more than needed could have their qualities changed.


  • Storage room temperature 15oC to 25oC.
  • 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.
