Concrete surfaces, both inside and outside the home, can take on a dull gray appearance over time, causing the area around it to look dark and dreary. To combat this common problem, concrete surfaces should be frequently cleaned and painted. Whether the surface you’re looking to paint is a concrete wall, a concrete fireplace, or concrete flooring, you can use the tips we’ve provided below.
Before you begin painting over concrete, the surface needs to be thoroughly cleaned and prepped. This may seem like a time consuming task, but it is necessary if you want the paint to adhere properly and last for an extended period of time.
Materials needed to clean and prep concrete:
– TSP Cleaner- Concrete patch
– Bleach and water solution
– Wire brush
– Power washer (if working with outdoor brick)
How to clean and prep the surface before painting over concrete:
Outdoor concrete –
STEP 1 – Use a power washer to thoroughly rinse off the concrete.
STEP 2 – Use a wire brush to remove any loose material.
STEP 3 – Patch any cracks or holes in the surface with concrete patch. Allow to dry according to package directions.
STEP 4 – Clean the surface with TSP cleaner to remove any trace of grease and oil. Allow the concrete to dry overnight.
Indoor concrete –
Wash indoor concrete with a mixture of bleach and warm water. Follow steps 2 – 4 listed above.
Materials needed to paint over concrete:
– Acrylic primer (for painted concrete)
– Masonry sealer (for unpainted concrete)
– Latex paint for concrete
– Paint roller with extension handle
– Replacement roller heads for textured paint
– Paint brush
- Before you can begin painting concrete, the area will need to be primed to ensure the paint will properly adhere to the surface. If you’re painting concrete that has not been previously painted, apply a masonry sealer first. Painted concrete will require a coat of acrylic latex primer. Allow to dry according to package directions.
- Apply a high-quality latex pain with roller heads designed for textured paint, as they are thicker and more durable when painting rough surfaces.
- Expect to have to paint two coats. If you are not pleased with the way the paint looks at first, be patient. It will look better after a second coat (or more) is applied, and will the paint will darken as it dries.
- Finally, apply a generous coat of masonry sealer to protect the paint from chipping and peeling.
A note about painting over new concrete – If the concrete you want to paint is new or has recently been replaced, you’ll need to wait a minimum of 60 – 90 days to allow the concrete to cure before painting.
