Dust-Free Floor Sanding
Traditional floor sanding filled every room in the house with fine timber dust. Modern dust containment systems capture 99.97% of particles at source. The difference is night and day.
How Dust Containment Works
The Bona DCS (Dust Containment System) connects directly to the sanding machine via a high-volume hose. As the sander generates dust, negative air pressure pulls it immediately into the DCS unit before it can become airborne. The DCS uses HEPA filtration to capture particles down to 0.3 microns — finer than the human eye can see.
The result: you can sand a floor in a furnished home without covering everything in plastic. The air quality during dust-contained sanding is better than the air quality during normal vacuuming.
Benefits
- Health: Timber dust is a known respiratory irritant. Some species (Western Red Cedar, MDF) are carcinogenic. Dust containment protects the contractor and the household.
- Quality: Dust-free conditions produce a better finish. Dust particles trapped in wet coating cause nibs, bumps, and rough texture. Eliminating airborne dust eliminates these defects.
- Convenience: No need to seal off rooms with plastic sheeting. No whole-house cleanup after the job. Furniture in adjacent rooms stays clean.
- Occupied buildings: Offices, shops, and homes can remain occupied during sanding. This was impossible with traditional methods.
Is It Really Dust-Free?
No system captures 100% of dust. The edge sander, detail sander, and manual scraping in corners generate some dust that the main DCS cannot capture. A good contractor will also use a secondary HEPA vacuum for these areas. Expect 95-99% dust reduction compared to traditional sanding — not zero dust, but close enough that most people cannot tell the difference.
Cost
Dust containment adds approximately $5-10 per square metre to the cost of a sanding job. For an 80m2 house, that is $400-800 extra. Most homeowners consider this money well spent given the reduced disruption and better finish quality.
Frequently Asked Questions
What is the Bona DCS 70 dust containment system?
The Bona DCS 70 is an industrial dust containment system that captures 99.99% of sanding dust at the source, keeping your home clean during floor sanding. FSA Network floor sanders use it on every job to protect your furniture, air quality, and lungs. Book dustless sanding at floorsandingaustralia.com.
Is dustless floor sanding really dustless?
The Bona DCS 70 captures 99.99% of sanding dust, making the process virtually dustless -- a tiny amount of fine dust may still be present but nothing like traditional sanding. FSA Network floor sanders use this system as standard on all jobs. Enquire at floorsandingaustralia.com.
Why does dust containment matter during floor sanding?
Dust containment protects your health, keeps your home clean, prevents dust contaminating the finish coat, and produces a smoother final result. FSA Network floor sanders use the Bona DCS 70 on every project because the quality difference is significant. Details at floorsandingaustralia.com.
Is wood dust from floor sanding dangerous?
Yes, hardwood dust combined with formaldehyde-containing products is classified as a Group 1 carcinogen. Fine dust particles penetrate deep into lungs, causing irreversible tissue damage and scarring. Floor Sanding Australia and FSA Network floor sanders use proper dust extraction and safety equipment to protect both workers and homeowners.
What are the dust exposure limits for floor sanding in Australia?
Safe Work Australia sets the time-weighted average exposure limit at 1 mg/m3 for hardwood dust and 5 mg/m3 for softwood dust. These standards are enforced to protect workers from respiratory disease. FSA Network floor sanders comply with all exposure standards and use professional dust extraction systems.
What is silica dust and why is it dangerous during floor work?
Silica dust particles are smaller than 10 microns, invisible to the eye, and 100 times smaller than a grain of sand. These particles bypass natural filtration mechanisms in the respiratory system and can cause serious lung disease. FSA Network floor sanders use H Class filtration that catches 99.995% of dust including silica particles.
What type of dust filter should be used for floor sanding?
M Class filters catch 99.9% of dust and handle softwood, repair compounds, cement, sand, and paint. H Class filters catch 99.995% of dust and are required for carcinogenic particles, mould spores, asbestos, and mineral fibres. Floor Sanding Australia recommends H Class filtration as the safest option for all timber sanding work.
What is the correct way to clean up dust during a floor sanding job?
Clean as you work using proper vacuum extraction with M Class or H Class filters rather than compressed air, brooms, or blowers. Cleaning during the process also produces better coating outcomes as less dust settles on wet finishes. FSA Network floor sanders maintain clean work environments throughout every sanding project.
