What to Do If Your Concrete Sealer Peels or Chips

Concrete sealers are essential for protecting concrete surfaces from stains, moisture, and wear. However, over time, sealers can peel or chip, leaving unsightly marks and exposing the concrete underneath. If you’re noticing areas where your concrete sealer is peeling or chipping, don’t worry – it’s a common issue and can be fixed. Here’s a guide on why this happens and how to restore your concrete’s flawless finish.

Why Concrete Sealers Peel or Chip

Before jumping into the repair process, it’s helpful to understand what causes concrete sealers to peel or chip. Often, peeling occurs when:

• Improper Surface Preparation: If the surface wasn’t thoroughly cleaned or dried before sealing, the sealer may not bond properly, causing it to peel.
• Over-Application: Applying too much sealer in one layer can lead to bubbling or peeling as it dries unevenly.
• Moisture Issues: If moisture is trapped underneath the sealer, it may push the sealer up over time, resulting in chips or peeling.
• Wear and Tear: High-traffic areas or frequent exposure to elements can wear down the sealer faster, leading to chipping.

Steps to Fix Peeling or Chipping Concrete Sealers

If you notice peeling or chipping, taking quick action is essential to prevent further damage. To ensure a seamless restoration, adhere to following steps:

1. Remove the Old Sealer

To start, you’ll need to strip off the damaged sealer. Use a high-quality sealer remover or stripper designed for concrete. Follow the manufacturer’s instructions, and make sure to wear safety gear like gloves and goggles. Scrub the surface with a stiff brush to help lift any remaining pieces of the old sealer.

2. Clean and Dry the Surface

After removing the previous sealer, thoroughly clean the concrete surface. Use a pressure washer or a concrete cleaner to remove all dirt, dust, and residue from the stripping process. After, let the surface air dry completely after cleaning. Concrete sealers that are applied to a damp surface may retain moisture and cause further flaking in the future.

3. Apply a New Layer of Concrete Sealer

Choose a high-quality concrete sealer appropriate for your specific surface (e.g., driveway, patio, or garage floor). Apply the sealer in thin, even coats to avoid over-application. Follow the manufacturer’s instructions regarding drying time and apply a second coat if necessary. Thin coats help create a stronger bond, reducing the chance of future peeling.

4. Maintain Regularly

To keep concrete sealers in good condition, regular maintenance is crucial. To keep dirt from scratching the sealer, sweep the surface frequently. For outdoor concrete, rinse the surface occasionally to remove any grime buildup. Concrete's life and look can also be extended by periodically resealing it.

Tips for Choosing the Right Concrete Sealer

Not all concrete sealers are the same. To prevent future peeling or chipping, select a sealer that suits your environment and concrete’s use. For example, water-based sealers work well indoors, while solvent-based ones offer more durability for outdoor use. Choosing the right product is key to a long-lasting, protected surface.

Final Thoughts

Concrete sealers are excellent for protecting concrete, but peeling or chipping can detract from the look and strength of your surfaces. By following these steps and using high-quality concrete sealers, you can restore and maintain a beautiful, durable finish for years to come.
