Maintaining your home is very important to ensure your property lasts for a long time and retain its market value. The original plastering of an old structure adds value to the design. But before we can even consider how much plastering will cost, we have to know what type of plaster we have in your home.
If your house is pre-1919 until the 1950s, there is a strong possibility that you have a Lime plaster. The colour of lime plaster is off-white, which is the typical construction material during that period. A pinkish colour plaster would indicate that it’s a plaster that was bounded with gypsum. The gypsum was used in the 1950s and is still being used today.
A significant disadvantage of using gypsum is that it cannot be used in exterior walls and damped places because it absorbs moisture. But for interiors walls, it easy to apply and sets very quickly. Gypsum drywalls have also replaced traditional plastering for interior walls and ceilings. A more conventional cement mortar plaster is used for exterior walls, a mixture of cement and sand. On the other hand, an earthy colour would suggest that an earth binder was used in the plaster.
In other words, the cost of plastering will depend on what type of plaster you have and the area you need to repair. Hiring a contractor that has experience with traditional finishes will be much more expensive than a regular finish.
The cost of plastering would also depend on the type of plastering you are going to have. Replastering or skimming means adding a new thin coat of plaster on top of an existing application. Replastering is done to smoothen the surface in preparation for the fresh paint or wallpaper and is cheaper to do.
On the other hand, full plastering involves removing the old plaster, creating a new base and skimming the surface, and then doing finishing. Because of the amount of time and material needed for full plastering, it is more expensive.
Skimming a medium-sized room would cost around AUD 700.00 and other materials. Full plastering, on the other hand, will cost AUD 1200.00 and other materials. Prices may vary depending on the area. Plastering traditional materials like Lime would cost more due to more expensive materials and specialized contractors applying the plaster.
Plastering is very important and requires professional skills. So it’s much better if you let the experts do it for you. They have more skills and experience that are necessary to have a perfect finish. Rendering also needs specialized equipment that will not be readily available for a DIY project. Plastering leaves little room for error; a low quality DIY plaster will cause you more money since it has to be fixed again by professional contractors.
Plastering using a professional contractor is worth it since you are assured of the quality. You can also ask them to fix whatever problems come out since a warranty usually covers the work in the contract. It is essential to do a bit of research and background check before hiring a contractor.
