Description

HVLP spray guns are easier to use than most spray guns. It takes very little practice in order to spray with professional results thanks to the lower velocity. If you can use a paintbrush, you can spray with HVLP. Viscosity of coatings is important. Although we supply a guide, there is often some trial and error involved in arriving at the best viscosity. If a product is thinned too much, there are runs. Too thick and 'orange peel' or rough finish is the result. When thinning, it is essential to use a reducer that is compatible with the product you are using. To be sure, buy a thinner made by the same coatings company - always verify that it is the right product. It is wise to experiment on a practice piece to ensure that the finish is perfect. You may also request information from the coatings manufacturer - don't forget to mention you are spraying with HVLP equipment. Waterborne lacquers (acrylics, urethanes and varathanes etc.) can be applied successfully with HVLP. Most of these products require no thinning whatsoever. Many of these newer coatings contain a high-solids content of 30%-60% or more so the turbine must be powerful enough (at least the 3-stage). Several thin wet coats are preferable to one or two thick coats. Scuff sanding between coats is recommended. When spraying with HVLP, keep the gun at a constant 6" - 8" away from the project. Release the trigger at the end of each stroke. Then, depress the trigger and overlap the previous pass by about 1/3. Continue in this fashion for consistent coverage. Whenever possible, to reduce over spray to an absolute minimum you may use the Air Control Valve to reduce the volume/pressure of air passing through the spray gun. Turn the valve until the air is at the point where it is just barely atomizing the paint and yet the finish quality is still ideal. If the valve is turned too low, orange peel may result. There is a compromise here with setting the amount of paint sprayed and the size of the pattern. The Air Control Valve setting should be the last in the chain. In other words, decide on the viscosity and size of pattern first - then, you may find that you can reduce the air without affecting the quality of the finish.
