So, whether you are a beginner or an experienced plasterer, read on to learn more about this versatile tool!

How to Choose the Best Brick Trowel

When choosing a brick trowel, there are several factors to consider. The size of the trowel is crucial, as it will determine the amount of plaster you can apply at one time. Opt for a trowel that is comfortable to hold and fits your palm. Another consideration is the shape of the trowel. There are a variety of shapes available, such as square, rectangular, and rounded, each offering different advantages. The square-shaped trowel is ideal for creating straight lines, while the rounded shape is more suitable for rounding off corners.

In addition to the shape, the material of the plastering trowel is also important. Most brick trowels are made from steel or aluminium, each having its own benefits. Steel is more durable and can withstand intense use, while aluminium is lightweight and easy to manoeuvre. Ultimately, choose the material that works best for your needs and preferences.

Using a Brick Trowel for Plastering

Now that you have the right tool in hand, let’s explore the step-by-step process on how to use brick trowel for plastering:

Prepare the Surface 

Before applying plaster, ensure that the surface is clean, dry, and free of any debris. Proper surface preparation is essential for achieving a smooth and even finish.

Mix the Plaster 

Prepare the plaster mixture according to the manufacturer’s instructions. Achieving the right consistency is crucial for easy application and a professional finish.

Load the Trowel 

Using our high-quality brick trowel, scoop an appropriate amount of plaster onto the blade. Avoid overloading the trowel to maintain control during application.

Apply the Plaster 

Starting from the bottom of the surface, use the plastering trowel to apply the plaster in smooth, even strokes. Maintain a consistent pressure to ensure an even application.

Smooth and Level 

Once the plaster is applied, use the flat edge of the trowel to smooth and level the surface. Pay attention to any uneven areas and work them until the surface is uniform.

Finish and Clean 

After achieving the desired finish, clean any excess plaster from the trowel and allow the plaster to dry according to the manufacturer’s recommendations.

Common Mistakes When Using a Brick Trowel

When using a brick trowel, it is important to avoid common mistakes that can compromise the finish and effectiveness of the plastering job. Here are three common mistakes to avoid:

Incorrect Angle 

One of the most common mistakes is holding the trowel at an incorrect angle. It is essential to hold the trowel at a 30-degree angle, with the bevel facing up. This angle allows the plaster to be applied evenly and prevents ridges and seams from forming.

Not Applying Enough Pressure 

Applying too much or too little pressure when plastering can also lead to uneven or improper results. It is important to apply firm and even pressure to the trowel, slowly moving it across the surface. Applying too much pressure can result in a bumpy finish, while applying too little pressure can result in thin layers.

Not Rotating the Trowel

 Another important step is to rotate the trowel periodically while plastering. This helps distribute the plaster evenly and prevents the formation of ridges and lines. Rotating the trowel also ensures an even distribution of pressure and prevents your arm from getting tired.

Final Steps for Plastering

After applying the plaster with the brick trowel, there are a few final steps to complete the plastering process.

Applying a Skim Coat 

Once the plaster has dried, it may be necessary to apply a skim coat to create a smooth and uniform surface. A skim coat is a thin coat of plaster applied over the existing plaster to create a smooth finish. It can be applied with a float trowel or a brush.

Finishing the Wall 

Once the skim coat is dry, the wall is ready to be finished. This can be done by applying a final layer of plaster to create a smooth and polished finish. This layer can be applied with a finishing trowel or a sponge float.

By following these steps and using the proper tools and techniques, you can create professional-looking plastering results using a brick trowel. Remember to practise proper technique, choose the right type of trowel, and avoid common mistakes to achieve a smooth and polished finish.
