How to Paint Rounded Corners

Many homes have walls with rounded corners instead of 90-degree angles where the walls meet. This feature, which is known as "bullnose corners" creates a contemporary stylish look, but a slight challenge for painting. If you are painting two separate walls with two different colors, eventually, the colors will have to join in the corner. The challenge is exactly where to join the colors. Paint rounded corners using a few inexpensive supplies that can be obtained at your local hardware or home improvement store.

Rounded wall edges can be painted using two separate colors.
  1. Choose the two paint colors that you would like to use for the adjoining walls. You can choose two similar colors or two completely different colors, depending on your decorating preference. Obtain your paint and other painting supplies at your local hardware store.

  2. Apply the sticky side of the painter's masking tape on one of the edges of the rounded corner, starting at the ceiling and follow it down the length of the wall in a straight line. The edge of the corner can be found where the round area becomes straight. Creating a line with tape in the middle of the rounded corner may not yield good results due to the difficulty in getting a straight line on a rounded corner.

  3. Press the tape down on to the wall carefully and rub it with your hand from top to bottom to ensure that it sticks to the entire length of the wall evenly. This will help reduce the risk of paint seeping under the tape when you begin to paint.

  4. Paint the wall with your darkest color first, using the darker color to wrap around the corner. Apply a second coat of paint if additional coverage is necessary.

  5. Allow the paint to dry thoroughly, according to the paint manufacturer's instructions. Letting the paint dry overnight is a good idea to ensure that it is completely dry prior to removing the painter's masking tape.

  6. Remove the painter's masking tape from the wall carefully. Once the tape is removed, you should see a straight line of your dominant color at the edge of the curve.

  7. Paint the second wall with your other color, applying two coats of paint if necessary. You will need to paint the area where the two colors meet by hand with a paintbrush to ensure straight and even coverage.
