The primary challenge associated with using concrete coating is the potential for it to become damaged or peeled off prematurely. Proper surface preparation is essential before sealing concrete with a coating and if this isn’t done correctly, then the coating may not adhere to concrete effectively and can easily start coming off or peeling away. Additionally, extreme temperature fluctuations, UV rays, and exposure to chemicals can all cause the concrete coating to degrade over time. Applying a top coat of sealant can help protect the underlying coating from the elements but this must be done regularly to ensure optimal protection.
