Is It the Sealer or the Brick Flaking?

One common issue that homeowners encounter with their brick surfaces is the phenomenon of flaking. This perplexing problem can leave them questioning whether it’s the fault of the sealer or the brick itself. Determining the root cause is crucial for finding an effective solution, whether it lies in faulty application of sealant or inherent flaws within the brick material. By examining the characteristics of the flaking and closely monitoring the condition of both the sealer and the brick, homeowners can gain insights into the true perpetrator of this disheartening issue.

How Do You Know if Brick Is Sealed?

Another method to check if a brick is sealed is to pour a small amount of water on the surface. This is because sealants create a barrier that repels water and prevents it from being absorbed by the brick.

Additionally, you can inspect the color of the brick. When bricks are sealed, they tend to have a slight sheen or shine to them. This is due to the protective layer of the sealant. Unsealed bricks, on the other hand, appear dull and matte in appearance.

Furthermore, you can also look for any signs of efflorescence on the surface of the brick. Efflorescence is the white, powdery deposit that’s formed when water evaporates and leaves behind salt deposits. If a brick is sealed, the sealant will help prevent the accumulation of moisture and subsequent efflorescence.

Another indication of a sealed brick is the absence of moss or algae growth on it’s surface. When bricks are unsealed, they can provide a suitable environment for the growth of these organisms. However, a sealed bricks protective layer makes it less favorable for moss or algae to take hold.

Lastly, if the brick has been recently installed or if you’ve the documentation from the builder or previous owner, there may be information about whether the bricks have been sealed. This can be particularly helpful if you’re unsure about the appearance or feel of the brick, as the documentation will provide a definitive answer.

How to Properly Seal Bricks

  • Prepare the bricks by cleaning them thoroughly.
  • Inspect the bricks for any cracks or damage.
  • Apply a layer of brick sealer evenly on each brick using a brush or roller.
  • Allow the sealer to dry completely before applying a second coat if necessary.
  • Check for any missed spots and reapply sealer if needed.
  • Let the bricks cure for the recommended time mentioned on the sealer’s instructions.
  • Inspect the sealed bricks to ensure they’re well protected.
  • Regularly maintain and reapply sealer as needed to keep the bricks protected.

This treatment will help prevent further water infiltration and protect the bricks from additional damage.

The Importance of Proper Drainage to Prevent Brick Flaking

  • Proper drainage is crucial for preventing brick flaking.
  • Without adequate drainage, water can accumulate behind brick structures.
  • This trapped moisture can lead to the degradation of the brick material.
  • When water seeps into the brick, it causes a process known as spalling.
  • Spalling is when the brick’s surface starts to flake, chip, or even peel off.
  • Proper drainage helps to prevent water from getting trapped behind the brick.
  • One way to ensure proper drainage is by installing a weep hole system.
  • A weep hole is a small opening that allows water to escape from behind the brick.
  • Another method is to use a moisture barrier, such as a waterproof membrane.
  • This barrier helps to redirect water away from the brick, preventing moisture buildup.
  • Maintaining proper drainage also involves regular inspection and maintenance.
  • Clearing gutters, downspouts, and drains of debris can help prevent water buildup.
  • Additionally, grading the surrounding landscape away from the brick can aid in drainage.
  • Overall, proper drainage is essential for preserving the integrity of brick structures.
  • By preventing moisture buildup, it helps to prevent brick flaking and deterioration.

If the deterioration of your bricks is more severe, DIY methods such as sealing may not be sufficient. It’s important to note that simply sealing your bricks won’t address the underlying issue causing the damage. In cases where serious water damage is suspected, it’s advisable to seek professional assistance for the best results.

Can You Seal Crumbling Brick?

If you’ve noticed that your bricks are starting to crumble, it can be a cause for concern. While mild crumbling can be addressed with a sealer, it’s important to note that more serious spalling can’t be effectively handled with DIY methods. Sealing the bricks won’t fix the underlying cause of the issue either.

Before attempting any sealant application, it’s crucial to determine the root cause of the crumbling. If you suspect that serious water damage is the culprit, it’s best to seek the assistance of a professional. They’ll be able to assess the situation accurately and provide appropriate solutions to address the underlying issue.

Sealing a brick surface that’s mildly crumbling can be a temporary fix to stabilize the bricks. However, it’s important to understand that this isn’t a long-term solution.

If you choose to apply a sealer to your crumbling bricks, make sure to follow the manufacturers instructions carefully. Typically, this involves thoroughly cleaning the bricks, allowing them to dry completely, and then applying the sealer evenly. It’s important to note that sealers can alter the appearance of the bricks, so it’s recommended to test a small, inconspicuous area before applying it to the entire surface.

It’s crucial to identify and address the underlying cause of the issue, particularly if serious water damage is suspected. Seeking professional help is advisable in such cases to ensure the problem is properly resolved and to prevent further damage to the brickwork.
