hey doug was that with monket pads
No that was with diamonds...4" flexibles.....like I said it was my 1st job, and I didnt know much..like you are suppose to use ridged pads...(funny thing is these flexibles have worked better then any ridged :roll: )
Anyway I did it with a 4" grinder 1st, to see if it made a difference. They had acid washed a different area, but screwed up and walked, put their old pads on, allowed to let the solution run over. Which of course made etch marks. I will find my pictures of it and put them up..
Also Jim, its not sand you would be showing, it would be the aggergate<sp> that would show, and sometime it looks cool "poor mans terrazo" but that is usually 1/4" -1/2" down..(if they did it right :roll: ) Yes sometimes it might be close to the surface but not that i have seen....Also when you are honing/polishing you are not removing all that much surface, i mean it is in the thousands of an inch range...unless you are running 0 grit metals or something.. Thats why I asked about how smooth it is. Sometimes, where to start with the grits is the hardest thing..
Here is a quick break down of how to do the grit levels...David Gelinas told me this....granted he may have switched to other methods by now, but it has worked for me so far.
this is figured on a fairly smooth surface.. with no lipage or adhesive type removal, ALL RESINS
These are WET flooding the floor like stripping, then sucking it up besure to get it all up, so you dont have diamonds from the other lower grits possibly screwing it up.
50
100
220ish grits #s in range differently in the last 2 numbers, so dont panic to make it exact.
densify, keep it wet for about 20-30 minutes, some say add water some dont, read the instructions...
now dry
220 again
400 range
800
1500
3500
My sqft production with a cimex, made for carpet so a 400 rpm range was about 500sqft per hr. I did a 2000 sqft job and it would take about 4 hrs to go over the whole thing which each grit.
Autoscrubbers work really well on this stuff...they help scrub in the densifier and keep it a little wet..they help suck up the slurry and rinse it.
the wet passes are what take off product, the dry passes take very little...and I mean little.
