How Many Gallons of Primer for Bare Drywall?
Bare drywall requires polyvinyl acetate (PVA) primer, which covers approximately 250 to 300 square feet per gallon on raw drywall due to high paper and joint compound porosity. For a 1,000 sq ft drywall installation, you need between 3.3 and 4.0 gallons of PVA primer (purchase one 5-gallon bucket).

Why Bare Drywall Requires Dedicated PVA Primer
New drywall consists of porous face paper and absorbent joint compound (mud). Standard topcoat paint absorbs unevenly into these two different materials, causing "flashing" (patches where paint looks dull or blotchy). PVA primer seals both materials with an even synthetic polymer film, ensuring uniform topcoat sheen.

Ordering 6 total gallons covers all walls and ceilings with sufficient margin for heavily mudded taped corners.
Can I tint PVA primer?
Yes, tinting your primer to roughly 50% of your topcoat color improves hiding power dramatically when painting rich or dark colors.
