Which machine?

[Hogan's Hero]

My floor has just cured and I am ready to start prepping for epoxy. I have fibers in the pour so I have to get rid of them. I went to the rental place today and now have several options, and am not sure about any of them. They have a "grinder" which is attached to a floor buffer which seems to be the best option. I am not sure however if the 100 grit blocks will get rid of the fibers that are on the surface...what sayeth the collective?

Oh yea...I can also get the same machine with sandpaper or screen and of course the diamond grinder which I don't need as the floor is not sealed.

I used a propane torch to get rid of my glass fibers that were exposed. It took all of 15 mins to sweep the flame across the floor.

A grinder may get the fibers that you have exposed, but it will also expose more as it takes the top layer of the concrete off. I think VC has the a great solution that should solve your razor stubble problem.
