Airless Sprayers atomize coatings by forcing the product through a small tip opening at very high fluid pressure. The fluid pressures range from 1200-3600 PSI. Airless sprayers are capable of spraying larger surfaces at higher speeds. Airless sprayers have more overspray than HVLP which is the amount of product that does not adhere to the surface you are spraying.
HVLP sprayers are classified as a finishing tool. The pressure from the cup supplies paint to the gun, where a high volume of low pressure air intersects with the paint stream breaking the paint into small particles called atomization. Since the spray pressures are much lower, the atomized paint has less bounce back. This means less overspray and better control.
The iSpray attachment, which will spray unthinned coatings including acrylic paint and stains, is ideal for big surface projects such as spraying walls, sheds, fences etc… It will provide a roller-like or slightly stippled finish.
The Standard spray attachment is your all-round attachment for a variety of paints and stains. It can be used both indoors and outdoors, where more control and a smoother finish is desired over the iSpray attachment.
When cleaning, use the appropriate cleaning solution (warm, soapy water for latex materials; mineral spirits for oil-based materials). Always check the back of the paint container for appropriate cleaning solution.
