Dust-Free Interior Painting: How Inner West Painters Protect Heritage Homes

By Alex Dzissah, Founder, AKD Painting

Dust-free interior painting does not exist. Dust-controlled does. It means sanding through HEPA-extracted tools, sealing the work area in plastic, isolating the air conditioning, and vacuuming at the end of every day so fine plaster dust stays in one room instead of settling through the whole house.

Is dust-free interior painting actually possible?

No painter can sand plaster without making dust, so any quote promising a dust-free job is promising something the work does not allow. What a good painter can promise is containment. Whether you end up with a clean repaint or a fortnight of grit on every shelf comes down to whether the dust was captured at the tool and kept behind plastic.

The honest version of the claim is dust-controlled. It is a measurable standard: extraction at the sanding head, a sealed work area, isolated air handling, and a vacuum clean at the end of each day. Ask a painter what they do at each of those four points before you compare quotes.

Why do Inner West heritage homes make so much dust?

Older Inner West housing stock is built from materials that break down into much finer dust than modern plasterboard. Terraces and Federation cottages through Newtown, Annandale, Leichhardt and Petersham commonly have original lath and lime plaster, hessian-backed wall linings, and deep decorative cornicing. Lime plaster powders rather than flakes. Hessian backing releases fibre alongside the dust. Ornate cornices and ceiling roses hold a century of accumulated grime that comes loose the moment a sander touches them.

There is more surface area too. A Victorian terrace in Stanmore has picture rails, deep skirtings, panelled doors and moulded architraves where a 1990s house has flat plasterboard. Every one of those profiles needs hand sanding, which is the hardest kind of dust to capture.

Age brings a second issue. Anything painted before 1970 is treated as lead-bearing until it is tested, and lead changes dust control from a housekeeping matter into a health one. We set that process out separately in our guide to lead paint in older Inner West homes.

What does HEPA dust extraction actually do?

A HEPA-extracted sander pulls dust through the abrasive disc into a filtered vacuum before it ever reaches the air. The sander is not a different machine so much as a connected one: perforated disc, hose to the vacuum, filter rated to capture very fine particles rather than blowing them back into the room. Brands like Mirka and Festool build their orbital sanders around this, and the extraction is the reason they cost several times what a hardware-shop sander costs.

It is not total capture. Hand sanding into a cornice profile, scraping flaking paint, and cutting out damaged plaster all happen outside the extraction. That is why extraction alone is not a dust strategy, and why the containment around it matters just as much.

When do painters seal a room in plastic instead of using drop sheets?

Drop sheets catch what falls, and plastic sealing stops what floats, so the two solve different problems. Canvas drop sheets over the floor deal with drips, splatter and the coarse debris of scraping. They do nothing about airborne dust, which is the part that ends up in a wardrobe two rooms away.

We seal a room in plastic when the prep involves machine sanding of walls or ceilings, when the house is occupied during the work, or when the room adjoins a kitchen, a wardrobe or a nursery. The seal is plastic sheeting taped across the doorway with a zip or overlap entry, plastic over any vents, and furniture wrapped and taped rather than draped. On a full interior it is done one room at a time so the household keeps the rest of the house.

Where the work is a light scuff sand and recoat on sound modern walls, drop sheets and masking are proportionate and plastic sealing is not. Charging for a full seal on a job that does not need one is padding.

Can you live in the house while it is being painted?

On most Inner West interior repaints, yes, and the plan is what makes it workable rather than the equipment. The sequence we use keeps one room active at a time, finishes bedrooms early in the week so they are painted and aired before the weekend, and leaves kitchens and bathrooms for days when the household can work around them.

Timing matters more than people expect, and the room-by-room sequence is the main reason an occupied job takes longer than an empty one. We break down realistic durations in our guide to how long interior painting takes on Sydney homes.

What should you do before the painters arrive?

Four things from the household side make a bigger difference to dust than anything a painter brings on the truck. Take down soft furnishings that hold dust: curtains, cushions, bedding and rugs from the rooms being worked on. Turn ducted heating and cooling off for the duration of the prep, because a running system will distribute dust through the entire house within an hour. Empty or close the wardrobes in the active room. Plan around the sanding day if anyone in the house has asthma or a respiratory condition, or if there is a newborn at home.

Everything else is ours. Furniture that stays gets moved and wrapped, floors get covered, and the room is left vacuum-clean each evening rather than at the end of the job.

Which stage of an interior repaint is the dustiest?

Preparation, and specifically the sanding of filler and old paint on ceilings and cornices, produces almost all of the dust on a typical job. Ceilings are the worst of it because gravity is working against containment and because the areas are large. Once the surfaces are prepped, primed and ready, the dusty part of the job is finished.

Cutting in and rolling out the top coats generates effectively no dust. On a whole-house repaint that means the difficult phase is concentrated in the first stretch of the job, not spread through it. If you are planning to be away for part of the work, be away for the prep.

What AKD does on Inner West interiors

Our standard interior process is extraction at the tool, plastic-sealed rooms during prep, taped vents, wrapped furniture and a vacuum clean at the end of every day. We work through Newtown, Marrickville, Annandale, Leichhardt, Summer Hill and the rest of the Inner West, mostly on homes built before 1940.

Paint choice follows the same logic as the prep. We specify two-coat Dulux or Taubmans interior systems over the correct primer for each surface, because a controlled prep only pays off if what goes over it is worth the effort. The full interior scope is set out on our interior painting in Sydney page, and the heritage-specific detail on heritage and Federation house painting in the Inner West.

AKD Painting has worked across the Inner West since 2013, is Dulux Accredited, and holds a 5.0 star rating across 139 Google reviews. Every job is backed by a 5-year written workmanship warranty.

Frequently asked questions

Can you paint while we live in the house?

Yes, and most of our Inner West jobs are done with the household still in place. We work room by room, seal the active room, and hand back a clean, usable space at the end of each day. The rooms you need at night are scheduled so they are finished and aired before you need them.

How do you protect furniture that cannot be moved?

Heavy pieces are moved to the centre of the room, wrapped in plastic sheeting and taped closed, not just draped. Draped sheets let fine dust in at the sides. Floors get canvas drop sheets over plastic, and skirtings and architraves are masked before any sanding starts.

Will our ducted air conditioning spread the dust?

It will if it is left running. Ducted systems pull dust out of the work area and push it into every other room in the house. We tape the vents in the room being sanded and ask that ducted heating and cooling stay off during prep. Split systems in other rooms are fine.

Are HEPA-extracted sanders worth paying more for?

On an older Inner West home, yes. A sander plumbed into a HEPA vacuum captures most of the plaster dust at the disc rather than releasing it into the room. It costs more in equipment and consumables, and it saves a full day of cleaning on a whole-house repaint.

What is the dustiest part of an interior repaint?

Sanding back filler and old flaking paint, particularly on ceilings and cornices. That is the stage worth planning around. Cutting in and rolling the top coats produces almost no dust, so the back half of a repaint is much easier to live with than the front half.

Does dust control add to the quote?

The masking, plastic sealing and daily vacuum clean-up are part of our standard interior quote, not an extra line item. What changes the price is the amount of preparation the walls and ceilings actually need, which is assessed on site before anything is quoted.
