I have experience with both ways. A buddy had his shot blasted by a commercial flooring company. It was an old garage that had previously been painted with floor paint. It did an amazing job. The paint was then applied per the directions on the can. It was a Sherwin Williams product and it looks fabulous. I had a garage floor that was in really good shape and tried acid etching. As it turns out, the previous owner had sealed the floor using Thompson's water seal. I went to an equipment rental store and rented a concrete floor sander that has two counter rotating discs on the bottom. It has diamond blocks on the discs. It makes one heck of a mess but it removed the water seal. The results after coating the floor were very good. If I had to do it over again, I would go the shot blast route. It was way less messy and wasn't that much more money than running around town renting tools and buying the diamond blocks.
