How to remove residue from conc. slab floor.
by
Larry
I have removed old vinyl tiles from my kitchen floor. They were stuck to the conc. slab with some sort of black mastic type material. It is hardened and won't scrape off. I will be replacing it with ceramic tiles for our new kitchen floor and want to make sure it has a good clean and flat surface to apply them to. Any idea how to remove the stuff? Or maybe I could leave it and just level the tiles as I place them?

Try heat gun and your scraper.
Yoh may have to get a solvent based cleaner to remove the gluE. That stuff can be pretty stubborn to remove. Check with your local paint or even flooring store, 5hey could tell you what will work.
