I am not sure you can get that for personal home use. Its problably expensive. I would love to get my garage floor sealed but I am afraid most of the off the shelf products dont last. I would hate to do all that work to have it peal in 3 years.

This is what's held me up. Seems like everything either has durability issues or is ungodly expensive
