Should I Use a Prep Solution or Grinder to Prepare the

Aug 14, 2016 Should I use a prep solution or grinder to prepare the floor? Mechanical grinding methods are hands-down the best way to prepare a concrete floor for any epoxy application. They are best because they are able to profile the floor more aggressively than prep solutions. Three common grinding tools are shot blasters, scarifiers, and grinders.
