Here is a great picture of a do-it-yourself log home blasting project. The blaster being used is a relatively small KF100DM Portable Pressure Blaster with a 3/16″ nozzle. Fine Corn Cob Grit is the media being blasted. The objective was to take off the old stain and sealant so that the logs could be re-stained and sealed. I believe the job was completed in one weekend.
