Tools Required for DIY Plastering A Ceiling

When plastering a ceiling, having the right tools for the job is essential. DIY plastering may seem daunting, but with the right tools and techniques, it can be a satisfying and successful project. This guide will outline the essential tools required for DIY plastering a ceiling or for any other interior plastering in Auckland project.

Trowel – A trowel is a necessary tool for plastering. It is used for smoothing and levelling the surface of the plaster and for applying it evenly onto the ceiling. There are different types of trowels, so it is important to select one suitable scoop for the correct type of plaster.

Hawk – A hawk is a flat board with a handle that is used to hold the plaster. It is an essential tool for plastering a ceiling, allowing the plasterer to keep the plaster close and within easy reach.

Mixing Bucket – A mixing bucket is required for mixing the plaster. It should be large enough to hold enough plaster and water, allowing easy mixing without spilling.

Jointing Knife – A jointing knife is used to apply a final smooth finish to the plastered surface. A flexible, stainless steel jointing knife works best.

Sandpaper – Sandpaper is used to smooth the surface of the plaster once it has dried. It is essential to use fine-grit sandpaper to avoid damaging the plaster surface.

Applying plaster to a ceiling can be challenging, but with the right tools and techniques, it can be rewarding.

Preparing The Site

Before beginning the house plastering process, it is crucial to prepare the site properly. All furniture and other objects should be removed from the room, and the floor and walls should be covered with plastic sheeting. In addition, any light fittings and electrical outlets should be taped to prevent the plaster from seeping inside, and the room should be well-ventilated. It’s also essential to prepare your tools, including a mixing bucket, a plastering trowel, a hawk, and a sponge.

Prepping The Plastering Surface

Whether it is interior or exterior plastering in Auckland, it is important to properly prep the ceiling. This involves removing debris or loose plaster and cleaning the surface to remove any dirt or dust. If the surface is particularly uneven, a bonding agent can be applied to provide extra adhesion. Once the surface is prepped, apply scrim tape to the edges to prevent cracking and ensure the plaster sticks properly.

Making The Mixture

The key to a successful plastering job is getting the mixture right. Begin by pouring clean water into a mixing bucket, and then gradually add the plaster. Blend the mixture together using a mixing tool or an electric mixer until it is smooth and free of lumps. The ideal consistency is thick and creamy, similar to toothpaste. Always mix the plaster just before applying it, as it will start to set quickly once it comes into contact with water. Once the plaster is mixed, use it to the ceiling, moving swiftly to ensure it does not dry out during the application process.

Applying The Plaster On The Ceiling

For plastering a ceiling, you must mix it according to the manufacturer’s instructions and transfer it to a hawk or plasterer’s pan. You should then apply the plaster using a trowel and ensure it is spread uniformly. Work in small sections at a time, starting from the corner of the ceiling and working towards the centre. Once you have covered the entire ceiling, use the trowel to smooth out any irregularities in the plaster. Working quickly before the plaster dries, which may occur in as little as 20 minutes, is essential.

Creating A Smooth Surface Using Sanding

After the plaster has thoroughly dried, use a sanding block and fine-grit sandpaper to smooth out any bumps or rough patches. Start by sanding lightly, moving in circular motions to avoid creating patterns on the plastered house. Work from one corner of the top to the other, removing excess plaster. Once you have finished sanding, wipe the ceiling down with a clean cloth to remove any residual dust. You can then repeat the process with finer-grit sandpaper. By sanding the plaster, you will create a smooth and even surface, ready for painting or wallpapering.

What Is The Cost Of Plastering A Ceiling

Several factors typically come into play when determining the cost of plastering a ceiling. One of the primary things to consider is the size of the ceiling that needs to be plastered. A large ceiling will require more plaster material, time, and labour, which will cost more.

Another critical factor to keep in mind is the condition of the ceiling. If the roof is in good condition with only minor wear and tear, the plastering process could be relatively quick and straightforward, and the cost could be lower. But if there are significant cracks, holes, or other damage, repair work will be necessary before the plastering can commence, which could increase the overall cost.

Working with a professional plasterer can also impact the cost of the project. Plasterers charge varying rates; some may include additional costs beyond just the plastering itself. It is always advisable to obtain several quotes from different plasterers to determine the average price in your area.

Finally, the type of plaster chosen can also affect the price. Some plaster types come in at a higher cost than others based on their composition and quality. However, it is essential to remember that a higher-quality plaster often gives better results and is likely to last longer, making it a more cost-effective option in the long run.


As you can see, plastering a ceiling (DIY) is no easy feat. It requires skill and precision to ensure the job is finished to a high standard. You may want to practise on scrap pieces of plywood before starting the project to avoid making too many mistakes. Above all else, safety is paramount and protective eyewear, gloves, and a dust mask must be worn at all times when performing this task. With careful planning, patience and suitable materials, you may be able to achieve a successful outcome with your DIY ceiling repair project. If not, do not hesitate to seek assistance from expert tradesmen who can carry out the work professionally and with efficiency in a short time. After all, ensuring your space remains safe and secure should always take precedence over trying out any new home improvement projects yourself.
