Concrete prep questions

[cwrandolph]

I started working on my garage floor last fall. It had an old epoxy coating which was more difficult to remove than I expected. Ended up using a Diamabrush tool on a 9" grinder. I got about 2/3 of the floor stripped before cold weather set in and I am finishing it up now. My question is about how to clean the concrete before the new coating. I am planning to use the pigmented NOHR-S polyurea kit which includes a primer. Is a good scrubbing with a degreaser OK or do I need to do and acid etch? Or pressure wash? We have been parking on some of the area that I stripped in the fall but there hasn't been any oil, etc. on the floor (just salt water dripping off the cars). Any advice is appreciated.

Acid etching is redundant and not necessary due to the grinding. Since you have been driving on the concrete, just clean it well with TSP or a degreaser. Make sure you allow it to dry real well and then you are ready to go.
