Last Updated May 3, 2016 · Written by Rob Schneider
Are you looking for a cost-effective way to give your home's exterior a new lease on life?
There are many practical and aesthetic benefits to rendering your home. It can help modernise old brick façades while helping to preserve and protect them from the elements. Render can also help add value to your home.
Top professional renovators put rendering high on their lists of ways to add value to a brick home. Most agree that rendering brick can add up to 10 times the cost of rendering to the sale value of a home. Renovation guru Cherie Barber considers rendering ‘compulsory’, especially for older properties with terracotta or blonde face brick.
But how much will it cost you?
This article will help you figure out:

What is render?
Traditionally, render is a mixture of sand, cement and clay that is spread over the surface of a wall to "render" or give it a smooth or textured. Advances in technology have seen other types of render developed, with more resistance to cracking. When getting quotes for your project, expect to come across these types of render:
- Cement render is a mixture of sand, cement and sometimes clay and/or lime. It can come pre-mixed or may be mixed on site. A newer version of cement render, polymer modified cement render, comes pre-mixed. While it costs more, polymer modified cement render is said to adhere better than cement render and because it can come in a variety of colours, may save you the cost of painting.
- Acrylic render is becoming increasingly popular because it resists cracking, which is a common problem with cement render. It can also be skimmed over the surface of a cement render, which may be a money-saving option if several layers of render are needed.
- Polymer-modified render is another type of cement render. The added polymers prevent cracking and help the cement adhere better.
- Bagging render is a coarse cement render that gives a rough look, and is the cheapest type of render
- Plaster is most suitable for indoor application because it is softer and slow-drying

Does my renderer need to be licensed?
Depending on where you live, your rendering professional could have a licence in a number of different disciplines, including painting, wet plastering, concreting or building. Check what applies in your state before you hire anyone.
Choosing a rendering service
As rendering becomes more popular, the number of rendering services is increasing and prices are coming down. However, the quality of render is going to make the difference between spending your money wisely and wasting it. When comparing rendering quotes
, cost is only one consideration. Other things to consider include:
- how experienced a service is
- the styles and finishes offered
- the reputation of the rendering service
Experienced rendering services will have a large portfolio of previous work to share with you. They will be able to make recommendations about styles, colours and finishes that will flatter your home and explain the rendering process in detail. A cheap quote may be for a skim coat only, while a complete quote will include surface preparation, the number of coats of render needed for a professional finish, detail work and clean-up.
Render can also be sprayed onto a wall.
Hiring a renderer
When it comes time to hiring a renderer, take time to make sure they are right for your job. Some questions to ask then include:
- Are you licensed or qualified?
- Are you insured to work in my home?
- How long will my job take?
- Can you provide a written quote?
- Do you have references I can follow up?
- Can I see examples of your work?

How much does rendering cost?
So how much will your rendering job cost?
The cost of your rendering job will be determined by the type of render utilised, how much detail is required, access to your property and if you require scaffolding.
Renderers charge by the square metre. Depending on your location and the rendering service you choose , their rates, including materials, can vary from $50 per square metre for a single storey home and will be slightly higher for a two storey home.
The average residential home has about 400 square metres of exterior wall area. At $50 per square metre, a home of that size would cost in the region of $20,000.
Another cost to factor into your render project is scaffolding. Hiring the scaffolding yourself could help save you on the final cost, though most renderers will include this in their quote.

From the horse's mouth…
For an idea of what rate the pros work off hipages.com.au caught up with Sydney-based Render My Home
for their input.
“Not everything can be calculated on square meter rates. It depends how much detail there is or you want there to be on your home, which would be an added cost, usually a per hourly cost. Rates have actually declined over the last 15-20 years. Not surprisingly the decline in rates has translated into a significant decline in workmanship quality.”
Currently rates should be anywhere from:
- $60 + GST per square meter for traditional render
- $80 + GST per square meter for a polymer modified render system
“We would steer clear of anyone charging anywhere near $30 per square metre!"
#hiptip The most popular and durable type of render is acrylic
In terms of different types of render, bagging render is the cheapest. This is a very rough version of cement rendering, using only one coarse coating of render mix. The most popular and durable render is acrylic. It gives you a range of options in terms of texture finishes and colour as well as water resistance and flexibility that reduces cracking on your exterior façade. It is typically applied over cement render which makes it much stronger, flexible and able to breath under it.
