C2 Wallboard Primer (L1800) - Drywall & Plaster Sealer

Plain-English overview: A fast-drying, low-odor acrylic drywall primer that seals new wallboard and cured plaster so your finish coats apply evenly and look uniform. It hides well, sands easily, and creates a consistent surface for any C2 interior paint.

Why choose it

• Seals fresh drywall to reduce porosity and prevent flashing.
• High hiding for joints, patches, and skim-coated areas.
• Fast turnaround: touch-dry in about 30 minutes; recoat in 2–4 hours.
• Low odor, low VOC; soap-and-water cleanup.
• Brush, roll, or spray with smooth sanding between coats if needed.

Where it excels

• New drywall/wallboard and dry, fully cured plaster.
• Previously painted interiors needing spot-priming or a full prime before light colors.

Coverage & key specs

• Covers: ~400–450 sq ft per gallon (don’t overspread—coverage affects hide).
• Dry time: Touch ~30 min; recoat 2–4 hrs; ready for finish coats the same day under normal conditions.
• Application temp: Apply only when product, surface, and air are above 50°F (10°C). Protect from freezing.
• Sheen: Flat for optimal topcoat adhesion and uniformity.
• Cleanup: Warm, soapy water.

How to apply (step-by-step)

1. Prep: Sand joints and patches smooth. Remove dust, dirt, and grease. Dull glossy spots; repair defects.
2. Stir or shake - do not thin.
3. Roll/Brush: We typically recommend a 3/8" nap (or larger) roller for new drywall and a quality synthetic brush for cutting-in. Load the roller well and maintain a wet edge.
4. Spray (optional): Airless tip 0.012"–0.015"; apply a uniform coat for consistent hiding.
5. Recoat/Topcoat: Allow 2–4 hours before applying your C2 Luxe or Studio interior finish.

Pro tips

• Let new plaster cure fully (about 30 days) before priming for best adhesion.
• If joint banding or flashing shows after the first coat, apply a second properly loaded coat rather than stretching coverage.
• For heavy stains (water, marker, smoke), spot-prime with a dedicated stain-blocking primer before using Wallboard Primer.

FAQs

Is this a drywall primer or a general interior primer?

It’s formulated for new drywall/wallboard and cured plaster, and it also works for spot-priming previously painted interiors.

Do I need to sand new drywall before priming?

Yes. Sand joints and repairs smooth, then remove dust. Proper prep improves hiding and topcoat uniformity.

Can I spray it?

Yes. Use an airless 0.012"–0.015" tip. Apply even coats and clean equipment with warm, soapy water.

When can I paint over it?

Under typical conditions you can recoat in 2–4 hours and finish the same day.

Does it block tough stains by itself?

It seals and evens porosity but is not a heavy-duty stain blocker. For severe stains, spot-prime with a dedicated stain-blocking primer first.
