ADDITIONAL INSTALLATION BENEFITS USING A PRIMER.
In addition to MVB the thin coat of primer will seal in lock in place "Fish Eyes" and "Orange Peel" caused mainly by grease and oil embedded in concrete or plywood. Thus, allowing the next coat following day to roll out over fish eye and orange peel as if it was never there. This will also minimize any sanding needed from dust or debris left behind from Heppa Vacuum.

You will run the risk of bubbling, crater holes from out gassing concrete, and orange peel and fish eye regardless of how thick it is applied.
