Plastering walls is a common practice in construction and home improvement projects. It helps create a smooth and attractive surface that can be painted or decorated. There are various tools available for plastering, with the corner trowel being one of them. In this article, we will explore whether you can effectively use a corner trowel for plastering walls.
Understanding the Corner Trowel:
Before delving into the applicability of a corner trowel for plastering walls, it is essential to understand what a corner trowel is. A corner trowel is a specialized tool with a flat triangular blade and a handle. It is designed for finishing corners and tight areas, such as internal corners where two walls meet. Unlike a conventional trowel, which has a larger rectangular blade, a corner trowel’s smaller size allows for more precise maneuverability in confined spaces.
Using a Corner Trowel for Plastering Walls:
1. Preparing the Surface:
Plastering walls with a corner trowel requires proper surface preparation. Before starting, ensure the walls are clean, dry, and free from any loose debris or peeling paint. If necessary, use a scraper or sandpaper to remove any imperfections.
2. Applying the Plaster:
To apply the plaster, you can use a hawk and a steel trowel to scoop and spread a thin layer of plaster onto the wall surface. For larger areas, a larger rectangular trowel may be more efficient. However, for corners and tight spaces, a corner trowel can be used effectively.
3. Smoothing Corners:
Once the plaster is applied, you can use a corner trowel to work on the corners. Hold the trowel at a slight angle and apply light pressure, gradually working the trowel along the corner to smooth out any excess plaster. The triangular blade of the corner trowel allows for precise control, making it ideal for achieving clean finishes in corners.
4. Feathering the Edges:
After smoothing the corners, use the corner trowel to feather the edges. This technique involves blending the edges of the plaster with the surrounding wall surface to achieve a seamless finish. The narrow blade of the corner trowel can be maneuvered easily to provide a neat feathering effect along the edges.
5. Finishing Touches:
After using the corner trowel, it is essential to evaluate the plaster’s consistency and overall smoothness. If necessary, further adjustments can be made using the corner trowel or other plastering tools to ensure an even and uniform surface.
While a corner trowel may not be the primary tool for plastering larger wall areas, it can certainly be a valuable asset when working on corners and tight spaces. The triangular blade and maneuverability of a corner trowel allow for precise control and help achieve smooth and professional-looking finishes. Whether you are a DIY enthusiast or a professional plasterer, having a corner trowel in your arsenal can prove beneficial when plastering walls.
