Tech Tip: Viscosity & Needles

Most lacquers, urethanes, stains, varnishes and dyes do not require thinning with the Apollo models. Latex requires thinning to ensure a smoother finish and, depending on the type of latex, you may need to add approximately 10% − 15% water to the paint. To make it easy, a viscosity-measuring cup to ensure you have thinned the latex correctly.

Simply pour the latex in the viscosity cup to the level mark and determine complete drainage in seconds. If it exceeds the turbine rating of your unit, you will need to add water. Add one viscosity cup of water to your paint and mix well.

Retest; add more if necessary.
