Mudding corner bead involves a series of simple but crucial steps to ensure a smooth finish. Here's the process broken down into easy steps.
Premixed drywall mud typically will come out of the box a little thicker than you’d want. Mix in a little bit of water and stir thoroughly (ideally using a mixing paddle attachment for your drill). If you’re only making a few quick fixes, you may want to consider using the more quickly setting powdered joint compound, which is mixed using one part water for every two parts powdered mud.
Start by thoroughly cleaning the wall corner. Remove any debris or unevenness. Install the Drywall Corner Bead along the corner and make sure it is level and secure.
Using your drywall knife, apply a layer of joint compound along both sides of the corner bead. Start at the seam between the bead and the wall and apply from top to bottom, applying even pressure. The compound should be thin and even.
Press the drywall tape into the compound, aligning it with the center of the bead. Ensure it's firmly embedded in the compound.
Let the initial layer dry before applying another thin layer of compound using your drywall knife. Repeat this process several times until the wall corner is smooth and seamless. Be sure to feather the edges of the mud toward the wall to create a smooth transition. If applying multiple layers of mud is too much of a hassle for you, then keep in mind that some bead products, like Trim-Tex Fast Edge Paper, require less mud than others.
After the final layer has dried, sand the drywall compound lightly to remove any edges or ridges. Wipe off the excess dust and apply primer and paint to finish.
Mudding bead is a precise job, but ultimately a satisfying one. Here are some important tips to achieve smoother wall corners.
There are many varieties of drywall compound to choose from. All-purpose joint compound is a versatile option but lightweight joint compound is easier to sand, so is often recommended for corner bead. Another type is taping compound, specifically used for embedding drywall tape. Experimenting with each type will help you understand which works best for you.
Applying the correct amount of drywall mud is tricky. Start with a thin layer. Use your knife to apply the mud to the bead evenly. Once it dries, smooth it out using a 10-inch knife. Thin layers help prevent excess joint compound and reduce the chance of cracks forming.
For the best finish, use a taping knife. Hold the knife at an angle and smoothly run it down the drywall corner bead to level the mud. Carefully eliminate any lumps or ridges for a smooth finish.
