Dark interiors have emerged in the design landscape for the past couple of years. People fell in love with the boldness and mystery of black that what started as merely a black accent wall now covers almost the entirety of their homes. But while it has its own appeal and advantage, one can simply have a change of heart. If you’re here because you’re about to paint over your dark walls, I suggest you take notes.

We have already written a step-by-step guide on how to repaint concrete walls but one question popped up: what if you want to repaint your dark walls with a lighter color? Boysen professionals suggest adding one simple step: The application of white primer.

Watch Out for Common Painting Problems

Generally, preparing concrete walls, whether light or dark-colored, are one and the same. First, you need to check if the surface has problems, then you need to troubleshoot as soon as possible. Click on the photo to know what you have to do when your wall has the following conditions:

The term ‘chalking’ in painting refers to the deterioration of the paint system resulting to the appearance of a loose powdery substance on the wall.

In most cases, peeling is an aftermath of an unresolved case of blistering. After the paint creates bulges on the wall due to the lack of adhesion, it starts to come off in strips and bits – that’s peeling.

Flaking is the delamination of the paint system from the wall. It appears as patterned flakes or scales and unlike peeling, it is more brittle.

In basic terms, mildew or mold is a form of fungus that lives mostly in a damp, starchy and acidic environment, and is prevalent in tropical countries like the Philippines.

Prepare Your Walls the Boysen Way

While it is innate in most of us humans to save whatever we can, when the gravity of the painting problem has become severe, you have no choice but to start again. I mean, scrape off all the paint manually or if necessary, use Boysen Paint and Varnish Remover B-141. On the other hand, if there is no issue that needs to be resolved, you’re good to go. Wash the surface clean and wait for it to dry. Next, sand the surface to remove bumps. Aside from smoothening out imperfections, sanding also helps in better paint adhesion.

Darker-colored walls are harder to cover especially if you’re repainting it with a lighter color. The trick is in the primer. Once you’re done with sanding, apply Boysen Permacoat Flat Latex B-701 using a brush or a roller. It has excellent hiding ability that instantly conceals the existing paint making the application of a topcoat so much easier since you don’t have to worry about the previous paint color affecting the new one. Boysen Permacoat Flat Latex is ideal for interior and exterior surfaces such as concrete, bricks, plaster, and drywall.

If you’re still not satisfied with the evenness of the wall, apply Boysen Masonry Putty B-7311 on interior areas with minor flaws and Boysen Acrytex Cast B-1711 on exterior surfaces. Watch this Boysen guide to help you in your DIY journey.

Give your walls the care and love it deserves by making it over every once in a while and ensuring that it stays beautiful and fresh.
