Epoxy garage flooring

New construction, putting in an epoxy floor. Anyone know anything about polyurea? Regular epoxy flooring is supposed to be put on at something like 60F or above. This will go on in December in Wi. Even though it’s a heated garage guys we’re concerned about temps along the edges. One guy, been in business for 20 years said he would do it. The polyurea can be put on at -30F. Pros and cons to each. Anyone have the polyurea?
