Length - 05:21 Learn how to use a HVLP (High Volume Low Pressure) cup gun for staining interior and exterior concrete floors. The reason for using the gun at a high volume of material but with a low pressure is to cut down on airborne chemicals. The pressurized spray gun is primarily used with water-based stains and dyes when doing detailed coloring work on concrete surfaces. Acid stains are never used in the HVLP cup gun because the gun is made of metal. The corrosiveness of the acid would destroy the metal. Even when using water-based stains and dyes, be sure to properly clean the cup gun after each use. You can also use a traditional artists air brush for extremely intricate detailed coloring.
