Factors Affecting The Cost Of Plastering
Several factors influence plastering costs, making it essential to consider these when budgeting for a project.
1. Type Of Plaster
Different plaster types have different prices based on materials and application methods.
- Gyprock (Plasterboard): Affordable and commonly used for interior walls and ceilings.
- Wet Plaster (Solid Plastering): More expensive but provides a smooth, seamless finish.
- Lime Plaster: Traditional and breathable, ideal for heritage homes but costly.
- Cement Plaster: Suitable for external walls, offering durability against weather.
- Acrylic Render: A premium option with enhanced durability and flexibility.
2. Surface Condition And Preparation
Before plastering, the condition of the surface impacts the overall cost.
- Damaged walls requiring repairs before plastering will add costs.
- Stripping old plaster increases expenses due to labour and disposal fees.
- Priming or sealing walls before plastering may be necessary, adding $5 to $15 per m².
3. Labour Costs
Labour is one of the largest expenses in plastering, with costs varying based on experience and location.
- Experienced plasterers charge higher rates but deliver better quality.
- City vs. rural rates: Plastering in major cities tends to be more expensive than in regional areas.
- Complex projects (ceilings, ornate designs) require specialised skills, increasing labour costs.
4. Size And Complexity Of The Job
Larger areas typically have a lower cost per square metre due to economies of scale. However, complex areas can drive up prices.
- Plastering a standard wall costs less than intricate decorative plastering.
- Ceilings require more labour, making them more expensive than walls.
- Curved or irregular surfaces demand more expertise, increasing labour costs.
5. Location And Accessibility
The location of the project affects plastering costs due to:
- Difficult access (high ceilings, stairwells) increasing time and equipment needs.
- Regional areas having fewer available tradespeople, sometimes resulting in higher rates.
- Inner-city projects potentially costing more due to parking and travel fees.
6. Additional Services
Some projects require extra services, impacting the final price.
- Painting after plastering: $20 to $40 per m².
- Decorative plaster features: $10 to $50 per metre for cornices.
- Soundproofing or insulation layers may add additional costs.
Conclusion
The cost of plastering in Australia varies depending on the type of plaster, labour rates, job size, and additional services required. Prices typically range from $10 to $100 per square metre, with labour costing between $40 and $80 per hour.
Preparing surfaces, choosing the right plaster type, and comparing multiple quotes can help homeowners and builders manage costs effectively.
Frequently Asked Questions
How Long Does Plastering Take?
The time required for plastering depends on the job size and complexity. A single wall can take a few hours, while plastering an entire home may require one to two weeks. Drying time also affects the timeline, with wet plaster needing several days to fully set before painting.
Can I Plaster Walls Myself?
DIY plastering is possible for small repairs or basic wall coverings, but achieving a smooth, professional finish requires skill and experience. Mistakes can lead to cracking, uneven surfaces, or costly repairs. For large projects, hiring a qualified plasterer is recommended.
What Is The Best Type Of Plaster For Bathrooms?
Bathrooms require moisture-resistant plaster to prevent damage from humidity and water exposure. Cement plaster or moisture-resistant Gyprock are ideal choices, ensuring durability and preventing mould growth. Regular plaster should be avoided in wet areas.
