If you’ve ever walked into a room and looked up at a heavy, swirled Artex ceiling, you’ll know exactly why so many homeowners want it gone. It dates a space instantly. I’ve worked on homes across Melbourne where everything else was modern—but the ceiling still screamed 1985.
The good news is you don’t have to rip it out. Plastering over Artex is one of the most practical ways to achieve a clean, modern finish without turning your home into a demolition site. Done properly, it looks sharp, lasts for years, and saves a fair bit of money.
That said, this isn’t a slap-it-on-and-hope-for-the-best job. It comes down to preparation, timing, and technique. Get those right, and you’re laughing. Get them wrong, and you’ll be back at square one.
Before You Start: What Most People Get Wrong About Plastering Over Artex
Why You Can’t Just “Plaster Straight Over It”
This is where many DIY jobs go pear-shaped.
I’ve seen it more times than I can count—someone jumps straight in, spreads plaster over dusty Artex, and wonders why it starts peeling a week later. Plaster doesn’t stick to dirt, grease, or loose surfaces. It needs a proper base.
Think of it like painting over a dirty wall. It might look fine for a day or two, but it won’t last.
Key reasons plaster fails without prep:
- Dust prevents bonding
- Grease or nicotine stains block adhesion
- Sharp Artex peaks create uneven thickness
“A good finish starts long before the trowel hits the ceiling.”
When Plastering Over Artex Is the Right Choice (and When It’s Not)
Plastering over Artex is ideal when:
- The ceiling is structurally sound
- You want a quick cosmetic upgrade
- You’re avoiding the cost of removal
However, if the ceiling is sagging or cracked, plaster alone won’t fix it.
In older Melbourne homes, especially those with lath and plaster ceilings, I’ve often recommended overboarding instead. It’s a bit more work upfront, but it saves headaches down the track.
Safety First: How to Check for Asbestos in Artex Ceilings
How to Tell If Your Artex Ceiling May Contain Asbestos
If your home was built before the late 1980s, you need to stop and check.
Artex products used before the mid-80s often contained asbestos. There’s no visual clue—you can’t tell by looking at it.

What to Do If You Suspect Asbestos
In Australia, Safe Work guidelines are clear—do not disturb it unless you know what you’re dealing with.
When I worked on a renovation in a bayside suburb, we had an old ceiling that looked harmless enough. The homeowner nearly scraped it back. We tested it first—turned out it contained asbestos.
That decision saved a serious problem.
Checklist before proceeding:
- Arrange professional asbestos testing
- Avoid scraping or sanding
- Consider encapsulation (plastering over)
- Follow local regulations
Surface Preparation That Makes or Breaks the Final Finish
Cleaning the Ceiling Properly (No Shortcuts Here)
This is where the real work starts.
On one job in Brunswick, I skipped a proper clean early in my career. The ceiling had years of grime, and I thought, “She’ll be right.” It wasn’t. The plaster didn’t bond properly, and I had to redo the lot.
Lesson learned.
Cleaning steps:
- Use sugar soap solution
- Wipe down thoroughly
- Remove dust, grease, and stains
- Allow full drying time
Should You Scrape Artex Peaks?
If the texture is heavy, knocking back the high spots helps.
But—and this is critical—only do this if asbestos is ruled out.
A light scrape makes a big difference. It reduces how much plaster you need and helps create a more even base.
Applying PVA Bonding Agent the Right Way
This is the step that separates a solid job from a failure.
Basic PVA method:
- First coat: 1:3 (PVA to water)
- Second coat: slightly thicker
- Apply plaster when surface is tacky
If the PVA dries completely, you’ve missed the window. The plaster won’t grip as well.
Tools and Materials Checklist for Plastering Over Artex

Step-by-Step: How to Plaster Over Artex Ceilings
Step 1 – Mix Your Plaster to the Right Consistency
Getting the mix right is half the battle.
I always say it should feel like thick cream. Not runny, not stiff.
If it slides off the trowel, it’s too wet. If it clumps, it’s too thick.
Step 2 – Apply the First Coat (Base Coat)
Start small. Work in manageable sections.
Press the plaster firmly into the surface. The goal is to fill the texture completely.
It won’t look perfect—and that’s fine.
Step 3 – Wait for the Right Set Time
Timing here is everything.
Leave it too wet, and the second coat drags. Leave it too dry, and it won’t bond.
You’re looking for that middle ground—firm but still damp.
Step 4 – Apply the Second Coat for a Smooth Finish
This is where the ceiling transforms.
Apply a thinner coat and work in the opposite direction. It helps even everything out.
Step 5 – Trowelling and Finishing Touches
As the plaster firms up:
- Use a clean, slightly wet trowel
- Smooth out lines
- Polish the surface
This is where patience pays off.
Common Problems (and How to Fix Them Before It’s Too Late)
Plaster Cracking or Peeling After Drying
Cause: Poor bonding
Fix: Ensure PVA is tacky before plastering
Uneven or Lumpy Finish
Cause: Heavy Artex texture
Fix: Apply thicker base coat
Air Bubbles and Blisters
Cause: Rushing the process
Fix: Allow proper setting time
When Your Ceiling Needs More Than Just Plaster
Signs You Should Overboard Instead
- Sagging ceiling
- Cracks or movement
- Weak structure
What Is Overboarding and When to Use It
Overboarding involves fixing plasterboard over the existing ceiling.
In older homes around Melbourne, especially near the coast where moisture plays a role, this is often the better long-term option.
Real-World Example: Fixing a Rough Artex Ceiling the Right Way
A Typical DIY Scenario
A homeowner tries to plaster over a heavily textured ceiling without prep.
Result:
- Uneven finish
- Peeling patches
- Rework required
How a Proper Approach Changes the Outcome
On a similar job in St Kilda:
- Full clean
- Correct PVA application
- Two-coat plaster system
The result was a smooth ceiling that completely changed the feel of the room.

- Modern finish
- Adds property value
Final Tips for a Professional Result (Even as a DIYer)
A Simple Checklist Before You Start
- Test for asbestos
- Clean thoroughly
- Apply PVA correctly
- Mix plaster properly
- Work in sections
When to Call a Professional
- Large ceilings
- Structural issues
- No prior experience
Sometimes it’s worth getting a pro in. Saves time, stress, and rework.
Plastering over Artex is one of those jobs that looks simple on paper but demands attention to detail. Done right, it transforms a room completely. Done poorly, it becomes a headache.
From my experience working across different homes, the biggest difference always comes down to preparation. Take your time, follow the process, and don’t cut corners.
At the end of the day, a smooth ceiling isn’t just about looks—it changes how a space feels. And once it’s done properly, you won’t have to think about it again for years.
