Running a Plastering & Rendering Business in Australia
The builder says the house will be ready for render on Monday. Monday morning, your crew arrives to find the scaffolding is still up, the brickies are on the south wall, and the windows haven't been installed yet. Your three-person crew stands down for the day. $1,100 in wages, plus your time getting everyone there and back. This is the plastering business — brilliant when the site is ready, brutal when it isn't.
What a plastering business looks like
What plastering operators actually deal with
Multi-trade scheduling — you're last, and everyone delays you
Plastering and rendering sit late in the construction sequence. The brickies need to finish. The windows need to be in. The scaffolding needs to be in the right configuration. The substrate needs to cure. Each of these dependencies is controlled by someone else — and every one of them can independently push your start date out.
You can't control the sequence, but you can control how you respond to delays. The protocol: site readiness confirmation 48 hours before your scheduled start. Text or call the site supervisor the day before: "Confirming crew arrival at 7am tomorrow — is the site ready for plastering?" If they say no, you're not mobilising. If they say yes and it's not, you have a standing-down variation starting from 7am.
Weather windows — the scheduling complexity nobody outside the trade understands
Render application has temperature and humidity requirements. Too cold and the product won't cure correctly. Too hot and it dries before it can be properly worked. Rain within the cure period ruins the work. This makes scheduling render work in variable climate regions genuinely complex — and means planned work days frequently can't proceed.
Build weather delay clauses into contracts for external rendering work: "Weather conditions preventing application do not constitute a failure of the contractor's scheduling obligations. Rescheduling due to unsuitable weather is at the contractor's discretion and does not create an entitlement to accelerated performance." Builders who understand this don't call you demanding completion in conditions that will result in a failed product.
The "second coat is extra" dispute
You quoted "render and finish." The builder expected two coats. You meant scratch and skim. The product you used achieves the spec in one coat. Disputes about what "render" means are completely avoidable with a coat-system specification in the quote. "Supply and apply 2-coat acrylic render system: scratch coat (8mm) and texture coat (5mm)" has no ambiguity. "Render the exterior" has maximum ambiguity. Use the former. Always.
Where plastering margin gets lost
| Stage | What You Need | What's Actually Happening |
|---|---|---|
| Quoting | Coat system specified explicitly. Substrate preparation allowance and variation rate stated. Weather delay clause included. Site access confirmation process agreed. | Quote says "rendering." System not specified. No weather clause. Substrate prep not addressed. Standing down not discussed. |
| Job Management | 48-hour site readiness confirmation before mobilising. Standing-down events documented same day. Ambient conditions on application day recorded. Coat application progress photos. | Arrive to find site not ready. No documentation. No variation raised. Weather conditions on application day not recorded. Product fails — no defence. |
| Invoicing | Progress claim on major milestones (scratch coat complete, finish coat complete). Variations included with documentation. Weather delay time not charged but recorded. | Single invoice on completion. Variation for substrate prep not included. Builder disputes "second coat" not being in original quote. |
| Payments | Builder payment terms accepted and planned around. Materials procurement aligned with payment dates. Business line of credit to bridge. | 30-day invoice terms assumed but 60-day reality. Materials on credit card. Interest costs absorbed. |

Document it immediately and submit a variation the same day. Text the builder with the date, arrival time, what you found, crew size, and the day rate. Include it in the next progress claim. Consistent documentation changes builder behaviour — they start confirming site readiness before you mobilise rather than leaving you to discover the problem.
Build a substrate preparation allowance with a variation rate into the quote: "Additional preparation (filling, priming, sealing) if required: $X per sqm." When you arrive and find excessive porosity or preparation requirements, you have a pre-agreed rate. No surprise. No dispute.
Specify the coat system explicitly in every quote: "Supply and apply 2-coat acrylic render system: scratch coat (8mm) and texture coat (5mm)." When the system is defined upfront, there is nothing to dispute about what was included. The dispute only arises when the quote says "rendering" without specifying the system — which leaves every coat beyond the first open to interpretation.
