Understanding Your Viscosity Meter

Using APOLLO-SPRAY viscosity meter is an accurate way of measuring the thickness/viscosity of a coating in order to ensure a fine finish.  The viscosity meter will accurately measure many different varieties of materials including, but not limited to, lacquers, sealers, enamels, stains, oils and waterbornes.

To Use:

  1. Dip the viscosity meter into the coating
  2. Start the stopwatch as soon as you pull the cup out of the material
  3. The coating will run out of the hole in the bottom of the cup in a steady stream
  4. As soon as you see the FIRST break in the stream, stop the watch
  5. The time showns is equivelent to #2 Zahn seconds
  6. Clean the cup and store


If the time you get is more than the recommended or desired time than you need to thin your material, use the appropriate thinner to the correct proprtion for your mixture.  Retest following each step again.  Continue to thin until the desired viscosity is reached or until you reach the maximum thinning recommended by the manufacturer of the coating you are trying to spray.
