Where We Specify It
It goes on as the clear wear layer over almost every flake floor we install, whatever the base coat underneath is. As a full build it makes sense on any floor that gets daylight, so open garages, sunrooms, enclosed porches and shops with roll-up doors. It is also what we reach for on winter work, where an epoxy build would depend on weather nobody can promise, and on jobs where downtime is the expensive part and a shop cannot be closed for a week.
What It Costs Against Epoxy
More per square foot. Across Ontario polyaspartic runs roughly $6 to $12 installed against roughly $5 to $9 for epoxy, and what you are buying with the difference is speed, cold tolerance and UV stability.
That is not always worth paying for. On a heated basement that never sees daylight, epoxy does the same job for less money. On a garage with the door open half the year, the polyaspartic is the one still looking right in five years.
The Trade-Off Worth Knowing
Polyaspartic gives a much shorter working window. It is already curing while it is being applied, which means it wants people who have laid a lot of it and a clear plan for the room before anyone opens a tin. That is a good reason to be careful who lays it. It is not a reason to avoid it.
