Versico’s CAV-PRIME Spray Gun is an industrial grade spray gun with a 3' extension nozzle for use with CAV-PRIME primers. The ergonomic handle makes it easy to spray and roll primer when used in conjunction with the CAV-PRIME Applicator Attachment Kit. The CAV-PRIME Spray Gun’s 3' extension is made from durable and rigid stainless steel for less flex when rolling primer. Note: Avoid cross contamination of CAV-PRIME and CAV-GRIP 3V/ CAV-GRIP PVC Adhesive in spray gun/equipment. NEVER USE LOW-VOC UN-TACK to clean CAV-PRIME Spray Guns or tips as it will cause primer to gel inside the hose/gun.
