I have a customer/friend that wants us to blast glue residue from her concrete porch. They had glued carpet down and the glue has almost become a part of the concrete it is so hard. Any suggestions? I was thinking fine crushed glass but I am afraid of the dust just being overwhelming. They have it on their front porch and their side entrance little porch, both are concrete.

If your going to blast the concrete just use a water ring attached to your blast nozzle. This will help to keep the dust down. It makes a muddy mess but it is better than all the dust. Have you tried pressure washing to see if the glue would come up. Might take 4,000 to 5,000 psi. If you blast the concrete then the concrete will have to be sealed afterwards.

I have not tried to pressure wash it, I figured I would ask the experts and see what sounded like the best suggestion before I did anything.

Use a pearl disc on an electric floor buffer, it will scrape that stuff off easily. I used one to remove glue, and also epoxy from a floor to prepare for a new overlay. They tear old glue up with ease. and you can usually find them at any rental house.
