When it comes to versatility and durability, concrete walls are the perfect choice for your home, office, or commercial building. A careful process is observed in the construction of concrete walls. From forming to the pouring of the concrete in a wooden frame, this helps ensure the structural integrity of your building. 

Construction is incomplete when walls are not painted with the right kind of paint. In this article, let's talk about how to prepare your concrete walls guide crafted by professional residential painters, how to choose the right paint and tools, as well as some painting techniques for a professional finish.

Preparing Your Concrete Walls

There are different steps involved when preparing your concrete walls. You need to assess the suitability of the surface painting, perform the proper cleaning and repairs in case there are cracks or damage, and finally, select the right primer for perfection. 

Let's dive right into it.

Assessing Your Surface

In order to have a smooth finish and to ensure that the paint application will last long, you need to survey the surface that you are about to paint. You can clean the surface effectively by using tri-sodium phosphate to ensure good paint adhesion. Remove any oils or grease for a smooth finish later on.

Cleaning and Repairs

Proper construction will not guarantee that the concrete wall will be free from cracks and jaggedness. After cleaning, check for the areas that will need repair. If there are any cracks or damages, you can fill them in using a concrete filler or caulk gun. Before anything else, allow the fillers to dry for at least three (3) days.

Next is to smoothen rough areas with sandpaper. Start from the bottom going up to ensure that you cover all areas. Once you have smoothened the uneven surfaces, you can use a vacuum to remove any debris and sand.

Once you are done repairing and smoothening the uneven areas, have a second assessment of the surface and do a final check for any irregularities. Once you have assessed and prepped the concrete surface and ensured the smoothness of the wall, you can proceed with the next best step.

Priming for Perfection

Priming for Painting

Similar to applying makeup, priming is important for a good-quality paint job. There are different kinds of primers available in the market. They are the following:

  • Acrylic/Latex: Water-based or acrylic primers soak into the porous concrete, providing excellent adhesion for paint. They also reduce dust on interior concrete.
  • Polyurethane/Epoxy: Heavy-duty primers that resist chemical attacks and are suitable for commercial or industrial environments.
  • Acrylic Masonry: Designed to protect against lime burn, discoloration, and efflorescence on new or unpainted concrete.
  • Acrylic Block Fill: Ideal for cinder blocks, especially new or unpainted smooth or split-face blocks.
  • Universal Primer: A versatile option that works on various surfaces.

Choosing the right primer for your construction and purpose will lead to better results. If you are unsure which primer to choose, you can always ask for assistance at your local hardware or ask for professional help from a builder.

Choosing the Right Paint and Tools

Now that you have prepared the concrete wall, you have smoothened out the uneven areas and have checked for irregularities, you are almost ready for painting. Shortly, let us talk about how to choose the right paint and tools to ensure a superb painting experience and to achieve fantastic results.

Selecting the Paint

Some of the considerations to make when selecting paint are durability, uses, application and advantages. There's regular paint and there's epoxy paint. 

Regular paint is used for generic protection. It provides some protection but it is still vulnerable to scratches, peeling and fading. While epoxy is known for its resilience and adhesive properties and are better used for high-stress environments. 

For residential properties, exteriors and furniture, regular paint is usually used due to ease of application and aesthetic appeal. On the other hand, epoxy paint hardens once it is cured. It is resistant to impacts, stains, chemicals, and is good for commercial and industrial buildings.
