Maintaining high-traffic floors is a challenge, even for professionals. High-Traffic Floor Polish is specially formulated to seal and protect vinyl and other hard surface floors. Simply apply with a string mop for a gloss finish that resists scuffs, heal marks and slipping. The low-VOC (less than 1 percent) product requires little maintenance and is intended for use on interior floors such as rubber, asphalt, vinyl and sealed concrete. Polish is step 3 of the Zep 4-step floor maintenance program.
