For anyone involved in concrete work or plastering, having the right tools is crucial for achieving a professional and durable finish. Among the array of trowels available, two often get confused: the pool trowel and the finishing trowel. While both are used to smooth and refine surfaces, they are designed with distinct purposes in mind, leading to significant differences in their construction and application. Understanding these differences is essential for selecting the appropriate tool and achieving the desired results.
The most immediately noticeable difference lies in the shape of their blades. A finishing trowel typically boasts a rectangular blade with sharp, square corners. This design allows for precise work along edges, corners, and around obstacles. It’s the workhorse for general concrete and plaster finishing, used to create a smooth, even surface on floors, walls, and various other applications. The sharp corners are invaluable for ensuring clean lines and tight fits in confined areas.
In contrast, a pool trowel features a blade with rounded corners. This seemingly small difference is the defining characteristic of a pool trowel and directly relates to its intended purpose: creating the smooth, curved surfaces found in swimming pools, spas, and other contoured concrete structures. The rounded corners prevent the trowel from digging into the wet plaster or concrete, which is crucial when working on curved walls and bottoms where sharp corners would create gouges and imperfections.
Beyond the shape, the flexibility of the blade often differs between the two trowels. Finishing trowels are available in various levels of flexibility, allowing users to choose one that suits their preference and the consistency of the material they are working with. Some prefer stiffer blades for initial flattening, while others opt for more flexible blades to achieve a final, polished look.
Pool trowels, however, generally tend to have more flexibility than their finishing counterparts. This added flex allows the trowel to conform more easily to the curved surfaces of pools without leaving flat spots or uneven areas. The flexibility helps the user manipulate the wet plaster or concrete smoothly over the contours, ensuring a consistent and aesthetically pleasing finish.
The blade material can also vary, although both are typically made from high-quality steel. However, pool trowels often utilize stainless steel or a similar corrosion-resistant material. This is essential due to the trowel’s constant exposure to water and pool chemicals. Using a standard carbon steel trowel in this environment would lead to rapid rusting and degradation of the tool. While stainless steel finishing trowels are also available, they are not as strictly necessary for general concrete work.
Another subtle difference can lie in the size of the blade. While both types of trowels come in various sizes, pool trowels may sometimes be slightly longer to facilitate working on larger curved surfaces with fewer strokes. However, this is not a universal distinction, and both types are available in a range of lengths to suit different applications and user preferences.
In summary, the key differences between a pool trowel and a finishing trowel can be broken down as follows:
-
Blade Corners: Pool trowels have rounded corners while finishing trowels have sharp, square corners.
-
Primary Application: Pool trowels are specifically designed for curved surfaces like swimming pools and spas, while finishing trowels are for general concrete and plaster finishing on flat surfaces and corners.
-
Blade Flexibility: Pool trowels generally have more flexibility to conform to curves, while finishing trowels come in varying degrees of flexibility.
-
Blade Material: Pool trowels are often made of corrosion-resistant materials like stainless steel due to water and chemical exposure.
-
Size: While both come in various sizes, pool trowels may sometimes be slightly longer.
Choosing the right trowel is crucial for achieving the desired finish and minimizing frustration. Using a finishing trowel with sharp corners on a pool will likely result in gouges and an uneven surface, requiring significant rework. Conversely, trying to achieve sharp, crisp edges with a rounded pool trowel will be nearly impossible.
Therefore, when embarking on a concrete or plaster project, carefully consider the type of surface you’ll be working on. If you’re building or renovating a pool, spa, or any other curved concrete structure, a pool trowel is an indispensable tool. For general flat surfaces and corners, a finishing trowel is the appropriate choice. Understanding these fundamental differences will ensure you have the right tool for the job, leading to a smoother, more professional, and ultimately more satisfying result.
