Moving into a brand-new home is exciting — and the walls are one of the first things you notice. Yet many new Perth homes are handed over with a basic builder’s finish: thin coverage, visible joins or patchy colour once the light hits the walls at an angle.
If you are arranging your own painting, or upgrading the builder’s finish, here is what a proper new-home paint system looks like and why each step matters.
Why New Walls Are Different
New plasterboard and set joints are porous, and they absorb paint unevenly. The paper face of the board and the jointing compound soak up paint at different rates, so a topcoat applied straight onto bare plaster can look blotchy — a problem often called “flashing”.
That is why new surfaces need a dedicated first coat designed to seal and even out the substrate before any colour goes on.
Step 1: Inspection and Preparation
Before painting, the walls should be checked for small imperfections — dents, nail pops, rough joints or dust. Minor defects within scope are filled and sanded, and the surfaces are cleaned. Floors, windows, benchtops and fittings are protected.
Step 2: Sealer or Undercoat
The right sealer or undercoat is applied to suit the substrate. This coat:
- Seals the porous plaster and jointing compound
- Creates an even base so the topcoats look uniform
- Helps the finishing coats bond properly and last longer
Skipping this step is one of the most common reasons new homes need repainting sooner than expected.
Step 3: Two Full Finishing Coats
Two full coats of quality interior paint give consistent colour, proper film thickness and a finish that holds up to everyday life. One coat might look acceptable from a distance, but it rarely delivers even coverage or durability — especially in hallways, kids’ rooms and living areas.
When Should You Book Your Painter?
Ideally, contact your painter before handover. Many new builds can be quoted from plans, which lets you lock in timing so painting happens before furniture arrives. Painting an empty home is faster, cleaner and avoids moving everything twice.
Choosing Colours for a New Home
New homes in Perth often have generous natural light, so colours can read lighter and cooler than the swatch suggests. Test samples on several walls and view them morning and afternoon before deciding. Our guide to choosing interior colours has more tips.
Questions to Ask Your Painter
- What sealer or undercoat will you use on new plasterboard?
- How many finishing coats are included?
- Which surfaces are in scope — walls, ceilings, doors, trims?
- Are you a registered painter in WA?
- What happens if marks appear after we move in?

Frequently Asked Questions
Can I paint straight over new plasterboard?
Not if you want a professional result. Bare plasterboard needs a sealer or undercoat first so the topcoats dry evenly.
Do builders paint new homes properly?
Standards vary between builders and contracts. Many homeowners choose to upgrade to a fuller paint system for better coverage and durability.
How soon after handover can I paint?
As soon as the home is handed over and accessible. Booking before you move in is the easiest option.
