DIY Home Improvement: How to Paint Over Concrete

Concrete surfaces, both inside and outside the home, can take on a dull grey appearance over time and cause the area around it to look dark and dreary. To combat this common problem, concrete surfaces should be frequently cleaned and painted over for decorative purposes. 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 listed below to paint over concrete. We’ve included easy-to-follow instructions needed to properly paint over concrete.

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- Co
ncrete patch
– Bleach and water solution
– Bucket
– 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

STEP 1 – 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.

STEP 2 – Paint concrete with a high-quality latex paint. To apply the paint, use roller heads that are designed for textured paint, as they are thicker and more durable than thinner types. Use a paint brush to get into corners, to paint around edges, and so on.

STEP3 – When you paint over concrete, you can expect to have to apply a minimum of two coats of paint. 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.

STEP 4 – Finally, apply a generous coat of masonry sealer to protect the paint from chipping and peeling.

A note about painting over concrete that is new – 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.
