The Easystar Dispensing System was specially designed to be used with Granastar “A” Grade granular pigments which create more intense and vibrant colors due to their high tinting strength. Plug the Easystar into a standard 120V outlet and into a compressed air source. Select the desired color, place the bag on the scale and press START. The Easystar will automatically bag the pigments quickly and easily. Using 4 primary colors to offer over 300 color blends, the Easystar automatically produces 1 bag of color for 1 yard of concrete. No programming required – just plug in, pick your color and hit the START button!
