Refinishing can enhance your bathtub’s look and durability greatly but does not have a specific function to get rid of mold and mildew. However, the cleaning and preparation involved before refinishing can help in dealing with minor molds and mildew. In case of extensive mold conditions, more remediation may be required after the completion of this service; Additionally, once refinished, it creates an unfriendly environment for future mold growth as its surface becomes smooth and non-porous thus contributing towards the cleanliness of the bathroom.
