The importance of plastering trowel wear and sharpening

The impact of wear on the performance of plastering trowels
The blades of plastering trowels are usually made of high-quality steel with high hardness and wear resistance. However, in the long-term contact and friction with materials such as putty and plaster, a wear layer will gradually form on the surface of the blade, causing the blade edge to become blunt. It is difficult for a blunt blade to form a uniform putty layer during the plastering process, and it is easy to have uneven wall surfaces. In addition, a blunt blade may also leave scratches on the wall, affecting the beauty and overall quality of the wall.

Wear not only affects the construction effect of the plastering trowel, but also reduces the construction efficiency. A blunt blade requires more force to push the putty material, which increases the physical exertion of the construction workers. At the same time, since the blade edge is no longer sharp, the construction workers need to spend more time and energy to ensure the flatness and smoothness of the wall, thereby extending the construction period.

The importance and necessity of sharpening
Given the impact of wear on the performance of plastering trowels, it is particularly important to sharpen the blade in time. Sharpening can restore the sharpness of the blade and improve construction efficiency and quality. By grinding the edge of the blade, the wear layer can be removed and the blade can be sharpened again. The sharp blade can easily push the putty material to form a uniform putty layer, ensuring the flatness and smoothness of the wall.

In addition, sharpening can also extend the service life of the plastering trowel. By sharpening the blade regularly, the wear rate of the blade can be reduced and its service life can be extended. This can not only reduce construction costs, but also reduce the inconvenience caused by frequent blade replacement.

Methods and precautions for sharpening
Sharpening usually requires the use of professional sharpening tools, such as whetstones, sharpeners, etc. When sharpening, the following points should be noted:

Choose the right sharpening tool: Choose the right sharpening tool according to the material and wear degree of the blade. For blades with higher hardness, a whetstone or sharpener with finer grain size should be selected to avoid excessive wear of the blade.
Maintain the correct sharpening angle: A certain angle should be maintained when sharpening, usually at a certain angle with the edge of the blade. The correct sharpening angle ensures that the sharpened blade is sharp and durable.
Even grinding: During the sharpening process, pressure should be applied evenly on the blade and sharpened along the edge of the blade. Avoid local over-grinding that may cause the blade to become thinner or deformed.
Regular sharpening: In order to ensure the performance and life of the plastering trowel, it is recommended to sharpen the blade regularly. The specific sharpening cycle can be determined according to the construction frequency and blade wear.
