This class is for those who are thinking of getting a spray system or those who need help with their current spray system. Students will learn what’s important to know before purchasing spraying equipment and the information every sprayer has to know to master a perfect “off the gun” finish. Turbines and compressed air are the two main air sources, but there are several spray guns to consider. There are three sources of fluid delivery to consider. The viscosity of the material being sprayed needs to match up with the spray gun parts, fluid needles, fluid nozzles and air caps. How does one check for the viscosity of the material to be sprayed? Once spraying begins it is important to measure how thick or thin the coating is on the wood. Temperature and humidity greatly affects how well coatings will spray and cure, so a variety of coatings will be discussed. Gun maintenance will also be covered in detail. By the end of the day, participants will be much more confident in how to choose and use spraying equipment.
