@greenbeast I called 2 companies for estimates $4900 & $5800 for 950sq ft. Whether it’s old concrete or new…they say it has to be ground. It allows excellent adhesion to the surface. Since I get tired easily these days I rented the 10” concrete grinder from Home Depot for $187 for the day. It was a lot harder than steering and old FJ40. Using the generator for power, the job was done in under 2 hours. The dust was incredible but using a blower and respirator I cleaned out the area. Took 4 tries to insure a semi dust free floor.
I used (2) MPC-100 in 3 gallon pails from Amazon For the 1st coat and 2 for the second. Every review of every product the users complain about the area coverage and running short. It is a 2 part epoxy and added MICAH powder for color. Basically gray. Spread it with the squeegee and followed up with the roller to smooth it out and then cast the grey/white/dark grey flakes( this takes a bit of concentration to ensure uniformity) I could have done better in some spots . I might have needed another 15-20 lbs of flake for the density I wanted. If you throw them up in the air , they scatter and flicker to the ground like butterflies compared to tossing them as a handful.
I let it sit over night. It is 9:45 Saturday am and I have been finished with the second coat for almost an hour. All that’s left is to let it harden a few days.
the squeegee is more work than the roller. I have about $1200 all told with materials, rental, spreaders, rollers. My quotes were almost $6.00 a sqft and we have labor and materials for $1.20
the hardest part is broadcasting the flake as this is really the look you get. It sits under a clear coat surface so a thick patch shows up well compared to a thinner area. I would absolutely do it again. I am 69 with arthritis issues and a-fib and both of these days started at 79 degrees and it was near 92 on Friday when we finished. Right now at 9;50am it is 81 with 85% humidity… bring 2 shirts!!
that is the complete story

. I have only seen the 1st dry coat, looks good, seems hard. If it all winds up as it seem it will, I’d be very very pleased. Before adding the second clear coat, I ran over the entire surface with a steel scraper to kill any peaks of flake ….scraped up a coffee can of excess
