In the renovation of the green show house we are exposing as much brick as possible instead of building walls over it since the greenest building is no building. But the walls were not intended to be seen and a lot of them are in bad shape.
The normal thing to do is was the walls with acid. This means buying more products, and very corrosive ones at that. So I did a cost analysis and once again decided that paying my workers to work a little more was more cost effective than going the fast route and buying the acid wash.
The price is pretty much the same for me, only the money goes to the workers instead of the acid wash company, and I don’t put more acid into the environment.
The irony is that a little elbow grease on the walls makes them look a lot nicer than the acid wash (we did a little test with the acid wash to be sure we were making the right choice).
