The Hennes-Johnson HJ 6500 silicone sprayer is built for airless application of high-solids silicone, which is the hardest material most coating crews put through a pump. Direct immersion means the pump goes straight into the pail — no suction tube, no strainer to clog, no prime cycle to fight before you can spray. At 18,500 PSI output capacity, this unit handles even the thickest 100% silicone without thinning the material and compromising the finished roof.
Commercial roofing contractors choose the HJ 6500 when the job calls for silicone restoration coatings on existing low-slope roofs. It keeps pace with production crews and does not slow down on hot days when silicone thickens and lesser pumps start struggling. The bare unit configuration gives you the sprayer without hose and gun so you can match your own tip setup to the application.
