What to consider before you paint brick

Posted on June 1, 2020

If you have brick inside or outside of your home, you might think there is little to do to update it. While it’s a timeless and earthy architectural element, it can date a room and cause it to feel old. Whether it’s a fireplace or brick on the bottom of your exterior, you are only limited by your imagination. Stains and paints have been created to work well with the porous material. Use colors to bring new life to your bricks.

Many people assume changing the brick is as simple as painting a wall. The job is a bit more intricate than that. In addition to basic painting skills and tools, you must know that there are five things to consider before taking on this project.

Painted brick is relatively permanent

Most of the time, painting can be changed and removed fairly easily. With brick, this isn’t the case. To put brick back to its natural state after painting, you’ll have to go through a complete restoration process. This sort of process requires specialized knowledge, tools, and products. Before you decide to paint your brick, be fully prepared to commit to the color and choices you make. Restoration can be cost-prohibitive for many homeowners.

Root causes of water damage must be detected and prevented

You must look for signs of water damage or intrusion before starting. Damp spots, mold, peeling paint, or any other water-based issues are signs of an underlying issue. Adding paint over it will only seal in the issue and cause bigger damage to occur. This can also damage the paint you put on by causing it to peel and fall off. If your bricks are damp, work with products that will allow the masonry to continue to breathe and allow the water to escape. Consult with professionals if you have any concerns about underlying water issues before you begin this project.

Efflorescence is a common problem in brickwork

Inside the brick and mortar are water-soluble salts. As the water evaporates, the salt stays behind on the walls creating an efflorescence. This happens when the bricks aren’t sufficiently prepared before a finish or sealant was applied. Our painters are experienced in dealing with correcting problems from previous paintings. They also are well versed at preparations before painting or staining brick to avoid future issues. For example, it’s imperative to inspect and clean masonry before beginning work. Our teams know this and will not cut corners on your projects.

Excessive alkalinity can damage the paint

When painting brick, alkalinity can also damage the final results. Bricks are typically neutral but the mortar around them contains soluble mineral salts, which are alkalis. Free alkalis will lead to the disintegration of oil-based paint and films. This process is called saponification. Applying the appropriate primers can prevent this sort of failure in paint.

On-going maintenance is necessary

Painted brick will require regular maintenance. Keeping your painted bricks in good condition will provide protection against failure and the elements. When working outside, taking UV Rays into consideration is important. Once the paint begins to fade, you’ll need to consider repainting to protect the walls. One way to avoid frequent repainting is to prime appropriately and use a light color. Consider colors like off-white, cream, eggshell, or other white versions.
