Dropping a snowplow on any paved surface has the potential of damage or scratching. We recommend the operator raise the plow one inch while plowing. This allows for snow removal without the problem of a heavy steel blade marring your decorative concrete surface. While on the subject, use a plastic snow shovel for walks and patios. While a steel shovel probably won’t harm the stamped concrete, it can scuff the sealer. (Easily fixed by applying another coat of sealer).
