Every so often you hear about some new wonder material that sounds too good to be true-and that's usually because it isn't true. Recently there has been a lot of talk about a miraculous new concrete floor coating and sealer called polyaspartic polyurea. This material, according to its proponents, can be applied at nearly any temperature, bonds easily to nearly any concrete surface, cures to full strength within half an hour, is flexible enough to bridge small cracks, can withstand high temperatures when cured, and has superior stain and UV resistance.

So, you're asking, is all that really true? After talking to lots of people, both believers and skeptics, I believe that the simple answer is, yes, it is true-BUT. The big "but" is that you must properly prepare the floor and the moisture vapor emission rate can't be too high and you need to have the proper solids content in the polyaspartic coating to allow it to wet out the concrete surface in order to develop proper bond. When those conditions are met, polyaspartic floors are extremely successful and an experienced contractor can indeed complete a floor in a single day. But-another but-when moisture-vapor emission rates are too high and when using 100% polyaspartic coatings, some floors have failed. Here, we'll give you both sides of the story and discuss the applications for polyaspartics, ranging from a new way to topcoat decorative concrete floors to sealing concrete countertops.
