I need to smooth down some acrylic flagstone concrete, which I understand is a pretty tough 5,000 pounds strength per sqft. Which flap discs would be best to use with an angle grinder? (composition?)
I used a diamond grinding wheel, but it goes through it almost like it's butter, both the acrylic layer and the initial concrete base layer. I need a little more finesse for finer smoothing of rough spots and burrs, and so it doesn't leave round wheel marks.probably a diamond grinding wheel. I used one on real flagstone and concrete a few weeks ago and it worked well.
