What to Do with a Failed Epoxy Floor?
Repairing or Replacing Failed Concrete Coatings
Epoxy floors are renowned for their durability, aesthetic appeal, and ease of maintenance, making them a popular choice for residential garages and commercial spaces alike. However, not all epoxy floors live up to their promises. If your epoxy floor is showing signs of failure, such as bubbling, peeling, sticky spots, or discoloration, it’s essential to address the issue promptly to avoid further damage. In this post, we’ll explore the common reasons epoxy floors fail, how to recognize the signs of failure, and what steps you can take to repair or replace a failed epoxy floor.
Common Reasons Epoxy Floors Fail
Improper Surface Preparation: One of the most critical steps in installing an epoxy floor is surface preparation. Without proper preparation, such as diamond grinding or shot blasting to achieve the correct Concrete Surface Profile (CSP), the epoxy will not bond effectively to the concrete. Many DIY kits and low-cost installers skip or rush this step, leading to premature failure.
Insufficient Cleaning After Prep: Even if the surface is properly prepared, failure to clean it thoroughly can lead to adhesion issues. Dust, debris, or contaminants left on the surface can prevent the epoxy from bonding correctly, resulting in peeling or bubbling.
Cheap or Improperly Installed Products: Not all epoxy products are created equal. Low-quality epoxies often have low solids content, resulting in a thin, weak coating that is prone to wear and tear. Additionally, improper mixing, application in the wrong conditions, or incorrect curing times can compromise the floor’s integrity.
Moisture and Chemical Exposure: Concrete naturally absorbs moisture from the ground, and if the moisture level is too high, it can cause the epoxy to lift or bubble. Additionally, exposure to harsh chemicals, such as oil, gasoline, or cleaning agents, can damage the epoxy if it’s not chemically resistant.
Weather Conditions: Extreme temperature fluctuations or UV exposure can affect the longevity of an epoxy floor, especially if the product used is not UV-stable. Epoxy that isn’t UV-stable can amber, leading to discoloration and a weakened surface.
Signs of a Failing Epoxy Floor
If you notice any of the following signs, it’s likely that your epoxy floor is failing and needs attention:
Bubbling or Blistering: Indicates trapped moisture or air beneath the surface, often due to improper preparation or moisture vapor transmission.
Peeling or Flaking: Commonly results from poor adhesion to the concrete, often due to inadequate surface prep or low-quality epoxy.
Random Sticky Spots: Can occur if the epoxy didn’t cure properly, possibly due to incorrect mixing ratios or application in the wrong environmental conditions.
Discoloration or Ambering: This is usually a result of UV exposure, especially in non-UV-stable epoxies.
Cracks or Chips: These are signs of a weakened surface, possibly due to insufficient coating thickness or exposure to heavy impact or harsh chemicals.
Repairing or Replacing a Failed Epoxy Floor
When faced with a failing epoxy floor, you generally have two options: repair or replacement. The best approach depends on the extent of the damage.
Assessment: The first step is to assess the extent of the damage. A professional will evaluate the floor to determine if it can be repaired or if it needs to be completely replaced.
Repairing the Floor: If the damage is localized (such as small areas of peeling or bubbling), a repair might be possible. This process typically involves removing the damaged area, re-prepping the surface, and applying a new layer of epoxy or a polyaspartic topcoat. However, keep in mind that repairs can sometimes leave visible patches, and there’s no guarantee the issue won’t recur.
Replacing the Floor: In cases where the damage is widespread, replacing the entire floor might be the best option. This involves completely removing the old epoxy, thoroughly re-prepping the concrete surface, and applying a new coating. At Weatherstone Epoxy, we often recommend a polyaspartic topcoat for superior durability, UV resistance, and chemical resistance.
The Importance of Choosing Quality the First Time
When it comes to concrete coatings, it’s always best to invest in a high-quality product and professional installation from the start. While it might be tempting to save money by opting for a cheaper alternative, the costs of repairing or replacing a failed epoxy floor far outweigh the initial savings. Steer clear of companies that rely on business from undercutting the market or that don’t offer a service warranty for at least 5 years. The lack of a service warranty implies that the company is not confident in the quality of their installation and/or product. A professional installation ensures that the surface is properly prepared, the product is applied correctly, and the floor is formulated to last. At Weatherstone Epoxy, we use top-notch products and meticulous preparation methods to ensure that your floor remains durable, beautiful, and functional for many years to come.
In conclusion, if your epoxy floor is failing, it’s crucial to address the issue promptly to avoid further damage. Whether you choose to repair or replace the floor, working with a professional who values quality and attention to detail will save you time, money, and headaches in the long run.
