Concrete surfaces that have been etched will look rougher than those with a more refined texture. It should be similar to 100 grit sandpaper and should be dripped in water. You can check to see if the texture is sufficient. In a matter of minutes, you can create a dark profile by dripping water onto the floor. Single-coat epoxy kits often come with etch and clean solutions, but they aren't strong enough for the desired surface profile.

A concrete surface that's been etched will look more rough than one that is smoother. It should look something like 100 grit, and be dripped with water. If it doesn't look right, you can check that it's texture enough. The floor will turn dark in minutes if you pour water onto it. Some single-coat epoxy kit kits include clean and etch options that aren’t strong enough.
