Looking into buying the festool floor grinder Rg 130 for rubbing down screeds, I currently use a makita eccentric sander but getting bigger jobs then just halls an bathrooms an wanting something I can use in a big loung/diner kitchen but that can also still fit in a bathroom if needed an the extraction unit is a big plus to me as I hate the clean up an a big sanding. Has anyone used one for screed prep? Or does anyone have any other suggestions. Thanks Bruce
