Hi Guys. I have posted this also on another site to be honest.
Just looking for help. Last year I bid on a job to remove mortar blasted all over a section of a building . 100 feet by 4 stories to be cleaned .the building is 12 + stories big money building . Lots of people traffic a real nightmare.
Now a year later I get the ok . I put a lift to work I am using nmd-80
7 hours later I am making no headway the mortar will not break up .
Any suggestions on something different to use. I have used it 3x1 2x1 and straight. I have used pressure and hot water. I do not want to damage the limestone . Any help is a great help
Thanks
