Plastering is a timeless craft, often seen in the construction and renovation of homes and buildings. It involves applying a smooth finish to walls, ceilings, and other surfaces, which serves both as an aesthetic enhancement and a functional feature. Whether you’re a DIY enthusiast or a professional plasterer, understanding the right tools and techniques can make a significant difference in the outcome of your project.

In this article, we’ll explore the essential tools you need when plastering, discuss the plastering process, and provide some tips for ensuring your plastering job is flawless. By the end, you’ll have a solid understanding of what’s required to achieve a smooth and durable plastered surface.
What Tools Do You Need When Plastering?
Plastering requires several tools to ensure that the job is completed to a high standard. The right tools not only make the job easier but also help you achieve a smooth, even finish. Here’s a breakdown of the essential plastering tools list:
Trowel
- A plastering trowel is one of the most essential tools for any plastering job. It’s used to apply, spread, and smooth the plaster onto the surface. Trowels come in various shapes and sizes, but a standard 12-inch trowel is most commonly used. A well-maintained trowel with a comfortable handle will make it easier to manipulate the plaster.
Hawk
- The hawk is a flat, square platform used to hold the plaster mix before it’s applied with the trowel. This tool is especially helpful when working on large areas, as it allows you to carry a generous amount of plaster in one hand while applying it with the trowel in the other. It provides balance and stability, making it easier to work without interruption.
Plastering Float
- The float is a tool used to smooth out the plaster after it’s been applied to the wall. It helps create a fine finish and removes any ridges left by the trowel. Float tools come in several materials, including rubber, sponge, and plastic, and are ideal for smoothing and finishing the surface once the plaster has dried to a certain point.
Mixing Paddle
- A mixing paddle is essential for combining the plaster with water to achieve the right consistency. This tool is especially important if you are mixing larger batches of plaster, as it ensures an even mix without lumps. A sturdy drill with a paddle attachment is the best tool for this job.
Bucket
- A bucket is a must-have for mixing and storing plaster. Choose a bucket that is large enough to hold the amount of plaster you need and made from durable material to withstand the weight of the mixture. Many plasterers use 20-litre buckets for standard jobs.
Corner Trowel
- For those tricky corners, a corner trowel is a specialized tool designed to apply plaster smoothly to edges and corners. Its angled shape allows it to fit perfectly into corners without making a mess or leaving uneven edges. This tool is especially useful when working with plasterboard or when creating sharp, precise corners.
Plastering Sponge
- A plastering sponge is often used to soften and finish the plaster once it has dried slightly. By gently rubbing the sponge on the surface, you can remove any imperfections and create a smoother finish. It’s a useful tool for achieving that perfect final touch.
Scoring Tool
- Once the plaster has been applied and has begun to set, a scoring tool is used to create grooves or scores in the plaster. This is usually done to improve adhesion when applying additional coats of plaster. It’s also helpful for creating a textured finish, depending on your design needs.
Spirit Level
- A spirit level ensures that the plaster you apply is even and level. While you may not need to use it for every plastering job, it’s particularly useful when you’re applying a base coat of plaster or working on larger surfaces.
Dust Mask and Safety Goggles
- Safety should always be a priority when plastering. The dust produced during plastering can be harmful if inhaled, so wearing a good-quality dust mask is essential. Additionally, goggles protect your eyes from dust, as well as from any splashes of plaster.
With these tools in hand, you’ll be prepared for any plastering task. However, knowing how to use these tools properly is just as important as having them. The next section covers the plastering process and some tips for making the job easier.
The Plastering Process: Step-By-Step
Plastering might seem intimidating at first, but with the right tools and technique, it becomes much easier to handle. Here’s a basic guide to help you get started with plastering:
Step 1: Prepare the Surface
Before you begin plastering, the surface needs to be clean and free of dust or debris. If you’re plastering over a wall with old paint or wallpaper, you should remove these layers to ensure that the plaster adheres properly. If necessary, apply a bonding agent to help the plaster stick.
Step 2: Mix the Plaster
Use a mixing paddle to blend your plaster powder with water in a bucket. Follow the instructions on the plaster packaging to achieve the correct consistency—typically, the mixture should be smooth and creamy but not too runny. The right consistency ensures that the plaster adheres well and spreads evenly.
Step 3: Apply the First Coat
Use your trowel to apply the first coat of plaster. Start by working in small sections, spreading a thin, even layer of plaster over the surface. Hold your trowel at a slight angle to control the thickness and avoid over-applying plaster.
Step 4: Smooth and Level the Plaster
Once the first coat has been applied, use your float to smooth out the surface. The float helps remove any bumps or ridges left by the trowel and creates a consistent texture. Use light, circular motions to ensure the surface is even.
Step 5: Apply Additional Coats
Allow the first coat to dry and harden before applying a second layer. Depending on the surface and the finish you’re aiming for, you may need to apply multiple coats of plaster. After each coat, repeat the smoothing and levelling process.
Step 6: Finish the Surface
Once you’ve achieved the desired thickness, use your plastering sponge to smooth out any remaining imperfections. If you want a polished, glass-like finish, gently rub the surface with a damp sponge to eliminate small bumps and ensure the plaster is flawless.
Common Mistakes To Avoid When Plastering
While plastering can be an enjoyable and rewarding task, there are several common mistakes that beginners often make. Here are a few to avoid:
Not Preparing the Surface Properly
- This is one of the most common mistakes. Failing to prepare the surface—whether by not cleaning it thoroughly or not applying a bonding agent—can result in the plaster not adhering correctly. Always ensure the surface is clean, dry, and ready for plaster.
Using Incorrect Consistency
- The plaster mixture should be smooth and creamy but not too runny. Using a mixture that’s too thick can make it difficult to spread, while a mixture that’s too runny may lead to an uneven finish. Always mix the plaster according to the manufacturer’s instructions.
Skipping Layers
- While it may be tempting to apply a thick first coat, plastering in multiple layers is essential for achieving a professional finish. Applying thin layers of plaster allows for better drying, stronger adhesion, and a smoother finish.
Not Cleaning Your Tools
- Dirty tools can negatively affect your plastering process. Always clean your trowel, float, and other tools regularly to prevent them from accumulating dried plaster or dust. This helps maintain the quality of the finish.
Rushing the Process
- Patience is key when plastering. Rushing through the layers, not allowing sufficient drying time, or not smoothing the surface properly can lead to a subpar finish. Take your time and ensure each step is done correctly.
Conclusion
Plastering can be a challenging but incredibly rewarding task when done correctly. By ensuring that you have the right tools—such as a trowel, hawk, float, and mixing paddle—and following the proper techniques, you can achieve a smooth and professional finish.
Whether you’re tackling a small DIY project or a larger renovation, understanding the plastering process and avoiding common mistakes will set you up for success. Remember, patience and practice are essential, and soon you’ll be able to tackle plastering projects with confidence.
