How to Cover an Unsightly Outdoor Wall

Updated February 21, 2017

An unsightly outdoor wall provides an opportunity to create a custom design for your landscape. One way to cover an unsightly wall is to paint a mural that coordinates with your outdoor decor Painting a mural is not complicated, but it can be time-consuming, depending on the intricacies of the design. Select a subject for your mural that you enjoy, such as a waterfall or a garden meadow. Look for design patterns in magazines and online galleries or re-create a design from your favourite vacation photos.

Clean the outdoor wall with appropriate cleaner; concrete cleaner and exterior wood cleaners are available at home improvement stores. Allow the surface of the wall to dry.

Seal a concrete wall with concrete sealer and a wood wall with wood sealer. Allow the sealer to dry.

Paint the wall a background colour that suits your mural design using exterior latex paint. For example, if you are painting a waterfall mural, a white, blue or green background works. If you are painting a forest or garden meadow, different shades of green will provide a suitable background. You will be painting the mural designs on top of the background colour. Omit this step if your mural design is intricate, with many different colours. Allow the paint to dry.

Project the mural design onto the outdoor wall. Trace the outlines of the images using a pencil or a marker. Work in sections from left to right so that you can easily match up the design pattern as needed. Remove the projector.

Fill in the space between the outlines with the appropriate colours of acrylic paint. Keep a copy of the coloured design template nearby for reference. You can work from left to right, or paint the sections by colour. If more than one person is painting the mural, begin on opposite sides of the wall and work toward the centre. Allow the paint to dry.

Seal the finished mural with polyurethane sealer. Allow the sealer to dry.


Cover the unsightly wall with slate tiles, copper ceiling tiles or ceramic mosaic tiles to create a different kind of art piece. Attach the tiles to the wall with thinset or waterproof construction adhesive.
