Epoxy Garage Floor - Epoxy Vs Polyurea, Adhesion

 There are two competing products in the garage floor coating industry: the venerated applied epoxy/polyurethane coatings, and the relatively newer polyurea coatings. First, the coatings are chemically connected; they pension a common chemistry.


Both coatings have remarkable adhesion properties, and are deeply durable, at least compared to typical paint products. Another introductory narrowing is that although advertised as "polyureas", garage floor polyurea products are in intend of fact hybrids. A unadulterated polyurea cures in 15 seconds or in view of that--obviously not every share of easy to apply unless it is sprayed. Pure polyureas are sprayed, and used in industrial applications.


Strenghth and Adhesion


Adhesion is important because garage floors endorse on a beating. If the adhesion in the middle of coating and paste floor fails, in addition to the project fails. Both polyureas and epoxies adhere tenaciously to the surfaces to which they are applied-but by yourself once the underlying surface is prepared skillfully. Do you know about polyurethane?


The hardship past polyureas is that the condensed airing time may not abundantly "damp" the authentic surface to which it is applied. This wetting of a surface means absorption, which means adhesion. We know that Premier Garage uses some form of hybrid, and the recent suit brought by some of its franchisees on the go, as one of its claims, allegations that PremierGarage's hybrid products nonexistence adhesion.


It's unaided an allegation even though, and I would suspect that the disquiet may lie in the surface preparation, rather than the coating properties. Here in Austin, the one Premier Garage installation I observed was prepared following an acid conclusive, and not later a visceral grinder. That's a recipe for disaster--the best preparation is always surface grinding.


All in all, polyurea hybrids and epoxy coatings, following applied in imitation of more accurately-prepared surfaces, have more than adequate adhesion properties to adhere to even imperfect concrete for at least a decade.
