Are you wasting your money or will sealcoating fix your asphalt?
Sealcoating is a popular method for maintaining asphalt surfaces. It involves applying a protective layer over the asphalt to shield it from the elements and enhance its appearance. But is sealcoating truly effective in extending the life of your pavement, or is it just a cosmetic fix? Let’s dive into the benefits and limitations of sealcoating to determine its actual effectiveness.
Benefits of Sealcoating
Sealcoating offers several advantages that make it an attractive option for asphalt maintenance:
- 1Protection from the Elements: Inevitably, asphalt will be damanged by UV rays, water, and chemicals. Sealcoating should as a barrier, preventing these elements from penetrating the surface and causing deterioration.
- 2Improved Aesthetics: A freshly sealcoated surface looks new and well-maintained. This can enhance the curb appeal of your property and create a positive impression for visitors and customers.
- 3Cost-Effective Maintenance: Regular sealcoating can delay the need for more extensive and expensive repairs by keeping the asphalt in good condition. It can be a cost-effective part of an overall pavement maintenance plan.
- 4Easier Cleaning: Sealcoated surfaces are smoother, making them easier to clean and maintain. Oil spills and other stains are less likely to penetrate the surface, making them easier to remove.
The Limitations of Sealcoating
While sealcoating has its benefits, it is not a cure-all solution for asphalt maintenance:
- 1Minimal Structural Repair: Sealcoating does not address underlying structural issues. If the asphalt base is compromised or there are significant cracks and potholes, these problems need to be repaired before sealcoating.
- 2Frequent Reapplication: To maintain its protective properties, sealcoating must be reapplied every couple years. This ongoing maintenance can add up in cost over time.
- 3Skin-Deep Protection: Sealcoating only protects the surface of the asphalt. Deep cracks and alligator cracking (a type of damage resembling the skin of an alligator) require more comprehensive repairs.
