How to Separate Two Rooms Sharing the Same Wall with Paint

Updated April 17, 2017

Two rooms, one shared wall, and the desire to separate them is an invitation to release your creativity using paint. The answer can be simply painting each section a different colour. Some adventurous solutions involve painting murals or replicas of the galaxy. Other projects include the use of both matt and glossy sheen paints. Paint is one of the least expensive ways to create two rooms that share one wall.

Section off the wall by applying painter's tape vertically between the two rooms. Paint one a solid colour. Let the paint dry completely. Create a formal look in the other room by applying painter's tape horizontally one-third down from the ceiling. Paint a darker colour above the tape and a lighter colour of the same hue below it. Let it dry. This effect works well for a formal living with a more informal dining area

Separate the rooms with vertical strips of painters tape and paint one side with chalkboard paint. Available in dark grey, it is possible to mix chalkboard paint with a white colourant or another colour. This will allow for different colours to be used in stripes or other patterns. This effect works well for a basement where a children's area shares the wall with a home gym or office.

Create a subtle transition between the two rooms. Paint one side several shades lighter or darker than the other. This effect works for an open kitchen and dining area.

Paint the baseboard and crown moulding of one room one colour and the other an alternate colour. Using this option, the actual wall colour can be the same for both rooms.

Paint a mural, the Milky Way or cartoon characters on one side. Stencils can be purchased online or in a paint store. You can create original stencils by drawing on poster board and cutting out the design with a utility knife. This effect works well in a bedroom shared by two children of different sexes, ages and interests.

Paint the room with two differing sets of stripes. On one side, let the top of the diagonal begin at the top left corner and the other from the top right corner. Let them meet where the wall divides the room. For added pizazz, paint each set of stripes alternatively with matt (flat) and high sheen glossy paint. This will result in a shimmering effect.


The psychology of colour is a factor to consider before painting.
