Polyaspartics represent an exciting advance in the world of concrete floor coatings, being capable of providing a top layer that is hard, durable, and incredibly nonreactive. Yet many people shy away from embracing polyaspartic coatings simply because they do not understand enough about how they are applied. If you would like to improve your knowledge of the polyaspartic installation process, read on. This article will present a useful, step-by-step overview.
It is important that the concrete floor be in the best possible state to receive the polyaspartic coating, otherwise it may not penetrate or adhere as designed. It is especially to eliminate so-called laitance. This term refers to the natural accumulation of a film of whitish particles on the surface of the concrete. Laitance is best removed through surface grinding using a special diamond grinder. Acid etching should be avoided, since it will increase the concrete's moisture content and potentially lead to further problems.
Crack And Joint Repair
Next it is important to attend to any nagging cracks or especially deep joints. The goal here is to ensure a completely level surface. This can be done by using sand to fill the cracks, and then applying just enough polyurea to wet the sand. The polyurea will cure within minutes, resulting in a patch more than solid enough to receive polyaspartic.
At this point, the floor has been appropriately prepped for the polyaspartic to be applied. First, the two components of the polyaspartic--resin and catalyst--must be mixed together. Once this is done, there is a fixed installation window, after which the polyaspartic will no longer be capable of being spread. Fresh polyaspartic is applied by means of a roller brush. In most cases, a minimum of two coats are applied, with the first coat acting as a sort of primer. Usually around an hour is allowed between coats for the polyaspartic to cure properly.
If the polyaspartic coating is meant to stand alone, then at this point the process is basically done. However, many people choose to incorporate decorative elements--whether vinyl chips, color pigments, or even sand. In such cases, three coats are usually used. The second coat, known as the "bed" layer, is where such elements are incorporated. After they have been put into place, the bed layer is allowed to cure. Then a protective top layer is applied and allowed to cure, at which point the installation process is complete.
