Concrete is usually a dull and drab surface with little visual appeal. Adding color to this material dresses it up and makes it more attractive. While paint is an easy way to add interest to concrete, you're not limited to it. Whether you want to add interest to concrete walls or a concrete driveway, there are ways that you can mark the material without paint.
Mark the concrete with chalk. Use different colors of chalk to draw images on the concrete. This method of marking concrete is easily removed with water, making it a non-permanent way to add temporary color to your concrete surfaces.
Color the concrete with markers. Use different colors to make marks or draw images on the concrete. This method of marking concrete is more permanent than chalk but can be removed with a power washer if necessary.
Mark the concrete with a mixture of food coloring and water. Fill a bowl with equal parts food coloring and water, and apply it to the concrete with a paintbrush, stamps or sponges. For more vivid color, use more food coloring and less water.
Stain the concrete. Purchase a concrete acid stain from a home improvement store. Apply the stain to the surface of the concrete with a handheld paintbrush. Pour a mixture of equal parts water and baking soda, and then pour it over the stained concrete. Wipe up the mixture with a mop or sponge, and rinse it with water.
