These are all two part polymer flooring systems that are both mechanically strong and highly impact resistant. Polyaspartic floors are more costly and come with some advantages. One being that it dries much faster for turn around of 24 hours for vehicular traffic. Polyaspartic floors are also more flexible, chemical resistant, UV stable, and abrasion resistant. Urethanes are very similar to polyaspartics, but not quite as durable or fast curing. We typically like to coat our epoxies with a polyaspartic clear coat. We believe that this combination gives you the best of both worlds, the epoxies give you the most bang for your buck, laying down a thick layer for an affordable price, then topping that off with an extremely tough polyaspartic wear layer.
