The cost varies by state and is determined by the size of the project, its complexity, the type of plaster used, and the number of coats necessary.

Plasterers typically charge a set amount for a room or a whole house. This service includes the main plastering process, as well as the option of having the area and constriction waste cleaned following the service, for an extra charge. Plastering a three-bedroom house, for example, will cost between $10,000 and $15,000 approx. for a regular project, including materials and installation. You will, however, be charged an hourly rate if you are planning a little remodelling or mending a damaged wall.

  • The ease of access to the job that needs to be done is another important thing that needs to be considered. Plaster ceiling repair has higher pricing than plaster wall repair because the walls are more accessible than the ceiling.

What is the best plaster for you?

Different types of plastering vary in appearance, installation, and durability. Knowing the type of plaster will help you communicate to the plasterer the kind of service you need, and you will have a clear and realistic expectation from the plastering job that was needed for you.

  1. Plasterboard

Plasterboard, often known as drywall or Gyprock, is the most popular choice among Australian builders since it's simple to install and great for lining walls and constructing partitions. It also comes in sound insulation, moisture resistance, and fire resistance varieties.

  1. Wet Plaster

Wet plaster is a solid mixture of lime, cement, gypsum, or other elements that create a smooth and long-lasting wall surface. Depending on the undercoat, wet plastering requires a skilled application and a drying time of 2 to 7 days. Wet plaster is more soundproof and fire-resistant than drywall.

  1. Ornamental plaster

Ornamental plaster is a type of plaster used to sculpt design features such as mouldings and cornices. It can be painted on the walls, columns, or ceilings directly.

  1. Lime plaster

Lime plaster isn't used very often because it necessitates a specific application process. It's made of lime and sand, and it's breathable and long-lasting.

  1. Cement plaster

Cement plaster is a rough, grey-coloured plaster made of cement and sand. It produces a robust and long-lasting wall finish, but it is prone to shrinking and cracking over time.

Gypsum plaster is simple to work with and gives a smooth, paint-ready surface. It does not shrink and is extremely mould and mildew resistant.

How can you save money when you hire a Plasterer?

Hiring a plasterer does not need to be stressfully expensive. Here are some ways you can consider saving even if you have a plasterer to do the job for you.

  1. Clear the spaces 

Make it easier for the plasterers by clearing out the rooms and covering whatever you can't take out. This way they don’t have to spend clearing the roof.

  1. Remove any existing plaster, plasterboard, skirting boards, or wallpaper 

Removing the old materials will almost certainly cost you a lot of money. Do it yourself if you're not scared to get your hands dirty and remove whatever you can.

  1. Add a layer of plaster primer

If the wall has been stripped bare, apply a coat of plaster primer so the specialist can apply the wet plaster immediately. If you don’t have experience doing this, we suggest you avoid it and wait for a professional to arrive.
