I use this two-part clear epoxy called “quick mender” on concrete polishing
It works great! 
We use it after the first grind whether it be 36 or 100 metal bond. 
Add your grinding dust to the epoxy and squeegee it on. 
In 30 minutes you’re ready to start grinding again.

Hello Partners

I did a cement floor and it pitted when I was grinding.

Cleaned out the holes filled it with a tec. Topping coat for the holes.

Did more grinding the next day still pitted but not as bad.

Used the gm3000 and the pitted open up at the very end of the 800 grit.

What is a goodway to fill  the holes?
