What is Dunham PVA Drywall Primer Sealer
-
It’s a latex-based PVA (polyvinyl acetate) primer/sealer designed for interior drywall surfaces.
-
It seals new drywall, joint compound, and porous surfaces before painting.
-
It helps ensure a uniform base for paint — improving paint adhesion, reducing absorption, and preventing uneven sheen or blotchy finish.
✅ Common Uses / Where It’s Best Used
-
New drywall installations — after taping, mudding, sanding; before applying paint.
-
Drywall repair patches or skim-coated walls — to seal repaired areas before painting.
-
Unpainted drywall surfaces in renovation/ remodels — prepares drywall for finishing.
-
Ceilings and walls in residential & commercial interiors — ensures even topcoat finish and paint performance.
-
Drywall with heavy textures or porous areas — helps paint go on smoothly without excessive absorption.
Why Use a PVA Primer/Sealer Before Painting
-
Seals drywall dust, joint compound, and porous paper — prevents uneven paint absorption.
-
Improves paint adhesion and durability — prevents peeling or early wear.
-
Ensures uniform color and sheen on finish coat — avoids blotchy or patchy look.
-
Reduces paint consumption — because primer fills pores and reduces paint soak-in.
-
Allows quicker, cleaner paint project — fewer coats needed for even coverage.
⚠️ What It Should Not Be Used For
-
Exterior surfaces — this is an interior-only primer/sealer.
-
As a waterproofing or heavy-duty sealer for moisture-prone areas (bathrooms, basements) — it's not meant for that.
-
On surfaces requiring specialized primers (e.g. metal, glossy surfaces, mold/mildew-resistant coatings) — those need special primers.
