How to Decorate an Outdoor Brick Retaining Wall

Updated February 21, 2017

An outdoor retaining wall made from brick has a useful purpose, but may also be an eyesore for those who find the material unattractive. Decorating the brick wall gives you the chance to customise the area to your specific tastes and adds personality to what otherwise would appear as a plain surface. Projects to decorate the wall range from the elaborate to the quick and easy.

Clean the surface of the brick to remove any dirt or build-up. Power wash the wall to ensure it's as free of debris as possible. Allow at least 24 hours for the brick to dry. Starting with a clean surface is a necessity regardless of the decorating option you choose.

Paint the brick wall. Use outdoor acrylic paint. Create an entire mural that runs the length of the wall for visual impact. Murals can contain anything from an elaborate scene to a collage of items, designs and words. Paint a simple pattern along the top and bottom of the wall for something more tame. Utilise the wall as a place for creative expression.

Line the top of the wall with heavy, sturdy pieces of outdoor art. Use the wall ledge as a display space for concrete statues or metal sculptures.

Place a row of flower pots along the top ledge of the wall for a natural decoration. Fill them with colourful blooms in the warmer months or stick to evergreen plants for year-round coverage.

Install a mosaic on portions of the outdoor retaining wall. Place a layer of cement on the wall surface and press the tiles directly into the wet cement for the easiest method of creation. You can also press random objects such as old pieces of metal, plastic toys and broken ceramic pieces into the cement to create an abstract work of art.


Check the weather forecast in the days leading up to your planned decorating project. Pick a day where the weather is fairly warm and the skies are clear. If you live in an area with a homeowners' association, check with them before beginning the decorating project as there may be rules in place that limit or forbid what you can do.
