in my basement which is being renovated i would like to leave a brick wall exposed, however there is old (lead-based, 100%) paint on them. what is the best way to go about removal ? pressure-washing ? or just regular scrubbing ? if the former, how does one go about collecting the rinsed run-off considering that is indoors or is there just no way around the messiness of the project ?
The only process I know of that will work for this project (removing paint from brick and leaving the brick intact and attractive), is water/media blasting
It's done inside with the area taped off with plastic
A combination of media and water blast off the paint, and leave the bricks
I don't know the rules about lead with this, but I suspect as it's wet (no dust), that it's OK for lead paint also...if the technician/company is certified
The process, however, is not DIY friendly
Although there's much you could do to prepare the room (you'll really want it pretty empty), the actually blasting should be done by a pro
