There are many differences and similarities between polyaspartics and epoxy coatings. In many cases, once the product is installed you cannot tell the difference. We’ve outlined below why you might choose polyaspartic polyurea over epoxy and vice versa.
Polyaspartics are thinner and more abrasion resistant than traditional epoxy coatings. A major benefit to them is the fact that they are 100% UV stable, meaning they will not turn yellow due to exposure of the sun or artificial UV lighting.
A major benefit to using a polyaspartic coating is that the installer is able to apply multiple coats and sometimes complete a several coat installation in one day. The reason for this is because polyaspartics cure using available moisture in the surface and in the air.
For floors that have a heavy texture that needs to be hidden, polyaspartics can still be a solution but they will require either multiple layers or decorative colour flakes to hide the texture. This is due to their thinner nature and also the fact that polyaspartic polyurea cures too quickly to be an efficient self-levelling coating.
The vast majority of residential garage floors do not exhibit any of the variables that would prevent the use of polyaspartic coatings. In some cases however, epoxy coatings might be a better solution.
Epoxies used in the coatings industry, are typically thicker, and have levelling properties not available with polyaspartic polyurea. The benefit here is that less coats are required in order to achieve a smooth floor when one is desired.
An example of an environment when a 100% solids 2-part epoxy might be chosen over a 2-component polyaspartic polyurea is when a large square footage job is comprised of multiple small rooms and hallways. This is because epoxies, while they take longer to cure, allow for more intricate work to be done without fear of the material curing during the installation.
Epoxies also make excellent repair mortars and bases for polyaspartic polyurea floors, this is to say that in some cases both epoxy and polyaspartic polyurea may be used for the perfect coating solution. Unfortunately today, there are many sources across the internet stating that one type of coating is better than another for all circumstances; this simply is not the case. As we have mentioned above, both types of coatings have ample benefits.
