Using Latex (Emulsion) Paint
Although your turbine spray system is best suited to spray Class A Finish coatings such as lacquers, enamels, urethanes,
varnishes, waterborne and water base etc., you can spray latex (emulsion) house paint if you follow a few simple rules.
First
, it
is generally necessary to thin latex (emulsion) paint. This will vary from as little as 10% to as much as 50% depending on the
model turbine you are using and the quality of the paint used. Second, it is necessary to use a larger nozzle and needle set
in the spray gun (1.8mm, 2.0mm or 2.5mm). It is recommended that a latex (emulsion) paint conditioner like Floetrol®, be
added to aid flow-out. These products are sold at local paint stores.
