Material Reduction/Projector Set chart

Before spraying, the material being used must be thinned with an appropriate solvent and the proper projector set must be installed. It
is always best to follow the material manufacturers recommendations and thinning procedures.
There are two simple methods of measuring the proper thickness of a material:
1. Dip a paint stick into the material and remove it, watching carefully as the material runs off. When the material begins to form
drops, the drops should fall about 1 second apart.
2. Use a viscosity cup (P/N 0153165). Dip the cup into the material and remove it. Use a watch or clock to time how long the
material drains from the cup in a continuous stream. Once the continuous stream breaks, stop timing and refer to the table below.
Add the appropriate solvent and continue testing until the proper thickness is reached for the type of material you are using.
