Kool Ray is back by popular demand in its 'classic' Ezy-Off formula. Geat low cost shade paint that removes easily. Kool Ray Classic may be its new name but its formula is the original and reliable Kool Ray Ezy-Off. Kool Ray Classic is specifically designed to lower inside greenhouse temperatures during the warmer spring and summer growing seasons. During the course of the year, Classic's environmentally friendly ingredients will slowly wear off (weather permitting) allowing for increased light levels as the daylight decreases. Classic works best when spray applied.
How we tested: Kool Ray Classic was applied over standard greenhouse glass. Data was obtained through controlled laboratory findings and are intended as a guide only. The light source was fluorescent lighting measured 55" from the greenhouse glass. Light was measured in foot candles with a GE 214 light meter.
Many factors will affect actual shading density and light transmission in the field. The intent of the study was to provide a relative value of Classic's shading capacity for the grower to use as a reference only. Classic's shading density is influenced by other variables including accuracy in measurement & mixing of Kool Ray and application technique. Additionally, plastic glazing is translucent and has inherent light diffusing characteristics that should be taken into account when calculating shade requirements.

Dilution Ratios: Kool Ray is a super concentrated formula designed to be diluted with water. Standard dilution rate is 1 part Kool Ray to 8 parts water. Ratios can be adjusted according to the grower's particular needs. For a denser shade, several lighter, more diluted coats are recommended over a single, less diluted, heavy coat. A heavy coat can tend to cause "mud cracking" which can lead to eventual flaking and less even wear.
Coverage: Coverage will vary according to application, applicator, and dilution ratio. Spray will normally provide the best coverage of approximately 175 sq. ft. per gal. after dilution. Example: a standard 1:8 dilution of 1 gallon of Kool Ray Classic to 8 gallons of water yields 9 gallons of shade. A denser shade at a 1:5 ratio (1 gallon Classic to 5 gallons of water) yields 6 gallons. Multiply the diluted amount by 175 to determine coverage.
Time, Temperature and Wear: Best to apply in the morning above 50 degrees F (10 degrees C), after dew has lifted or late afternoon. Application within 12 to 24 hours of rain may result in premature wash off. Frost will also loosen shade. Residues on new plastic can act as a release agent causing lack of adhesion and wash off of Kool Ray Classic. A mist coat of classic over new plastic followed by a regular application has proven effective in promoting normal adhesion and wear. Application during hot, midday sun will tend to bake the shade more quickly, thus enhancing durability. In addition, plastic glazing heated by the sun and/or worn by the weather is more porous and will promote greater adhesion. Rate of wear is also dependent on weather conditions.
