Seeding Primers & Blow Out MMA Primer Puddles

Many contractors (MMA & others) religiously seed primers with CQ sand or a 16/20 silica sand to facilitate a mechanical and chemical bond, especially but not limited to, hot temperature environments.

After blowing out primer puddles with the BroadastPro6 (see video below), fill the hopper and restrict the flow with the flow restrictor control arm, and turn down the RPM's on the throttle control arm (conveniently located next to the throttle arm for maximum, total control)  and lightly seed the primer.  

This action also helps to circulate air in small areas that are predisposed to dead air space that will inhibit the primer easily, creating costly time consuming problems to fix.
