Default Painting a concrete floor that's been power floated (etching?)

My workshop floor has been power floated and I believe I need to etch
the surface before painting. Is this just a case of wetting it, brushing
on some hydrochloric acid, and then hosing it out after about 20 minutes?
How can I estimate the amount of acid for 30 m2 floor area?
How do I know when it's sufficiently etched?

No takers?
