Some ways to cover old and ugly brick include painting over it, distressing it to create a unique and rustic look, tiling over the brick and planting ivy or other climbing vines to disguise the brick. Painting and tiling are good indoor solutions, while ivy is a good outdoor solution.
Distressing works both indoors and outdoors.
Paint brick to match the wall colors in the house or blend with the existing decor. Alternatively, paint a mural on the brick area to create a whimsical look. For fireplaces made of brick, arrange tile pieces so that they form a mosaic. Ensure that you properly clean the brick area before attempting to apply paint or tile.
