I have a building that is actually two adjoining buildings under one roof. This means that I have a large brick wall in the middle. I actually like having the brick there, but I would like to clean it. Is it possible to sandblast the interior walls? What issues do I need to take into consideration? If sandblasting isn’t an option, are there any other suggestions for cleaning the walls? One wall is 270 sq ft, so a wire brush isn’t really an option.
Note: everything is unfinished, so I have no framing to worry about and only subfloors.
There truly is no difference in the process whether done outdoors or in. Especially inner city issues require that a ROOM/Shielded space be set in the area of the blasting. That might be accomplished with Tarps over framework in your case.
The blast operator most often wears protective OVER clothing, and certainly a mask/respirator, as well as a helmet of some sort. Containment is the issue, not the effectiveness of the task.
