I am looking for a portable disc sander that I can use to help remove a finish from a concrete kitchen countertop. (I’ve done it before, so I know it can be done.) I will be using water as a lubricant, so the process will be messy. When I did it the last time, I used my trusty Porter-Cable random orbital palm sander, but that was a smaller area. My concern (frankly, I didn’t think about it then) is insulation — obviously one is generally hesitant to use power tools around water.
I don’t need a heavy duty “water sander” that connects to a hose and constantly feeds water. Is there any reason I can’t use a good Makita, Hitachi, PC, Milwaukee or Bosch disc sander and just keep it away from water? Maybe wrap a rag around the motor to avoid splashing? Or will that cause the motor to overheat?

you CAN do that..but a better way is a cheap RO air powered sander..Harbor Freight has em..6" for about 50 bucks IIRC..any auto body type place has em too..I like the SOUIX (SP?) 5'' ..

USE A VARIABLE SPEED GRINDER TURNED ON LOW WITH DIAMOND DISCS. A SPONGE SATURATED WITH WATER THAT IS SQUEEZED OCCASIONALLY WILL GIVE YOU ENOUGH WATER TO LUBRICATE THE DISCS. THIS WILL SPEED THE JOB UP CONSIDERABLY. MAKE SURE YOU PLUG INTO A GFCI AND YOU'LL BE FINE
Isn't the cord on the PC a two-prong? That means it's double insulated, and the case is plastic too. Plug into a GFI and have at it.
