Corner Trowel

A corner trowel is a specialized tool designed for the finishing of drywall and plastered corners. It consists of a flat, rectangular metal plate with a handle attached to one side. The plate is shaped at a 90-degree angle to reach into hard-to-reach corners to smooth out and create an even surface finish.

In drywall installation, a corner trowel is used to apply joint compound to the inside and outside corners where two pieces of drywall meet. The tool is used to create a smooth and even surface along the corner, eliminate the joint lines, and create a seamless finish. This process is essential for a professional and aesthetically pleasing drywall installation.

In plastering, corner trowels are used in the same way, applying plaster compound to the inside and outside corners of the wall. The corner trowel makes it easy to reach the difficult angles and create an even finish along the corner. The tool is also useful for repairing and touching up existing plastered surfaces, enabling users to easily patch and blend corners to match the surrounding area.

The use of a corner trowel provides several benefits. Firstly, it allows for more precise application of joint compound or plaster, resulting in a smoother finish. Additionally, the tool eliminates the need for sanding or heavy texturizing along the surface. This means that using a corner trowel ultimately saves time and effort in finishing drywall or plaster corners. Finally, using a corner trowel creates a more professional appearance, by avoiding visible joint lines and ensuring seamless corner finishes that stand out as a hallmark of quality workmanship.

In conclusion, a corner trowel is an essential tool for anyone involved in the installation and finishing of drywall or plastered corners. Its versatile nature, ease of use, and superior finishing capabilities make the corner trowel a must-have in any drywall or plastering toolkit.
