Winter downtime is the right time to take care of sealer applicators

Equipment Maintenance

Open the recirculating valve to release pressure in the system and to allow material to recirculate. Leave this valve open throughout the winter.
When flushing the system with raw sealer and then water, open the hand wand and spray everything back into the tank.
Check hoses for scars, scuffs, or breaks and replace if needed.
Check oil on pump leathers. Many contractors wait to replace leathers, but waiting usually means operating for a while with a pump that’s not as efficient as it could be. Then you end up with downtime replacing the leathers when you could be out sealcoating a parking lot.

Once contractors have ceased sealcoating, the most important thing they can do is take care of the sealcoating equipment that has been so productive for them all summer.

“Cleaning and inspection is the single most important thing a contractor can do,” says Gordon Rayner, president of Rayner Equipment Systems. “Be it a paver covered with a season of asphalt particles or a sealcoat machine covered with splattering, they all need to be cleaned to see what you really have.”

Rayner says that more than just being unsightly, dirty sealcoating equipment hides problems that need to be taken care of, including worn bushings, chains, cracked brackets, leaking hydraulics, and chaffed hoses.

  “Pretend your equipment is an airplane and you are betting your life on its condition,” Rayner says. “It’s not an airplane but as a contractor you are betting your business on the performance of your equipment, so clean it so you can see it.”

Once the equipment has been cleaned he suggests a full inspection, complete with written notes, to inventory any problems and the condition of each part of the unit. Then make any and all repairs necessary.
