  • 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.
