Best Paint for Exterior Concrete Walls Buying Guide

Best Paint for Exterior Concrete Walls

When purchasing the best paint for exterior concrete walls, here are a few things that you must keep in mind.

Intended Usage

When choosing paint, it is important to consider its intended use. For example, some paints may not work well outdoors as they will indoors. And so, for exterior concrete walls, you must choose exterior-grade paint.

Most concrete paints available on the market are typically exterior/interior paints, but you must be sure that the paint you purchase will work well outdoors. Also, some paints do not work very well on vertical surfaces.

For example, epoxies and floor paints are usually heavy and tend to run down the wall before they dry, causing running, streaking and uneven coats. So, for exterior concrete walls, you must make sure to choose a concrete block/brick or wall paint.

Weather Resistance

Your exterior walls are usually exposed to the harsh UV rays of the sun and the elements, which can cause the paint to fade and crack.

To prevent this, and ensure that your paint doesn’t wear, choose weather-resistant paint. Exterior-grade wall paints will hold up longer and need fewer repairs and touch-ups.


Concrete wall paints come in a range of finishes, from gloss to matte. Matte paints tend to hide dirt and flaws better than gloss paints and this is especially beneficial for exterior concrete walls.

When shopping for exterior concrete paint, it is a good idea to determine the finish of the paint and choose one that suits your personal preference best.
