Painting concrete is normally only considered when it's necessary to cover an existing slab, according to the Concrete Network. For example, after a crack has been repaired, employ a concrete colorant or paint to help disguise the imperfection in the pavement. Although painting pavement is primarily done after repairs, you can also use this method to decorate concrete surfaces.
Things You'll Need
- High pressure hose
- Detergent or degreasing solvent (optional)
- Long handled scrub brush (optional)
- Concrete paint
- Roller pan
- Paint roller
- Roller cover
- Paint roller handle extension
- Concrete patch (optional)
Paint Repaired Concrete
Remove dirt or debris from the pavement. Do this by sweeping the surface with a broom and then rinsing with a high pressure hose. If the surface has oil or gasoline spots, as in the case of a garage or driveway surface, scrub the areas with a strong detergent or degreasing solvent, then rinse with a high pressure hose.
Determine the type, color and amount of paint you need. Pour the paint into the roller pan, and using a roller applicator having a handle extension, paint the pavement as needed. There is a special type of concrete paint that allows the pavement to "breathe," so that moisture collected evaporates through the paint layer and not be trapped beneath the surface.
Apply at least two coats and allow each to dry according to the manufacturer's instructions before walking or placing objects, such as furniture or plants, on the surface.
Create a Faux Effect
Clean the pavement surface thoroughly prior to beginning your faux paint job. The How to Faux Finish website suggests vacuuming and wiping with a damp cloth to prepare. (Reference 2)
Fix imperfections by patching cracks and filling holes. Allow the concrete patch ample drying time before applying a gray color base coat to the surface using a roller applicator. Allow the paint to dry thoroughly.
Apply the faux design. For instance, apply a faux brick effect as a top coat over the gray base coat. Create the brick pattern using a sponge applicator that closely approximates the size and shape of a brick. Pour the paint in the tray, lightly dip the face of the sponge in the paint, and very lightly press the sponge onto the pavement. Repeat until the entire surface is covered. Don't have too much paint into the sponge, and don't press too hard when sponging the color onto the surface. Be sure to leave a uniform space around each brick so the base coat shows, giving the appearance of mortar lines. Allow ample drying time before walking on the surface.
Tips & Warnings
- The Concrete Network notes that fresh concrete should never be painted. Allow the pavement to cure for at least 28 days, or per the manufacturer's directions.
