The shortcuts that can be taken are in the prep and quality of material. The prep needs to be a mechanical prep via shot blast and/or grinder. Most customers aren't savvy enough to research quality of materials but this is just as important as the prep to determine the longevity and endurance of the floor system. The sealer needs to be polyurethane or polyaspartic (more expensive). Both of these are UV stable. Epoxy sealers are not and will amber in due time with UV exposure. This is how many companies are able to offer a cheaper price and the customer is unaware.
Again, I'm not advocating for work, I'm here to assist anybody that is looking to do this at their home, shop, or business. We do 97% commercial work and about 3% residential small business based off referrals and friends.
I'll be happy to answer any questions anybody may have here or offline. I know some of the companies mentioned and would recommend a few and a there are a couple I saw that I would avoid.
Here's to BTHO Georgia!!!
