How to Paint New Plasterboard

How to Paint New Plasterboard (Beginner Guide)

New plasterboard needs a specific process to look smooth and last long.
Here’s the beginner-friendly method.

1. Remove All Dust

Plaster dust stops paint from sticking.
Use:

• Brush

• Cloth

• Vacuum

2. Prime the Plasterboard Properly

Use:

• Sealer/primer

• Plasterboard-specific undercoat

Never paint bare plaster — it soaks up paint unevenly.

3. Let Primer Dry Fully

Dry primer feels smooth and chalky.

4. Apply First Coat of Wall Paint

Use long roller strokes.
Keep a wet edge to avoid lap marks.

5. Lightly Sand Between Coats (Optional)

Use 240–320 grit to remove small bumps.

6. Apply Second Coat

Two coats are essential for new walls.

7. Inspect Under Light

Shine a lamp sideways to check for missed spots.
