I put down 5g of Hd40 over 1600sq/ft of power troweled concrete. I tried to burnish it last weekend and it didn't go to good. First, renting a high speed polisher was not as easy as I thought, I'm in SE ma and nobody had one. Finally a got one after a bit of a drive, 20" 1500rpm 1.5hp 15A...not a bad machine. I had already bought a box of 3m top line 3100 pads. I have a IR gun so before I started buffing I shot the floor...80F. Started buffing in a small spot and I could only get it up to 90F if I sat there for 10min...so there was no way in hell that was going to work. So I then just screwed around to see how it would polish out...the 3100's just bounced off the hd40. Then I ran down to HD and got some 17" black pads, all they had was synth...I thought they might melt but the didn't. I tried buffing with the black pads and of course they cut better but it was still tough to get the temp up. I ended up just running the black pads over half the garage and then ran the 3100's over that. It came out ok but I still want to do it right plus I need to do the other half.
So the question is what pad grits are you suppose to use to buff this stuff?
And is it too much work for a an electric buffer?? Do I need to find a propane fired one or something that has some weight to it? If I hogged down on that electric one it would blow the breaker ever time.
