Installing rounded drywall corners will not be difficult for you. The ease of use that they offer and the professional look make them popular among contractors. In fact, even you need to install rounded drywall corners for your home or office project, and the following steps will make it extremely easy for you:

  • Begin with the preliminary work of cutting out the excess drywall. Draw a template on a piece of plywood or cardboard and then trace it to get an accurate size. You can also use a utility knife from a distance and make appropriate cuts using the tip end. This will ensure that all your corners are perfect, making it easier for you to install rounded drywall corners
  • Now, take two pieces of drywall (equal in width) and arrange them so that they overlap by ½ inch where the corner will be located. Use construction grade tape for binding them together tightly
  • After which, attach another layer by placing it over the first one such that its ends match perfectly with those of the next piece and then finally attach the last one and again tape them tightly together.
  • With this process, you will have completed the rough work of installing rounded drywall corners. Now, it is time to make it symmetrical. Adjust each layer so that they match well with each other at the ends. You must maintain uniform thickness for all layers since this will ensure good results at a later stage.
  • Use a ¼ inch trowel-like tool/metal spatula and shape the corner once again by sanding off the excess paper from around the entire perimeter. This process should also be repeated for all four sides of the corner
  • When everything seems perfect, apply two coats of joint compound on top of each surface using either a 6 or 8-inch taping knife or a putty knife. Make sure that the compound is of the right consistency and if you feel the need to add more water, do it in small quantities to avoid making it too thin
  • Let the first coat dry out completely before sanding it off using medium-grit sandpaper
  • Apply another layer of joint compound over each surface and then let sit again for approximately 15 minutes
  • Finally, smooth everything with a wet sponge or cloth as per your requirement so that you can get rid of all imperfections hence obtaining professional results for installing rounded drywall corners
  • After doing this job perfectly, you will notice that there won’t be any uneven spots remaining on the corners that might spoil their look. It can easily be kept clean and smooth by wiping it with a damp cloth or sponge.
  • After everything has been smoothened out, put on the finishing coat by applying a layer of paint over each surface using a 3-inch brush or roller, and then make sure to let it dry completely before evaluating your work for installing rounded drywall corners.

Precautions while Learning How to Install Rounded Drywall Corners

  • You have to make sure that you cut the drywall using a score and snap method to be easily covered with compound and avoid cracking.
  • If there is any problem with cracking then, you must use screws or nails to secure the corners rather than screwing in from the backside, which is otherwise very common if not careful enough.
  • You must wear gloves while doing this because your hands should be protected from nails that might fall over during the process of cutting drywall.  Incomplete finishing work can also harm your health, like breathing in asbestos fiber from older materials may cause lung cancer, etc.
Wear gloves
