Don't waste your money on the concrete cleaner. Didn't work well for me.

This project is just kicking my arse.

I was reading the label on the RadonSeal Standard. Said if the concrete had been power trowled, I would need to etch it first. So, bought four gallons of the power etch. Started on that Saturday, but four gallons only did half my workshop area (about 1350 feet). The etch did work well, and the surface was noticeably rougher, ready to receive the sealer. The sealer is a siliconate penetrating sealer.

Followed the directions with Sherri's help. Only thing I didn't do as directed was to "rinse". I wasn't sure if rinse it off meant a hose, but I wet mopped it off. What was left is a chalk looking residue. It is very hard. I went over it with a power floor scrubber using a white 20 inch scotch pad laced with diamond bits. The one pic where it looks like I am finally cutting through the white topping is a result of 10 - 12 passes. At this rate it will take me a good 40 hours to get this stuff off. I guess eventually, I will end up with nice shiny floors. I wrote to customer support this evening to see if they have any solutions for taking this stuff off. It is very hard. I suspect I did not "rinse" it thoroughly enough, leaving this residue.

Even then, the floor scrubber doesn't go right up to the edge of the floor; so that will have to be done by hand somehow. I have a Bosch concrete grinder, and am looking for an adapter so that I can mount a scotch pad. Anyone aware of such an adapter for a Bosch CSG15, five inch concrete grinder?
