What Is Commercial Plastering?
Commercial plastering refers to the application of plaster materials on walls, ceilings, and other surfaces within commercial buildings such as offices, retail stores, schools, hospitals, and industrial facilities. Unlike residential plastering, commercial plastering typically involves larger projects and the use of specialised equipment and materials to meet the specific needs of the business.
The main types of plastering services used in commercial buildings are:
- Internal plastering: This is the most common type of plastering for internal walls and ceilings. It involves applying plaster on masonry, concrete, or drywall surfaces to create a smooth and durable finish.
- External plastering: External plastering is used to coat the exterior walls of a building. This may include rendering, which is a type of plaster applied to the outer surface of buildings to protect them from weather conditions.
- Acoustic plastering: This is a specialised plastering technique used to reduce noise transmission within commercial buildings. It is often used in offices, recording studios, and theatres to create soundproof environments.
- Fireproof plastering: In commercial spaces that require fire resistance, fireproof plastering is used. This type of plaster provides an extra layer of protection against fire hazards, especially in public spaces like schools, hospitals, and factories.
Factors Affecting The Cost Of Commercial Plastering
The cost of commercial plastering depends on several factors. These factors can have a significant impact on the final price, so it’s important for businesses to understand them when budgeting for their project.
Size Of The Area
The size of the area to be plastered is one of the primary determinants of cost. Larger spaces require more materials and time to complete the job. For instance, plastering an entire floor or a large retail space will be more expensive than plastering a small office or room.
Costs are typically calculated based on square metres, with plastering companies charging per square metre of wall or ceiling area. For example, the cost of plastering a standard office might be around $30 to $50 per square metre. However, prices can vary based on the factors below.
Type Of Plastering
The type of plaster used in the project plays a significant role in the final cost. Traditional plastering materials, like lime or gypsum plaster, may be cheaper compared to modern alternatives such as cement-based or fibre-reinforced plaster.
Plastering companies also offer different levels of finishes, such as basic, smooth, or decorative finishes. Decorative finishes, which include features like textured patterns or unique effects, can increase the cost of the project.
For example:
- Standard plaster finish: This is the most basic option and involves applying a smooth coat of plaster to the wall or ceiling.
- Smooth finish: A smooth finish requires additional steps, such as sanding and smoothing the surface, which increases the cost.
- Decorative finishes: Textured finishes or decorative plaster can significantly raise costs due to the extra labour and skill involved.
Labour Costs
Labour costs account for a large part of the total plastering cost. The complexity of the job, the skill level of the plasterers, and the time it takes to complete the project all contribute to labour costs.Plastering requires trained professionals, and the more skilled the tradesperson, the higher the hourly rate.
In Australia, plastering contractors charge between $50 to $80 per hour for labour, depending on their expertise and the location of the project. In major cities like Sydney or Melbourne, labour costs can be on the higher end of this spectrum.
In addition, if the project involves a large team or requires additional resources, the labour cost can increase accordingly. For example, a job that involves scaffolding, specialised equipment, or more than one tradesperson will generally cost more than a simpler, smaller job.
Location Of The Project
The location of the commercial building is also a crucial factor. Plastering costs can vary between regions in Australia, with major cities like Sydney, Melbourne, and Brisbane generally having higher rates than rural or regional areas.
The cost of living, local competition, and demand for plastering services can all influence pricing.In addition, the accessibility of the site may also affect costs. For example, if scaffolding is required to reach higher levels of a building or the building is in a congested area, additional costs will be incurred.
Type Of Surface
The type of surface to be plastered can also impact the cost. A smooth, even surface will require less preparation and result in lower costs. However, if the surface is uneven, damaged, or requires extensive repairs, additional work will be needed before plastering can begin, increasing the overall cost.
For example, plastering over rough brick or concrete walls may require more time and preparation, such as cleaning, priming, or patching up cracks, which can add to the price.
Time Of Year
The time of year can also play a role in plastering costs. Generally, demand for plastering services may be higher during peak construction seasons, which often coincide with warmer months in Australia (spring and summer). During these periods, plastering companies may charge higher rates due to increased demand.
On the other hand, during the off-peak season (autumn and winter), there may be more availability, and some companies might offer discounts or reduced rates to fill up their schedules.
Average Commercial Plastering Costs In Australia
While the exact cost of commercial plastering will depend on the factors discussed above, here are some average cost estimates based on recent market trends:
- Per square metre cost for internal plastering: The cost of plastering internal walls typically ranges from $30 to $50 per square metre for a basic finish. More elaborate finishes can push this price up to $70 or $80 per square metre.
- Per square metre cost for external plastering (rendering): External plastering costs, such as rendering, are usually more expensive due to the additional materials and preparation required. Prices typically range from $40 to $70 per square metre for basic rendering. Higher-end finishes, such as textured or coloured renders, may cost up to $100 per square metre.
- Acoustic plastering: For acoustic plastering, the costs can be higher due to the special materials and techniques involved. Costs for acoustic plastering typically range from $80 to $150 per square metre, depending on the thickness and soundproofing requirements.
- Fireproof plastering: Fire-resistant plaster is more expensive due to its specialised properties. Fireproof plastering typically costs around $70 to $120 per square metre.
Cost Breakdown Example
Let’s consider a medium-sized office space of 100 square metres requiring internal plastering. If the plastering is for a smooth finish, the cost would range from $30 to $50 per square metre, resulting in an overall cost of $3,000 to $5,000. If a more decorative or textured finish is required, the cost could rise to $7,000 or more.
Additional Costs
In addition to the costs of plastering itself, there are several other factors that could increase the overall cost of the project:
- Preparation work: If the surfaces require cleaning, patching, or priming before plastering, these additional costs should be factored in.
- Scaffolding: If scaffolding is needed for high walls or ceilings, this can add between $1,000 and $3,000, depending on the size of the building.
- Materials: While plaster is generally affordable, the type of plaster used can impact costs. Premium products or materials that offer additional benefits, like moisture resistance or fire resistance, can increase the overall cost.
- Finishing touches: Some commercial spaces require additional finishes such as mouldings, cornices, or other decorative elements, which can raise the final price.
Conclusion
Commercial plastering is an essential part of the construction and renovation process for many businesses, and the cost of plastering services varies depending on a variety of factors, such as the size of the area, the type of plastering required, and the location of the project.
When budgeting for a commercial plastering project, businesses should take into account both the direct costs (labour, materials) and any additional expenses (preparation work, scaffolding, finishes).
