After more searching, I found that Maipei's website says:
"Concrete surfaces must be mechanically profiled and
prepared by shotblasting, sandblasting, water-jetting,
scarifying, diamond-grinding or other engineeredapproved
methods (reference ICRI CSP 3 standards for
acceptable profile height)."
Which I really can't do--it's a 5' by 5' space in an occupied house--I
can't do anything that's going to generate that much dust, to say
nothing of removing the shot or sand, or dragging a sandblaster over my
wife's carpet.
Ugh. This has all the makings of going bad fast.

They've got standards on surface roughness ("concrete surface
profile"). Higher the number the rougher the surface. I know
grinding typically results in CSP 2, but I don't know what the others
look like.
Can you ask your supplier or manufacturer about it?
