1) Be prepared for some dust in your home. When cob blasting a home, if there are gaps in which air can come in, then its likely some cob will come in as well. If the house is well sealed, this may be a very minimal amount. However, if your home is not sealed well and there are numerous gaps, it could be a fair amount of dust. The good news is that it is light weight and vacuums up easily rather than water or chemical strippers that can cause all sorts of damage to the interior walls and floors.
2) If you are planning new landscaping around the home, it is best to wait until after blasting and sealing the home. While we try to catch as much of the spent blast media as possible, it is impossible to catch it all. Since it is 100% natural, it will mix in with the lawn/mulch rather quickly, but its easier to do your landscaping once rather than having to do it twice.
3) Have all light fixtures, signs, address numbers etc. removed before cob blasting. This will save a great deal of time for the blaster.
4) Realize that stain and sealer takes differently to each log. While cob blasting gives a generally uniform look to the home overall, there are areas and spots (mostly around knots) that the stain may not come off completely. Also, areas that are not subject to sun and weathering (i.e. porches, overhangs, etc.) may remain somewhat darker than areas that are subject to the weather. However, when a new stain is applied, the difference is not usually evident.
5) Understand that restoring your log home is a process. The time it takes to blast your home and then to have it stained and sealed depends on several factors. Certainly the size of the home is the single greatest factor, but other factors include the type, quality, and condition of the finish currently on the home, and the weather (rain delays stink!). Keeping these things in mind, the blast process alone can take anywhere from a couple days to a few weeks and then the home still has to be stained and sealed. The good news is, when done right, you shouldn’t have to have your home blasted again for a long, long time.
