I'm considering purchasing the Festool Rotex RO 125 FEQ. This purchase would replace a grinder and random orbital sander.
My immediate need would be to strip a 2 part epoxy paint from a concrete floor and etch the surface. By "etch" I mean make the surface of the concrete coarse so I can apply a different 2 part epoxy paint. The coarse surface is needed to form a mechanical bond (a lack of a mechanical bond is the whole reason I need to strip old epoxy).
Using a grinder/sander with dust extraction is WAY MORE preferable to using methylene chloride to strip the old epoxy and phosphoric acid to etch the concrete.
After this project is over I would use the ROS function on wood mostly.
Is the Rotex up to the task I need for my concrete floor or would I be better off renting a grinder for a couple of days?
