Just thought I'd share my experience of painting my new shop floor as it could help someone else. My shop is 20x35 with smooth concrete floor. I wanted something other than bare concrete. Decided to just paint it with Sherwin Williams Tread Plex after considering many other options. Took the advise of everyone that said the floor had to be etched first and decided to use a concrete grinder rather than acid. The grinding went very well, didn't even need to buy a set of diamond pads as the ones on the machine were hardly used.
Here's the lesson learned. When you grind you use just enough water to keep the dust down and help with the grinding. This creates a concrete slurry over the entire surface. If you let that slurry dry you will spend hours scaping it up, big mistake. Be sure and get it off while it's wet.
Anyway, I decided to give the floor a cammo look to make it a little out of the ordinary and help hide the dirt a little. I think it turned out OK and a side effect is the texture makes it less slippery.
