Sandblasting can be an effective way of removing old finishes like paint and creosote from log homes. Sandblasting typically utilizes silica sand as an abrasive and high pressure to mechanically remove away the old finish or dirt. Upon completion of the sandblasting, all wood surfaces that have been sandblasted will need to be sanded down to reduce the mild abrasion that occurs. The severity of pitting that can occur or is dependent on the species and condition of wood being sandblasted and the amount of pressure used. Typically, a diesel compressor capable of 185 CFM (cubic feet per minute) is required. Always wear adequate protective gear (face shield, thick gloves and clothing, and a respirator) when sandblasting.

Crushed glass works like millions of tiny surgical steel blades, making short work of old coatings, paint, stains, as well as UV-damaged wood. It leaves the healthy wood underneath undamaged and creates a slightly textured surface for improved stain adhesion and longevity. Finish sanding with our Osborne Brushes or Surface Conditioning Discs can be done afterwards to reduce wood texturing.
Cob blasting is another environmentally friendly way of removing old finish from log homes using ground dried corn cobs. Cob blasting generally isn’t as destructive to the logs and wood as sandblasting. Upon completion of the job used the corn media can often be used as biodegradable mulch around the garden. Sandblasting usually involves hauling the media away after use, which can be an added expense. Some people claim that the biodegradable corn cob may be responsible for mold and fungus growth within the log once the job is completed. Proper washing with Log Wash and application of a quality borate product like Shell-Guard RTU will eliminate any fear of mold growth.
A light sanding with an Osborn Brush or Surface Conditioning Disc is all that is required after cob or media blasting. This ensures uniform and proper absorption of stain. Irregular surfaces can be finished with Prelude before Lifeline Exterior or Ultra-2 to ensure proper color.
