Thanks to everyone for all your support. I spent almost 17 hours this weekend grinding on about 120 square feet. As I mentioned, the concrete was extremely hard, at least on the top where the concrete guys power troweled it within an inch of its life. Even the soft bond tooling just stopped...

Thanks for all the replies. I went to the rental place and swapped the 30/40 grit dyma-dot for an 18 grit dyma-seg. It started cutting great but just like the other one, after 10 minutes it was just polishing the concrete. I took Mikes advice to tilt the grinder and it started digging in better...

Mike, thanks for the reply. The reason I thought they might be glazing is that when I first started, you check the grinder for level by letting it run in a spot for a few seconds to see if it grinds a complete circle. That removed all the top surface and left a groove I could easily feel. Now if...

Mike, Thanks for the replies. I do have dedicated 20 amp circuits near the concrete. I know the scarifier will be quicker but no one in town rents one one that is electric. They just carry the gas ones. Not great for indoors. Thing is, I don't have to take down much area that is 1/2" The...

Mike, The graph is better than before after the grinding I had done already :) Yes it will be the 110v Edco non-turbo grinder. I will have it for the whole weekend so I do have time. I asked the guy who did some hand grinding already and and he said the concrete was very hard. He started with...

I originally started this discussion over on the old thefloorpro forum but the forum shut down. Hopefully I can resurrect it here. Thanks in advance for any help. I am finishing my basement and have about 550 feet of area I want to use tile or maybe LVP, both of which would be professionally...
