The shot blaster we used was very maneuverable: Think two large shop vacs connected together.
We only used it once to remove cutback asphalt adhesive over slab that had radiant heat.
Check with any number of rental outlets. They will have hourly or daily fees. Not expensive.
Be aware:
1. The blaster will not get in tight areas or close along walls.
2. If you sit in one place for too long with in blasting you will start to bore a hole in the slab.
Those 'flakes' they broadcast into epoxy garage floors aren't just for decoration!
They cover up all the funk they create.
The key to a good mechanical bond is the porosity of the surface you intend to apply to.
Like I said, rinse several times after using the adhesive stripper.
Then let it dry. Take a wet sponge and wipe over a test area. If it turns 'dark', water is penetrating. Your paint will too!
This is also good test to see if your grout/stone sealer is still effective. If it doesn't turn dark, or better yet, the water beads up, it's still working.
Get to work!
It will take you about six hours... and less beers!
