Understanding Your Corner Trowel

Before you dive into drywall finishing, it's important to familiarize yourself with the different types of corner trowels available. The two primary types are the inside corner trowel and the outside corner trowel. An inside corner trowel features a concave blade that perfectly fits into the 90-degree angle of wall corners, allowing you to apply compound smoothly. An outside corner trowel, on the other hand, is flat and straight, ideal for creating clean edges on the outer corners of drywall. Knowing which one to use in various situations will greatly improve your finishing skills.

Preparation is Key

Before using your corner trowel for drywall, ensure that the surface is adequately prepared. This means applying a thin layer of joint compound to the corners with a larger blade first. Once this layer has partially dried, use your corner trowel to smooth it out. Starting with a proper base will make it easier to achieve the desired finish, reducing the time you spend sanding and fixing any imperfections later on.

Technique for Application

When holding the corner trowel, maintain a comfortable grip and adjust the angle based on the corner type you are working on. For inside corners, tilt the trowel slightly and push it into the compound while pulling it away from the corner, applying even pressure. For outside corners, apply compound, and then glide the trowel along the edge with a steady hand. Practice this technique to enhance your control and accuracy, ensuring that compound is evenly spread and smooth.

Timing Matters

Timing your application is crucial for achieving the best results with a corner trowel for drywall. Your joint compound should be partially dry but still damp when you smooth it with the trowel. If you wait too long, the compound will harden and become more challenging to work with, leading to a rough finish. Conversely, if the compound is too wet, it can pull away and create uneven spots. Understanding when to work with the material is vital for a successful finish.

Finishing Touches

Once the initial layers are applied and smoothed with your corner trowel, inspect your work for any imperfections. Use a sanding block to lightly sand any rough spots after the compound has fully dried. Adding a second and even a third layer can be beneficial for achieving a professional-looking finish. Applying these additional layers will give you more depth and a smoother appearance once you complete the sanding process.

Seek Professional Guidance

If you’re uncertain about your finishing techniques or just want to improve your skills further, consider reaching out to a professional. Many experts are willing to share tips and best practices that can help you master the use of the corner trowel for drywall.
