Hello, I'm a new member. I removed tile in my kitchen, (10'x15' area), and found that the thinset put down is from 1/8" to 3/4" thick. I'm wondering if a "concrete prep tool with a Diamabrush removal tool" from Home Depot will be sturdy enough to do the job? I coulsn't get a straight answer from the guys at HD. Thnaks.
