Before diving into the practical steps, let’s briefly discuss what a corner trowel is. A corner trowel is a specialized tool with a triangular shape that’s designed for finishing inside corners. Typically made of steel or plastic, the trowel helps to spread joint compound evenly over corner seams, giving a clean and polished finish.
Before you start, make sure you have everything you need:
Start by mixing your joint compound to a smooth, workable consistency. If you’re using pre-mixed compound, give it a good stir to ensure it’s well-blended. Avoid clumps, as a smooth mix will provide the best results.
Using a drywall knife, apply a liberal amount of joint compound to the corner joint. Make sure to cover the seam where the two adjoining pieces of drywall meet. Don’t worry about making it perfect; the goal here is to get enough compound on the wall to work with.
Now comes the step that will teach you how to use a corner trowel effectively:
Position the Trowel: Hold the corner trowel at a 45-degree angle to the corner. This angle helps the tool fit snugly against the wall and ceiling.
Smooth the Compound: Start at the top of the corner and press the leading edge of the trowel firmly into the joint compound. Drag the tool downwards in a smooth, steady motion. Apply enough pressure to spread the compound but not so much that it removes all of it.
Inspect Your Work: Once you’ve pulled the trowel down to the bottom, lift it away and check for any uneven areas. If you see spots that need more compound, use your drywall knife to add a bit more, and then use the corner trowel again to smooth it out.
After you’ve achieved a smooth finish, allow the joint compound to dry completely. This usually takes a few hours, depending on the humidity and temperature.
Once dry, take your sandpaper and lightly sand the area to create an even surface. Be gentle, as you want to avoid scuffing the corners. Clean up the dust with a damp cloth and prepare for a final coat of paint or primer.
Practice Makes Perfect: If you’re new to using a corner trowel, practice on scrap pieces of drywall. This way, you’ll get comfortable with the technique before moving on to actual walls.
Use Quality Tools: Invest in a good quality corner trowel. A well-made trowel will make all the difference in achieving a smooth finish.
Keep Your Trowel Clean: After each use, clean your corner trowel to prevent the joint compound from hardening on it, which can affect its performance next time.
Watch Tutorials: Sometimes, seeing the technique can be more beneficial than reading about it. Look for video tutorials online to reinforce your understanding.
Learning how to use a corner trowel can seem daunting at first, but with a bit of practice and patience, you’ll be able to create beautifully finished corners that elevate the look of your drywall projects.
