Plastering and Rendering SWMS: Voids, Scaffold and Silica in Render

Internal plasterers often get off fairly lightly when it comes to high risk construction work, but not always, and renderers are a different story. Stairwell voids, high ceilings, exterior scaffold and silica in render compounds all need to be in a SWMS (Safe Work Method Statement) before work starts. Here’s what a plastering and rendering SWMS must cover.

When does plastering or rendering need a SWMS?

A SWMS is legally required when the job includes high risk construction work. For plasterers and renderers that commonly includes:

• a risk of a person falling more than 2 metres: stairwells and voids, high and raked ceilings, upper floors, and exterior scaffold
• work likely to involve disturbing asbestos, like old fibro walls and textured ceilings in renovations
• work on or near energised electrical services, such as hidden cables in walls and ceilings
• working where powered mobile plant is moving, like EWPs, telehandlers and other trades’ plant on site

If none of these apply, for example ground-floor plasterboard work with low ceilings, a Risk Assessment (some people call it a JSA) may be enough. Many builders still ask for a SWMS on every job, though, and it’s the first document a WHS inspector asks for on site.

Working on a site where someone else’s excavator, bobcat or other plant is operating? That’s still high risk construction work for your business, even though you’re not operating it. See working near someone else’s plant.

Stairwell voids: the one that catches plasterers out

A builder found us recently after his apprentice fell through a stairwell void. He’ll be fine, but WHS inspectors were on site not long after the ambulance left. Voids are a real risk for plasterers too, because plastering happens right when voids are at their worst:

• Void covers and guardrails get moved to get sheets in, or to plaster the stairwell walls, and not put back.
• Plasterers work on trestles and platforms right next to the void, looking up at the ceiling, not down at the edge.
• Stairwell walls and ceilings are often the highest work on the job, so falls can be serious.

Your SWMS should cover how you’ll keep voids protected: never removing a cover or guardrail without the builder’s OK, putting it back straight away, and using a proper working platform with edge protection for stairwell work.

Rendering: scaffold and silica

Renderers face a lot more high risk work than internal plasterers. Exterior rendering is usually done from scaffold, and many render compounds contain crystalline silica.

Working from scaffold

• Only use scaffold that’s been tagged and handed over by the scaffolder, and check the tag every day.
• Don’t remove ties, planks or guardrails to get closer to the wall. If something is in the way, ask the scaffolder to adjust it.
• Keep wet render and slurry off the planks to stop slips, and don’t overload bays with bags and buckets.
• Falling objects: keep tools and materials secured, and keep the area below barricaded.
• Your SWMS should cover using the scaffold. The scaffolder’s SWMS covers erecting it. See the scaffold example on our carpentry and builders SWMS page.

Check your render compounds for silica

Many cement-based renders, sand renders, texture coats and some patching compounds contain crystalline silica. Silica dust is created when you mix dry powder, grind or sand render, cut blocks or AAC panels, or chase walls, and it causes silicosis and lung cancer.

• Check the safety data sheet (SDS) for every product. Since 1 September 2024, materials with at least 1% crystalline silica are covered by the silica rules in Queensland, NSW and most states, and Victoria has its own silica rules.
• If the work is high-risk processing, you need dust controls, silica training for workers, and the right respirators. For construction work your SWMS can cover the silica controls.
• Mix carefully: add water first, pour powder low and slowly, mix outdoors or with ventilation, and wear a fit-tested P2 respirator while mixing.
• Grinding and cutting: on-tool dust extraction with an H-class vacuum, or wet methods, plus respirators.
• Wet render is also alkaline, so protect skin and eyes from cement burns.

More detail is in the silica section of our plumbing SWMS guide.

What a plastering and rendering SWMS needs to cover

Hazard	Controls to include
Voids, stairwells and open edges	Covers and guardrails kept in place (builder’s OK before any are moved, and put back straight away), and proper platforms with edge protection.
Trestles, planks and platforms	Correct trestle and plank set-up, platforms rather than ladders for ceilings, guardrails where a fall could exceed 2 metres, and care with stilts.
Scaffold	Tagged scaffold only, no alterations, keep planks clean, load limits, and falling object protection.
Silica in render and compounds	Check the SDS, dust controls, silica training, fit-tested respirators, and H-class vacuums.
Sanding dust	Dust extraction sanders, ventilation, P2 respirators, and wet clean-up rather than dry sweeping.
Overhead sheets and ceilings	Sheet lifters, two-person lifts, and rotating overhead work to avoid shoulder and neck injuries.
Manual handling of sheets and bags	Deliveries placed close to where they’re needed, trolleys and team lifts, and care on stairs.
Hidden electrical cables	Check before screwing or cutting into walls and ceilings, treat wiring as live, and RCD-protected tools.
Asbestos in renovations	Identify before you cut or sand, and assume it’s asbestos if unsure.
Render mixers and cement burns	Mixer guards, secure footing, gloves and eye protection, and washing wet render off skin straight away.

Make your SWMS work on site

• Read it and talk it through with the crew before work starts, then everyone signs. It isn’t a “tick, flick and sign here” exercise.
• Make it site-specific: these voids, this scaffold, these products.
• Keep it on site with the SDS for your products, and review it when the job changes.
• Give a copy to the builder before work starts. If there’s a principal contractor, it’s your responsibility to provide your SWMS before the high risk work begins.

How we can help

SWMS Done For You: $240. Tell us about the job, whether it’s plasterboard, ceilings, commercial fit-outs or exterior rendering, and we write a SWMS that fits your work, including voids, scaffold and silica controls. It arrives as a Word document within about 2 business days, ready to review, talk through, sign and take to site.

Plastering SWMS questions

Do plasterers need a SWMS for every job?

Only for jobs with high risk construction work, such as working near stairwell voids or high ceilings with a fall over 2 metres, asbestos in renovations, or exterior scaffold. Ground-floor plasterboard with low ceilings may only need a Risk Assessment, but many builders ask for a SWMS anyway. More on when you need a SWMS.

Can I move a void cover to get my sheets through?

Only with the builder’s OK, and it must go straight back. Better still, plan sheet deliveries and access so covers and guardrails stay in place. Your SWMS should say how voids will be protected while you work.

Does render contain silica?

Many cement-based and sand renders, texture coats and compounds do. Check the safety data sheet for each product. If it has at least 1% crystalline silica, the silica rules apply when you mix, grind, sand or cut it.

Can I adjust the scaffold to get closer to the wall?

No. Only the scaffolder should alter scaffold. Removing ties, planks or guardrails can make it unstable or leave open edges. Ask the scaffolder to make the change and re-tag it.

Does the builder’s SWMS cover my plastering work?

No. The business doing the high risk work prepares the SWMS for that work. As the plastering or rendering contractor, you’re responsible for your SWMS, and you must give a copy to the builder (principal contractor) before work starts.
