Why Do We Cob and Sand Blast vs. Power Wash?
Sand or cob blasting has a number of advantages over power washing. The process of removing a finish from the logs is, simply put, a matter of throwing something at the building at a certain velocity (or pressure) that is sufficient enough to take off the finish while causing as little trauma as possible to the logs. Blasting is a dry process. When dry, the surface of the finished logs is somewhat brittle. When the dry logs are hit with the sand or cob media, the brittle finish is quickly and efficiently removed leaving the logs relatively smooth.
