Viscosity Viscosity is the technical term used to indicate the liquidity (thickness or thinness) of the material to be sprayed. Viscosity is measured in the number of seconds required for the material to pass through a Viscosimeter. This Sprayer can spray materials with a viscosity ranging from 10, to a maximum of 60. Material with a higher viscosity can be used only with water-soluble products (outdoor and indoor wall applications). Use high quality products.
