Cracks on exterior walls can be a cause for concern for homeowners. Not only do they mar the appearance of your property, but they can also lead to more severe structural issues if left unattended. In this guide, we will show you how to restore cracks on exterior walls and provide you with step-by-step instructions on fixing wall cracks.

What causes wall cracks?

Before we delve into the restoration process, it’s crucial to understand the root causes of wall cracks. Here are a few common culprits:

  • Settlement: The natural sinking or shifting of the ground beneath your home can result in cracks on the exterior walls.
  • Moisture: Water infiltration due to damaged gutters, poor drainage, or plumbing leaks can weaken the wall structure and lead to cracks.
  • Temperature fluctuations: Extreme weather conditions, such as freezing and thawing cycles, can cause expansion and contraction of building materials, leading to cracks.
  • Structural issues: Sometimes, cracks can be indicative of more serious structural problems, such as foundation issues or improper construction.

Assessing the severity of the cracks

Before you begin the restoration process, it’s essential to assess the severity of the cracks. This will help you determine the appropriate repair method. Here’s how to evaluate the cracks:

  1. Small hairline cracks: These cracks are usually superficial and can be easily fixed with basic repair techniques.
  2. Wider cracks: Cracks wider than 1/8 inch may require more extensive repairs and could be a sign of deeper structural issues.
  3. Vertical vs. horizontal cracks: Vertical cracks are typically less severe than horizontal cracks, which could indicate a more significant problem.
  4. Cracks with displacement: Cracks that have caused displacement or separation of the wall surfaces may require professional intervention.

Materials and tools needed

Before you begin the restoration process, gather the necessary materials and tools. Here’s a list of what you’ll typically need:

  • Safety goggles and gloves
  • Masonry chisel
  • Hammer
  • Wire brush
  • Concrete or mortar repair compound
  • Trowel
  • Sandpaper
  • Primer
  • Exterior paint

Step-by-step guide to restoring wall cracks

Follow these steps to restore cracks on your exterior walls:

  1. Safety first: Put on safety goggles and gloves to protect yourself from any potential injuries.
  2. Clean the cracks: Use a wire brush to remove any loose debris or old paint from the cracks. Clean the area around the cracks as well.
  3. Chip away loose material: Carefully use a masonry chisel and hammer to chip away any loose material along the crack edges. Create a V-shaped groove for better adhesion of the repair compound.
  4. Apply the repair compound: Following the manufacturer’s instructions, mix the concrete or mortar repair compound and apply it into the crack using a trowel. Make sure to fill the crack completely and smooth the surface.
  5. Allow time for curing: Let the repair compound cure as per the manufacturer’s recommendations. This typically takes around 24 hours.
  6. Sand and prime: Once the compound is dry, use sandpaper to smooth the repaired area. Apply a primer to ensure better adhesion of the paint.
  7. Paint the area: Finally, paint the repaired area with exterior paint that matches the surrounding walls. Apply multiple thin coats for a seamless finish.

When to seek professional help

While minor cracks can be resolved with DIY methods, there are situations where it’s best to call in a professional:

  • Extensive structural damage: If the cracks are severe and indicate significant structural problems, it’s best to consult a professional engineer or contractor.
  • Safety concerns: If you lack the necessary skills, experience, or safety equipment to undertake the repairs, it’s safer to let the professionals handle it.

Restoring cracks on your exterior walls is a crucial step in maintaining the beauty and structural integrity of your home. By following the steps outlined in this guide and knowing when to seek professional help, you can confidently tackle wall cracks and protect your property from further damage.
