Design ideas for painting concrete include painting the walls white to create a modern-looking room or using stains or dyes to create a patterned floor. Although decorating a concrete floor is referred to as painting, the products used are not technically paints, but rather water-based acrylic stains.
Painting the concrete walls of a room all white gives it a modern appearance, whereas painting it dark gray results in a more industrial design scheme. Concrete walls painted in a singular tone are ideal, as they enhance the space while emphasizing the central objects of the room.
Painting concrete floors requires special dyes or water-based acrylic stains formulated specially for concrete. Painting concrete with regular house paint is not recommended due to the porous nature of concrete, which causes paint to peel. For a concrete floor design that features marbling and color variation, a water-based dye is ideal, as solvent-based ones tend to be uniform in color when finished.
Many colors of water-based acrylic stains are available for decorating concrete floors, such as metallic tints and black and white. A line of acrylic-urethane polymer stains for concrete floors was released by Rembrandt in 2003 that featured colors such as vibrant red, orange and cobalt blue. These stains are especially useful when creating a bold concrete floor design.
