Winter can be tough on concrete. Repetitive freezing and thawing can cause spalding–a term that describes the flaking off of the finished surface of concrete.

While using a sealer can help prevent this process, it isn’t always avoidable. Fortunately, our friends at Concrete Coatings have developed a simple solution for repairing areas affected by spalding.

The Concrete Coatings BroomTek kit has been designed with just this problem in mind. You can see the Demo Video here, but this post will cover the step-by-step process to get your spalding concrete looking beautiful again.

The BroomKit acts much like other overlay products, but the process has been simplified for easy application.

  1. Ensure that the surface area of the spald and the surrounding areas are totally clean. We recommend that the entire work be thoroughly power washed and allowed to dry before anything else.
  2. If the concrete has been either polished or sealed, use an etching product to ensure a proper bond.
  3. Following the mixing procedures, ensuring to allow the mixture to stand 3-5 minutes after the first mix. The standing period allows the mixture to go through the chemical processes necessary for a proper bond. After standing, remix and check for smooth consistency.
  4. Apply the mixture to the affected areas using a squeegee or trowel. Smooth it with a stiff-bristle broom to match the surface level of the concrete.
  5. Allow 4-6 hours dry time before walking, 24 hours for sealing, and 2-3 days for driving traffic (after sealing). All these guidelines vary depending on ambient temperatures (lower temperatures require more drying time).

 

  • If the spalding areas are deeper than 1/4″ deep, BroomTek may not be the proper patching product for you. Contact us for more product recommendations.
  • Be sure to apply your sealer above 50°F and below 90°F.

Removing sealers can be difficult and time consuming. However, a few of our tips can help ease the process and save you some headaches.

Depending on the type of sealer, removal may or may not be an option. Sub-surface sealers such as Lifetime deeply penetrate the pores in the concrete, permanently changing the concrete, and therefore cannot be removed once it has been applied.

Surface-level sealers, on the other hand, can be removed in a few different ways.

If your concrete has been sealed with some kind of acrylic-based sealer, such as our ColorGuard or UltraSeal, removing it with it’s solvent is possible, though this process can be messy and labor intensive. Because it can be difficult, this method is best used for smaller touch-ups and spot removals. Usually these areas will be small and localized problems with cloudiness or other discolorations. We don’t recommend this method if your problem areas are larger than a few square feet.

  1. Apply xylene to problem areas
  2. Let sit for 2-3 minutes
  3. Scrub vigorously until all sealer has been removed.
  4. Rinse areas and allow 24 hours for drying

Once the concrete is fully dry, you can reapply the same sealer. For more info on the application process, check out or post here.

For larger jobs, sandblasting the surface is the preferred method, as it is faster and more effective than other chemical methods. Sandblasters can be dangerous for inexperienced users, and in those cases we can refer an experienced contractor to assist you. Otherwise, most hardware retailers have sandblasters available for purchase or rental.

Removing sealer from concrete can be tricky, especially when trying to maintain the look for the concrete. Sandblasting can etch the surface of concrete, creating visible marks that can detract from its beauty. To avoid this, try to keep the nozzle of the blaster at least shoulder height, and avoid scrubbing an area for an overlong period. Remember: you can always go back over an area again if the first attempt didn’t remove all of the sealer.

There are other chemical agents that can remove sealers from concrete, though these usually suffer from the same issues as the solvent method, and these chemicals are often hazardous to work with. We recommend that if you’re having trouble that you contact us directly with the specific issues you’re having so we can help you troubleshoot the process. Thanks for reading!
