Problems When Painting Brick: A Comprehensive Guide by Rhino Shield

Written by admin | Jul 16, 2024 3:45:00 PM

Have you ever looked at your brick home and thought about giving it a fresh coat of paint? Maybe you've noticed some areas looking a bit worn out, or perhaps you're just ready for a change. But as you delve into the task, you might quickly realize that painting brick isn't as straightforward as painting other surfaces.

 

Here at Rhino Shield, we understand the unique challenges and questions that come with painting brick. "Can I paint over old, crumbling mortar?" or "What do I do if my bricks are glazed?" These are common concerns we hear, and in this guide, we'll address these and more, ensuring you're equipped with the knowledge to make the best decisions for your home.

 

Evaluating Mortar Health Before Painting

Before you even think about choosing a paint color, it’s vital to check the health of your brick’s mortar. Old, decaying mortar can turn a new paint job into a homeowner's nightmare. Why? Because if the mortar is in poor condition, painting over it might just be putting a Band-Aid on a much larger issue. At Rhino Shield, we recommend a thorough evaluation by an expert. This is crucial because healthy mortar is the backbone of any successful brick painting project. Here's what could happen if you overlook this step:

  • Long-term durability issues: Paint might initially hide mortar problems, but these issues can resurface, affecting both the appearance and integrity of your brickwork.

 

The Risks of Sealing Weep Holes in Brick

Another common mistake is painting over the weep holes—small openings at the bottom of brick walls that allow moisture to escape. Sealing these can lead to moisture getting trapped inside the brick, which over time can damage both the brick and the mortar. Remember, these holes are there for a reason:

  • Prevent moisture buildup: Ensuring weep holes are clear can prevent structural damage and maintain the health of your brick facade.

 

Challenges of Painting Over Glazed Brick

Glazed brick, with its shiny, protective coating, poses its own set of challenges. These bricks are beautiful but tricky when it comes to painting. At Rhino Shield, we often encounter homes where previous paint jobs on glazed bricks have failed because the paint simply doesn’t stick well. If you're dealing with glazed brick:

  • Professional consultation is key: Our experts can advise whether painting is feasible or if the glazing makes it a no-go.

 

Importance of Cleaning Brick Before Painting

Cleaning the brick surface thoroughly before painting is essential. Brick is porous and can absorb a lot of moisture, which often leads to mold or algae growth. If these aren't cleaned off properly:

  • Poor paint adhesion and potential damage: Trapped grime can lead to paint failure and even damage the brick over time. Always start with a clean slate for the best results.

 

Choosing the Right Products for Brick Painting

Rhino Shield offers two great solutions. The first is our standard popular Rhino Shield ceramic coating. This helps seal the bricks, keep out moisture, reduce wall temperatures, and comes in any color you want.

 

The second option is brick sealing with our Rhino Shield clear coat. This option is for brick building owners who do not want a painted brick look. The Rhino Clear helps rejuvenate mortar, offers water resistance, and helps the building stay clean, leaving you less likely to accumulate mold, mildew, and dirt. This option is popular in New York City. The city has a lot of older brick apartment buildings that get dirty and dull. Rhino Clear has helped protect them and provides a clean, glossy look.

 

Selecting the correct primer and paint is crucial for a lasting brick paint job. At Rhino Shield, we’ve developed a specialized primer that not only adheres well to brick but also enhances the durability of the mortar. Here’s why choosing the right products matters:

  • Extend the life of your paint job: With the right primer and paint, your new color will not only look great but also last much longer, even on challenging surfaces like brick.

 

When to Call in the Experts

While DIY projects can be rewarding, some tasks are best left to the professionals—especially when it comes to something as permanent and prominent as your home’s exterior. Hiring a professional painter ensures:

  • Proper assessment and application: An expert can identify potential issues before they become major problems and ensure that the paint is applied correctly.
