🎯 Key Takeaways: The “Invisible” Work Matters Most
If you think painting is just rolling colour on a wall, think again.
- The 80/20 Rule: 80% of a quality finish is plaster preparation; only 20% is the actual painting.
- New Plaster Danger: Never paint directly on fresh plaster. It needs a “Mist Coat” (diluted primer) to seal the surface, or the paint will peel.
- Crack Repair: Simply filling a crack isn’t enough. It needs to be “raked out” and taped to prevent it from coming back.
- One Team, One Bill: Hiring a combined plastering and painting team (like Golden Deco) eliminates scheduling conflicts and finger-pointing between trades.
Lumpy walls, visible patch marks, or paint that keeps peeling?
The problem is almost never the paint — it’s the prep. Our combined plastering and painting team inspects your walls for free and tells you exactly what’s needed for a flawless finish.
You’ve seen it before: a freshly painted wall that looks great from a distance, but up close, it’s a disaster. Lumps, visible patch marks, or paint flaking off in sheets.
The culprit isn’t usually the paint; it’s the plaster preparation.
At Golden Deco, we believe that a painter who can’t plaster is only doing half the job. Whether you’re renovating a heritage home in Hawthorn or a modern office, understanding the link between these two trades is the secret to a flawless finish.
1. The Foundation: Patching vs. Skimming
Not all repairs are created equal. Knowing the difference can save you money.
- Patching (The Quick Fix): Used for small nail holes, dents, or minor cracks. We use a high-grade filler (like Polyfilla or Spakfilla), sand it flush, and spot-prime it.
- Skimming (The “Brand New” Look): If a wall is wavy, rough, or badly damaged, patching won’t work. We apply a thin layer of “skim coat” plaster over the entire wall to create a glass-smooth surface. This is essential for high-gloss finishes or feature walls.
2. Fixing Cracks So They Don’t Come Back
A common DIY mistake is just rubbing filler over a crack. Within a month, the crack reappears. Why? Because buildings move.
Our “Pro Repair” Process:
- Rake It Out: We use a tool to widen the crack into a “V” shape. This removes loose debris and gives the filler more surface area to grip.
- Tape It: For larger cracks, we apply a self-adhesive mesh tape (fibreglass) to bridge the gap.
- Fill & Sand: We apply 2-3 coats of joint compound, feathering the edges out wide so the repair becomes invisible once sanded.
3. Painting New Plaster: The Critical “Mist Coat”
If you are dealing with a renovation extension or a brand-new build, painting fresh plaster is risky. Plaster is like a sponge—it sucks moisture out of the paint too fast, leaving the paint on top as a dusty, peeling layer.
The Solution: The Mist Coat
A “Mist Coat” is a sealer coat that penetrates deep into the plaster.
- For Plasterboard: We use a dedicated Sealer Binder or All-In-One Primer.
- For Solid Plaster (Brick): We use a specific solvent-based sealer (like Dulux PRECISION White Sealer Binder).
- The Golden Ratio: We often thin the binder by 5% with turpentine (or water for acrylic sealers) to ensure it soaks in deep and locks the surface.
Warning: Never use standard ceiling paint or PVA glue as a sealer. It will fail.
4. Special Care for Melbourne’s Older Homes
If you live in an older suburb (like Carlton or Kew), you likely have Lath and Plaster walls.
These walls are prone to crumbling and separating from the timber laths behind them. Standard patching often fails here. We use specialised “plaster washers” to re-anchor the plaster to the frame before skimming, ensuring your heritage walls remain solid for another 50 years.
Got lath and plaster walls in an older Melbourne home?
Standard patching fails on these walls within months. We use specialised plaster washers to re-anchor the plaster to the frame before skimming — so your heritage walls stay solid for another 50 years.
5. Why Choose a “One-Stop Shop”?
Traditionally, you hire a plasterer, wait for them to finish, and then hire a painter. If the paint looks bad, the painter blames the plasterer, and the plasterer blames the painter.
The Golden Deco Advantage: We do both.
- Accountability: If the wall isn’t smooth, it’s on us to fix it before we open the paint can.
- Speed: No waiting days for a separate trade to show up. We patch, sand, and paint in one seamless workflow.
- Cost: You save on call-out fees and administration by dealing with one team.
| Problem | The Cause | The Golden Deco Solution |
| Paint Peeling | Painting on fresh plaster before it was 100% dry or skipping the sealer. | We measure moisture levels first and use a specialized “Mist Coat” sealer. |
| Cracks Reappearing | Using standard filler without tape on structural cracks. | We “rake out” the crack and apply fibreglass mesh tape for a permanent bond. |
| “Flashing” | Painting directly over a patch without spot-priming. | We spot-prime every patch to ensure the sheen is consistent across the whole wall. |
| Bubbling | Trapped moisture or dust under the paint. | We vacuum walls before painting and use moisture-permeable paints for older homes. |
Conclusion: Smooth Walls Start Here
Don’t let poor preparation ruin your expensive paint job. Whether it’s a hairline crack or a full wall restoration, expert plastering is the secret ingredient to a luxury finish.

Frequently Asked Questions
Can I paint directly over new plaster?
No! You must wait for it to dry completely (1 week for thin coats, up to a month for thick render) and then apply a “Mist Coat” sealer. Painting too soon traps moisture and causes bubbling.
Do I need to prime patched areas?
Yes. Filler is more porous than painted walls. If you paint directly over a patch, it will look dull (a defect called “flashing”). We always spot-prime repairs before the topcoat.
How long does plaster take to dry?
Small patches dry in 1-2 hours. Skim coats take 24-48 hours. Solid render can take 4 weeks. We test moisture levels before painting to be safe.
Can you fix water-damaged plaster?
Yes, but only after the leak is fixed. We cut out the soft, water-stained plaster, replace it with water-resistant plasterboard, and seal it with a stain-blocking primer.
Why hire a plasterer and a painter separately when one team does both better?
No scheduling conflicts, no finger-pointing between trades. If the wall isn’t smooth, it’s on us to fix it before we open the paint can. Get a combined quote today.
