I am looking for a mastic remover for asbestos containing coal tar removal
The majority of coal tar will be removed with an abatement contractor but the residue is still left after scraping on a 52" steel main installed in the early 70's. We need all the residue off of the steel to weld to. What mastic removers, or cleaners have been used with success in your place of work. This work will have to be doing this in a confined space so vapors are a problem.
