PVA (Polyvinyl Acetate): A colorless, thermoplastic, water soluble, resinous high polymer
derived from the polymerization of vinyl acetate with a catalyst; used as a latex binder in certain,
generally lower quality water-base coatings.

PVA or drywall primers are inexpensive and high hiding. They provide a tight bond to new drywall, while providing a fairly opaque surface for your finish coat.
