How does epoxy paint work?

Applying a paint like this to any surface is usually best performed by an expert, as it can sometimes bubble and run, but it is cheap, usually fume-less, and unlikely to peel, so if you feel that you can give this project a go, then it is something that is well worth doing yourself. Getting this job done doesn’t need the assistance of a professional if you have some basic home improvement skills. All you have to do is follow a few simple guidelines to get the work done quickly and easily.

POLYUREA AND POLYASPARTIC GARAGE FLOOR COATINGS

One garage flooring option that has created quite a buzz in the industry the last few years is polyurea/polyaspartic floor coatings. This relatively new coating has become the latest favorite for installers as an alternative to epoxy. It has created some confusion for home owners as well. The fast curing ability of this system is being billed as the “Holy Grail” of floor coatings and is advertised as the best of everything that a coating can do.

So if it’s not an epoxy, what is it exactly and why would you want it on your garage floor? Let’s unravel the confusion about polyurea and polyaspartic floor coatings and see why many garage flooring companies are pushing this new product.

WHAT ARE POLYUREA AND POLYASPARTIC COATINGS?

Without getting too technical, Polyurea is a subgroup of polyurethane. It is formed when isocyanates react with water or polyetheramines to create a urea linkage. Like epoxy, it is a 2-part component that mixes resin with a catalyst to cause the curing reaction that makes the material hard.

It has low to no VOC’s and has an elongation rate that exceeds 300%, making it much more flexible than epoxy. It is commonly used for spray-on bed liners, interior pipe coating, liquid containment lining and many other industrial applications such as tunnel coatings and fillers for joints. Because of its extremely fast cure rate (less than 5 seconds and fully hard in less than 5 minutes), most polyureas require specialized equipment for application. Polyaspartic is a type of aliphatic polyurea.
