There are two competing solutions in the garage floor coating industry: the classic utilized epoxy/polyurethane coatings, and the somewhat newer polyurea coatings. 1st, the coatings are chemically connected they share a widespread chemistry.
The two coatings have impressive adhesion qualities, and are incredibly tough, at minimum in contrast to common paint products. Another introductory issue is that while advertised as "polyureas", garage floor polyurea products are actually hybrids. A pure polyurea cures in fifteen seconds or so--clearly not incredibly straightforward to utilize unless it is sprayed. Pure polyureas are sprayed, and utilised in industrial purposes.
Strenghth and Adhesion
Adhesion is crucial for the reason that garage flooring get a beating. If the adhesion amongst coating and cement ground fails, then the challenge fails. Both of those polyureas and epoxies adhere tenaciously to the surfaces to which they are used-but only when the underlying surface area is organized effectively.
The issue with polyureas is that the minimized drying time might not adequately "soaked" the concrete surface area to which it is utilized. This wetting of a surface suggests absorption, which indicates adhesion. We know that Premier Garage uses some type of hybrid, and the the latest lawsuit introduced by some of its franchisees associated, as just one of its claims, allegations that PremierGarage's hybrid products and solutions absence adhesion.
It's only an allegation even though, and I would suspect that the challenge may perhaps lie in the floor preparation, rather than the coating homes. In this article in Austin, the one Premier Garage installation I noticed was well prepared with an acid option, and not with a bodily grinder. Which is a recipe for catastrophe--the very best preparing is constantly area grinding.
All in all, polyurea hybrids and epoxy coatings, when utilized about effectively-geared up surfaces, have additional than satisfactory adhesion houses to adhere to even imperfect concrete for at minimum a 10 years.
