Storing equipment. While some manufacturers suggest a daily deep cleaning of the equipment, others suggest cleaning select parts daily while imposing a weekly maintenance schedule. If following a weekly deep clean schedule, it is critical to properly store paint daily.
"For overnight storage of larger trucks, completely fill the paint tanks with paint," Villani says. "To prevent paint from drying on the surface pour ½ gallon of water on top of the paint after the truck has been parked. Check for skins on the paint in the tanks each day before starting, and if the skins are present be sure to remove them before turning on the agitators."
According to Villani, if using heat exchangers. "It is necessary to turn off the heated glycol to heat exchangers about 10 minutes prior to the daily shut down thus allowing paint to cool the exchange," Villani says.
If using heat exchangers contractors need to weekly flush water through the heated hoses, exchanger and out of the paint guns. They will also need to clean the strainer at the discharge end of the heat exchanger. This system should then be recharged with paint.
A few reminders. Contractors should be aware of several additional tips when running their striping equipment. "Never run tanks dry," Villani says. "An empty tank allows air into the system causing a 'tree ring effect' inside the plumbing. After this happens several times, the system will need to be torn down and completely cleaned."
Villani says contractors can prevent this from happening by reloading tanks and pumping paint through the entire system until it's full.
Properly cleaning striping equipment will help extend its life. "Cleaning the equipment helps prolong the life of the fluid section along with the guns, tips and hoses," Heine says. "Cleaning your equipment is a very important procedure, not doing so can lead to increased downtime and wasted labor, material, equipment and money.”
Some manufacturers suggest contractors clean their equipment daily while others have a unique daily, weekly and monthly maintenance plan. Regardless, it is essential that contractors properly clean their equipment to maintain quality equipment.
