Top-Rate Paints For Concrete Walls | Buyer’s Guide
Choose the appropriate solution
If there is one thing that puts buyers in a confusing loop is the choice of buying concrete paint or a concrete stain for the job.
So, is paint or stain better for concrete? They both have their merits and demerits. So, let’s take a look at them below:
Read Also: Stained Vs Painted Cabinets
There are two types of concrete stains namely water-based and Acid-based stains.
Water-based stains are fast-drying and easy to clean on the concrete. Accordingly, they require the use of sealant after application to prevent fading. It demands more than one coat of stain if you want to strengthen the color.
Meanwhile, Acid-based stains work by penetrating the surface and reacting chemically in the concrete. Once dried, it becomes a permanent part of the concrete and won’t peel away, neither will it fade off.
Consequently, they are hazardous and cause severe eye, skin, and lung irritation. Therefore, the use of heavy gloves, face masks, as well as protective gear is compulsory.
Concrete paints are expensive, although they offer the versatility and performance needed to perfectly protect the concrete surface against crack, chemicals, and natural elements.
Furthermore, they work on both interior and exterior applications.
However, it requires hectic prep work like clean it with degreaser (to remove any oil or grease stains), plus the use of muriatic acid (to remove any curing chemicals on the surface) before painting.
Remember, Muriatic acid is hazardous if inhaled, and prolonged exposure causes circulatory failure. For this reason, endeavor to go through all the instructions before working with muriatic acid – if you’re using it.
Look for a Proofing Solution
Use paint that is both waterproofing and chemical acid-resistant. Why? Because they’re capable of withstanding leakage, UV radiation, and physical abuse that might result in peeling or creaking.

How to Paint Concrete Walls
Below is a step-by-step guide on how to paint concrete walls:
Use a concrete patch compound to fill in all gouges, holes, or scratches. Then allow the filler to seat in, before sanding the repaired areas until they are smooth.
Use a Trisodium phosphate (TSP) and warm water to clean the concrete surface thoroughly –removing all dirt, oil, and grease that might ruin the bonding process or cause discoloration.
Use a metal-bristled brush to apply the solution. Before that, you should read the package instructions to ensure the proper ratio of TSP to water.
Lastly, Trisodium phosphate is harmful when it makes contact with the eyes and skin. So, be sure to throw in full protective gear before handling TSP.
Let the surface dry before you start painting. Subsequently, you likely to see a slight bubbling across the surface as the TSP reacts with the concrete.
Don’t chicken out, it’s normal. At this stage, you should let it bubble for 20 minutes, then hose the TSP down.
Secondly, let it dry for two days before painting. When it dries, it should feel like a 120-grit sandpaper area when you run your hand over the concrete.
First thing first, wipe the area down with a dry cloth or sweep it. Then it is paint time!
I often use the best paintbrush for walls to paint over the perimeter of the surface, because it gives me maneuverability to achieve excellent coverage when painting around edges and corners.
Use a roller for covering vast portions of the concrete
Sand or scrape away any protruding bumps or lumps that appears from the first coat. Then sweep the areas again.
Apply the second coat, but only this time, press the roller down firmly to mash the paint into the concrete for deeper penetration. Lastly, let the second coat dry for 3-5 days at maximum.
