These are the new kids on the block. Well, they have been around for a while now, but they have not been superseded yet. These have made a lot of careers in the garage coating industry. They have also made it easier on the homeowner. No longer do you have your garage torn up for a week. Now in one single day you can have a finished floor that you can walk on in a couple of hours (vehicles should wait 24). These out test the epoxies and urethanes in the lab. They are self-priming, can be recoated in an hour or so, have great sheen and lay down nicely. You can achieve most decorative finishes with them and they can be used on the exterior.
It is nice to have this fast recoat time, but if you miss it these products will not bond to each other. So, we coaters need to pay attention to this. They also self-prime, but not like an epoxy. They do not attach like the epoxies, but have had great success. Your turn around time is incredible and your finished product is just as nice. These products do stink in the lower solids versions. Thought tests show they outperform urethanes some still feel that the urethanes out do the Polyaspartics.
