Basic application instructions.
RUST DESTROYERｮ, RUST KNOCK OUTｮ
Brush, Roller, and Spray can apply both products. Our specification calls for a 3-mil dry film thickness. Since the solids by volume are 41% the WET paint to be applied is 7.5 mil. (1mil equals .0254MM). Please note if you do not get that thickness, the products will NOT work properly. To be sure that you have the proper thickness use a micrometer to measure mil thickness.
The following information was obtained form the industrial technical service group is for spraying
RUST DESTROYER ®, RUST KNOCK OUT ®
Equipment, airless spray with a 17 tip opening =. 017 in USA measurements, which equals 432MM. Using an airless spray at 2,500 to 3,000 PSI will atomize the products evenly.
For portability and easy use the equipment recommended is GRACO Ultramax ST 495 This is a portable unit for 1 and 5 gallon containers. But it MUST BE tested first. All you need is to be bale to plug into en electrical out let. This is the cheapest of the line. Cost approximately $ 2,073.00 Than you can look at the Ultramax ST 695, for $ 2,958.00 or Ultramax ST 795. for $ 3967.00 They all do the same thing. The higher the model number the bigger the machine, and the more heavy duty so it should last longer.
Also keep in mind that you lose coverage per gallon because of spraying. It is because you have wind, and the product will “bounce off” the surface. Additionally, some surfaces absorb more than others.
