How to properly use and maintain the spray gun

Whether it is automatic paint machine, wood door paint machine and other painting equipment, or hand paint, must be used to spray gun, but the gun should be used before what should be done? Newly purchased spray guns are generally coated with anti-corrosion oil and must be cleaned before use. Remove the nozzle and clean it in a cup of thin material. This cup of thin material can be used after the retention of specially designed

. Carefully remove grease and metal debris from the threads of the nozzle and other parts. Fill the paint glass with half a cup of warm soapy water, then install it on the spray gun and shake hard to clean the paint cup and siphon. Spray soapy water with the spray gun and clean the inside lines of the spray gun. Finally, use nitro paint thinning or alcohol to wash away the soapy water can not wash off the dirt. When spraying with a gun normally, remember to wear gloves, respirators and operate in a well ventilated area.
: Experienced lacquerers can clean the spray gun with as little material or solvent as possible. Whether it's a gun sprayed with nitro paint or water-based paint, it can be cleaned with 1 ounce of thinner or water. Spraying the nozzle directly with a spray gun to clean the nozzle is a waste of material, and should be replaced with a soft brush after removing the nozzle. After repeated cleaning several times, dry the paint cup and pelvic cavity. After multiple cleanings, the material used for cleaning can become dirty and unusable, so remember not to pour the waste material directly into the sink or outside. If there is not much waste, the best way is to let it evaporate naturally, or you can spray it on the paint exhaust fan to vaporize it. Be careful not to allow the evaporative gas of flammable material to accumulate too much in the enclosed space to avoid explosion in case of fire.
