What happens here

Once the entire floor has been treated and shows the yellow fizzing reaction, immediately begin flushing the acid off the concrete with a water hose. The water dilutes the acid and washes away the byproducts of the etching process. It's important to continuously flush until no yellow color is visible on the concrete, as this indicates that the acid is no longer active. The water and diluted acid should be directed towards a drain or away from areas where it could damage plants or other concrete surfaces. If the garage does not have a drain, the water will flow out of the garage, requiring careful management to avoid damage outside.

Goal: Neutralize and remove all active acid from the concrete surface.

What they say

Hide

Once you get your acid all sprayed on the concrete floor, I immediately get a water hose and I'm going to start flushing the acid up and diluting it with water towards the front of the garage cuz I don't want it to run out onto this portion of the garage and and actually stain the concrete outside the garage. He happens to have drains inside this garage, so the water actually won't flow out here. If there's no drains in the garage, the water will start to flow out here. So, you want to get it pushed up so you don't see any yellow anymore. If you see it yellow, that means the acid is still active. I keep rinsing till I don't see any more yellow left. I want to see any more active acid. I'm going to walk out to the other part of the garage here. And you don't want to walk under the concrete outside the garage until you rinse off your shoes cuz if you have acid on your shoes, you'll leave footprints across the driveway. I think that's why they cut. And one way is I'll take and to make sure that my floor is rough enough. I just take my shoes and I want to rub on it or take your hand and it should feel about like 100 grit sandpaper. Not not too rough
