Wolverine manufactures these type of coatings, but not for garage use, only commercial use due partially to patent issues. However even with our commercial contractors they're not popular. Our epoxies and polyurethanes (BondTite 1101, LiquaTile 1184 and EnduraShield 2254) out perform them in all areas except one - return to service. If a customer must get their floor back into production ASAP, then these fit the bill. Aside from that there are better options.
Additionally as mentioned before, these can be very tricky to apply, and if things do go wrong they can go very, very, wrong. I'd say they're strictly for pro applications.
