The Advantages of Repairing Your Spalling Concrete With Armor Coating Co.

Do you see cracks and delamination on your concrete surfaces? If so, you want to take timely action. Addressing spalling concrete might seem not seem like a priority but doing it sooner rather than later could save you from a much larger headache.

At Armor Coating Co., we know a thing or two about this type of problem. Let’s discuss everything you need to know about the advantages of repairing your damaged surfaces today.

What’s Spalling Concrete?

Spalling refers to a phenomenon where large pieces of concrete detach from the surface and reveal the underlying aggregate. The most common causes include the following:

  • Freezing and thawing
  • Salt contamination
  • Prolonged moisture exposure
  • Exposure to weather conditions such as intense sunlight, rain, snow, and wind
  • Corrosion of embedded reinforcing steel
  • Poorly applied concrete

Watch out for cracks in your concrete because they point to the first signs of spalling. When left unchecked, they can expand and cause more extensive damage.

Why Repair Your Spalling Concrete?

Timely intervention is the key to preserving your concrete surfaces. By addressing spalling quickly, you will:

Save Money in the Long Run

Spalling exposes the structural support inside your concrete and leaves it vulnerable to damage. Even if only a small portion seems affected, most of the structure actually undergoes decay. Waiting too long to repair can result in extensive repairs or, worse, structural failure.

This leaves no other solution than a time-consuming and costly replacement. Why go through the expense and hassle when a simple repair from Armor Coating Co. can do the job?

Make Your Surfaces Safer

Spalling concrete can become hazardous in several ways when left unrepaired. First, the uneven surface creates a tripping hazard. Second, spalling concrete can cause water to accumulate in the area. This can lead to slippery surfaces, further increasing the risk of injury.

If the affected area gets a lot of foot traffic, repairing the concrete should be a priority. Your home or business will be much safer with a repair from Armor Coating Co.

Improve Visual Appeal

Cracked, spalling concrete destroys the aesthetic of your space. Not only will it make it look old and dingy, but you also can’t effectively paint or seal a damaged surface.

Repairing your spalling concrete protects its structural integrity while restoring its beauty. You can even add a decorative coating to give your space a new look.

Strengthen Your Concrete

Many people opt for repair and protection in one go. This ensures your surfaces get the treatment they need while extending their lifespan. At Armor Coating Co., we offer durable coatings and sealants that provide a strong barrier against corrosion and other environmental elements that can cause spalling.

Restore the Functionality of Your Space

Do you use your concrete surfaces for parking, storage, or other purposes? If so, you’ll want to repair them as soon as possible.

Spalling concrete can slow down your activities and put you at risk of damaging your cars or other items. Repairs and coatings from Armor Coating Co. restore your surfaces to working order so you can continue using them without worries.

Reduce Unwanted Maintenance

After repairing your concrete structure, we also apply a protective coating that reduces the need for frequent upkeep. This new layer only needs sweeping and mopping to retain its cleanliness. Since it helps prevent water absorption, you won’t have to worry about staining or other decay-related problems.

How Does Armor Coating Co. Fix Spalled Concrete?

At Armor Coating Co., we take a methodical approach to repairing spalling concrete in Duluth. Our experts generally follow these four steps:


We gently remove any loose concrete chunks and conduct a visual inspection of the remaining surface. If our techs suspect underlying issues, we’ll also use sounding devices or other testing equipment to get a better look. Structural repairs sometimes become necessary before performing any additional work.

Surface Preparation

With the area fully assessed, we’ll begin preparing it for repair. Our techs typically remove about two inches of concrete surrounding the spalled area for extra safety.

If we see any rebar, we clean it with a wire brush to remove rust and apply a special coating to protect it from further corrosion. Then, we may roughen up the concrete, exposing the coarse texture to help the repair material adhere better.

Repair Spalling Concrete

After prepping the surface, we start filling in the cracks and areas of damage. Our team uses a commercial-grade patching compound that matches the chemical makeup of your concrete. We then smooth the surface of the concrete and let it cure.


Finally, we add a coating or sealant to your repaired concrete slab. This creates an extra layer of protection to prevent spalling and other deterioration. If you want to add a decorative hue or finish, we can also do that for you.
