If you have ever observed an experienced plasterer at work, you may have noticed a peculiar tool they use to spread and smooth plaster on walls and ceilings. This tool, which is essential to the job, is called a plasterer’s trowel.
A plasterer’s trowel, also known as a finishing trowel or a float, is a handheld tool that has a flat steel blade with a curved end. The blade is usually about 4 to 5 inches wide and is attached to a handle. The handle is typically made of wood or plastic and is curved for the plasterer’s comfort and control.
The plasterer’s trowel is specifically designed for applying and finishing plaster or other similar materials, such as stucco or mortar. It is used to spread the plaster evenly and smoothly across surfaces, ensuring a professional and polished finish. The curved end of the trowel allows the plasterer to create smooth, rounded edges and corners.
Using a plasterer’s trowel requires skill and precision, as the plasterer must apply the right amount of pressure to achieve the desired smoothness and texture. It takes practice to master the techniques of using the trowel effectively, such as the angle at which it is held and the motion used to spread the plaster. A skilled plasterer can create a flawless surface that is ready for painting or further finishing.
Spatula or Trowel
When it comes to plastering, the tool that professionals use to apply and smooth plaster is commonly known as a plasterer’s trowel. However, in some regions or industries, it may also be referred to as a spatula. While both terms are used interchangeably, there are some subtle differences in their design and usage.
Plasterer’s Trowel
A plasterer’s trowel is a specialized tool with a flat, rectangular blade made of stainless steel or carbon steel. It has a comfortable handle attached to one end of the blade, allowing for better control and maneuverability. The blade is usually flexible, which makes it easier to apply and spread plaster, creating a smooth and even finish.
Plasterer’s trowels come in different sizes, ranging from small hand trowels for detailed work to larger trowels for covering larger surfaces. The size of the trowel typically depends on the specific task at hand and the personal preference of the plasterer.
These trowels are designed to be lightweight yet sturdy, ensuring that plaster is applied efficiently without putting excessive strain on the user’s hand and wrist. The flat blade of the trowel allows for easy control, making it an essential tool for plastering professionals.
Spatula
A spatula, on the other hand, is a broader term that encompasses a wider range of tools with flat blades. While it can refer to a plasterer’s trowel, spatula is a more generic term used in various industries and contexts.
In the culinary world, a spatula refers to a kitchen tool with a flat, narrow, and flexible blade, usually made of stainless steel or silicone. It is used for flipping and turning food during cooking, scraping the sides of mixing bowls, and spreading icing or frosting on cakes. These spatulas are not suitable for plastering due to their smaller size and lack of rigidity.
In the medical field, a spatula is a specialized tool used for various purposes, such as spreading ointments, removing samples for testing, or manipulating small objects during surgical procedures. These spatulas are typically made of stainless steel and have a narrow, flat blade.
While the term spatula is more encompassing, plasterers in some regions may use it interchangeably with plasterer’s trowel. However, it is essential to note that a plasterer’s trowel is specifically designed for plastering tasks, while a spatula may serve different purposes in different industries.
Types of trowels
Plastering trowels come in various types, each designed for specific tasks and applications. Here are the most common types of trowels used by plasterers:
| Trowel Type | Description |
|---|---|
| Finishing trowel | A finishing trowel is used to achieve a smooth, flat finish on the plaster surface. It is typically rectangular or square in shape, and has a straight edge. |
| Gauging trowel | A gauging trowel is a small, rectangular trowel used for mixing and applying small amounts of plaster or other materials. |
| Corner trowel | A corner trowel, as the name suggests, is used for plastering corners. It has a triangular shape with one rounded edge and one pointed edge, allowing for easy plastering in tight spaces. |
| Edging trowel | An edging trowel is used for creating smooth, rounded edges on plaster surfaces. It is typically smaller and narrower than a finishing trowel. |
| Notched trowel | A notched trowel has a serrated edge or notches on one or both sides. It is used for applying adhesive or mortar, and for creating ridges or grooves that help with the installation of tiles or other materials. |
| Pool trowel | A pool trowel is a small, rectangular trowel with curved edges. It is specifically designed for finishing and smoothing plaster on curved surfaces, such as pools or rounded corners. |
These are some of the most common types of trowels used by plasterers. The choice of trowel depends on the specific task and the desired finish. A skilled plasterer will have a selection of trowels in their toolkit to ensure they have the right tool for the job.
How to choose the right trowel
Choosing the right plasterer’s trowel is essential for achieving professional and smooth finishes on plastering projects. Here are some factors to consider when selecting the right trowel:
1. Size and shape
The size and shape of the trowel can greatly affect the efficiency and control during plastering. Smaller trowels, such as 10 to 12 inches, are ideal for detailed work and finishing touches. On the other hand, larger trowels, such as 14 to 16 inches, are better suited for covering larger areas quickly. The shape of the trowel can also vary, with some featuring a pointed tip for precise work, while others have a rounded tip for spreading plaster evenly.
2. Blade material
The material of the trowel blade can significantly impact its performance and durability. Stainless steel blades are a popular choice due to their resistance to rust and easy clean-up. Carbon steel blades, on the other hand, are known for their flexibility and ability to hold more plaster. However, they require regular cleaning and maintenance to prevent rusting. Consider the type of work you will be doing and choose a blade material that suits your needs.
3. Handle
The handle of a trowel plays a crucial role in providing comfort and control during plastering. Look for a handle that is ergonomically designed, providing a comfortable grip and reducing hand fatigue. Rubber or soft grip handles are usually preferred, as they offer better control and reduce the risk of slippage. Some trowels also feature a finger guard to protect your hand from accidental injuries.
It is also important to consider the weight of the trowel, as a heavier trowel can lead to fatigue and strain during extended use. Test the weight and grip of the trowel before purchasing to ensure it feels comfortable in your hand.
Remember to take into account your personal preferences and the specific requirements of your plastering project when selecting a trowel. By choosing the right trowel, you can achieve smoother and more professional finishes in your plastering work.
Tips for using a plasterer’s trowel
When it comes to using a plasterer’s trowel, there are a few important tips to keep in mind. Whether you are a beginner or have some experience, these tips can help you achieve a smooth and professional finish.
1. Choose the right trowel
One of the most important factors in achieving a smooth finish is using the right trowel for the job. There are different types and sizes of trowels available, so it’s essential to choose the one that suits your project. A wider trowel is generally used for larger areas, while a smaller one is ideal for detail work.
2. Prepare the surface
Before using the trowel, it’s crucial to properly prepare the surface you will be working on. Make sure the surface is clean, dry, and free from any dust or debris. If necessary, apply a primer or basecoat to ensure a better bond between the plaster and the surface.
3. Apply the plaster
When applying the plaster with the trowel, start from the bottom and work your way up. Use a firm and even pressure to spread the plaster smoothly and evenly. Avoid applying too much pressure, as this can create unevenness or push out excess plaster.
4. Maintain a consistent angle
Throughout the plastering process, it’s crucial to maintain a consistent angle with the trowel. This will help you achieve an even coat and avoid any lumps or bumps. Keep the trowel at a slight angle, around 30 degrees, and use a smooth and steady motion.
5. Feather the edges
When you reach the edges of the area you are plastering, it’s important to feather them out to create a seamless finish. Use a light touch and blend the plaster into the surrounding surface. This will help to avoid any visible lines or ridges.
Following these tips can help you achieve a professional and flawless finish with your plasterer’s trowel. Practice and patience are key, so don’t be discouraged if it takes a bit of time to master the technique. With time and experience, you’ll be able to create smooth and beautiful plastered surfaces.
