If the walls in your house are bare and there are no paintings or pictures to make them look appealing, you can use wall molding. It's appropriate height is along the hip area of the walls, which is higher than the chair rail and goes all the way to the floor. When installing, you need to remember the points below.
To Check the Quality of the Surface
If the walls need repairs to fill out cracks or holes, do so and paint them before installing the wall molding. Failure to do that means the surface will not be even and the installation will not last a long time because moisture and other effects will penetrate and destroy the walls.
Find the Firm Spots
If you fix the wall molding on weak parts of the walls, they will produce a squeaky sound and may soon fall off especially at the corners. Find the studs and fasten the screws such that they go through to the studs. In addition, do not fix it on wet walls. If the molding is fresh or the repair work is still drying up, the walls may retain moisture that will lead to rising dampness. Ensure that they dry adequately before installing the wall molding.
The design should work with the rest of the interior. If you want to beautify your room, look for a design that matches the designs on the doors.
