No ideas on this one, other than building scaffolding with innumerable blocks underneath to make it safe. Sorry but good luck
We have a project that requires cleaning a glazed brick wall (was the subject of a past thread), and I think we have the situation under control Except there are some high wall areas (12-18 ft high') on either side of high windows on stair landings. These areas are not easily reached by ladders due to the precariousness of the situation, a cherry picker won't work and we can't build scaffolding. Was wondering if anyone has used a device for reaching high areas like this without too much trouble. We have a Whissper extractor but the wand isn't that long. the wall has efflourescence in addition to standard grit and grime. See photo below. Thanks much, Baird
