Taming the White Menace: Our Efflorescence Removal Project

Efflorescence on brick can be a real headache, sometimes seeming impossible to remove. We recently tackled a project involving several brick columns covered in this unsightly white mineral deposit, and I’m excited to share our successful approach.

For this particular job, we used EF-Fortless by EaCo Chem. What I particularly appreciate about this product is that it doesn’t require pressure washing for removal. In my experience, pressure washing can sometimes exacerbate the problem. The high-pressure water can force minerals deeper into the brick, and as the brick dries, it draws even more salts and minerals to the surface, leading to more efflorescence. It’s a frustrating cycle! EF-Fortless offered a gentler, more effective solution. 

Understanding Efflorescence

Efflorescence typically appears as a white, powdery substance on the surface of brick, concrete, or other masonry materials. It’s caused by soluble salts within the material that are dissolved by water. This water can come from rain, groundwater, or even excess moisture within the masonry itself. As the water evaporates, it leaves the salts behind, creating the visible white deposit.

Efflorescence vs. Hard Water Stains: A Common Misconception

In our area, we often see white mineral staining on brick siding, and it’s frequently mistaken for efflorescence. While they look similar, these stains are often caused by hard water from nearby sprinklers hitting the brick over time. The minerals in the tap water solidify on the surface, creating a similar appearance. Distinguishing between the two can be tricky, but understanding the source of the moisture is key. Efflorescence is usually linked to water penetrating the brick itself, while hard water stains are more often a surface deposit from an external water source.

Preventing Efflorescence: A Long-Term Strategy

While removing efflorescence is a great first step, preventing its return is crucial. Since efflorescence is often linked to water intrusion, addressing the source of the moisture is paramount. Here are some preventative measures:

• Proper Drainage: Ensure proper drainage around the structure to minimize water contact with the brick.
• Sealants: Applying a breathable sealant can help prevent water from penetrating the brick. However, it’s essential to choose a sealant specifically designed for masonry and consult with a professional for the best application techniques.
• Controlling Water Runoff: For areas exposed to rain, like the columns we worked on, consider adding caps or overhangs to deflect water away from the brick surfaces. This is why you rarely see efflorescence on homes where the eaves provide substantial protection.
• Sprinkler Placement: If hard water stains are a concern, adjust sprinkler placement to avoid direct contact with brick surfaces.

Our Project Success

We’re thrilled with the results we achieved using EF-Fortless. The product effectively removed the efflorescence without the need for pressure washing, minimizing the risk of recurring issues. By understanding the causes of efflorescence and taking preventative measures, you can keep your brick looking its best for years to come.
