Epoxy Garage Ground – Epoxy Vs Polyurea, Adhesion

There are two competing merchandise in the garage flooring coating sector: the standard applied epoxy/polyurethane coatings, and the relatively more recent polyurea coatings. Very first, the coatings are chemically connected they share a frequent chemistry.

Equally coatings have exceptional adhesion houses, and are incredibly long lasting, at the very least when compared to regular paint items. Another introductory position is that while advertised as “polyureas”, garage ground polyurea solutions are seriously hybrids. A pure polyurea cures in fifteen seconds or so–certainly not extremely simple to apply unless of course it is sprayed. Pure polyureas are sprayed, and employed in industrial purposes.

Strenghth and Adhesion

Adhesion is important since garage floors acquire a beating. If the adhesion between coating and cement ground fails, then the job fails. The two polyureas and epoxies adhere tenaciously to the surfaces to which they are utilized-but only when the underlying surface area is well prepared very well.

The trouble with polyureas is that the minimized drying time may perhaps not sufficiently “moist” the concrete area to which it is utilized. This wetting of a area implies absorption, which indicates adhesion. We know that Leading Garage works by using some variety of hybrid, and the latest lawsuit brought by some of its franchisees included, as a single of its claims, allegations that PremierGarage’s hybrid products lack adhesion.

It truly is only an allegation even though, and I would suspect that the problem may possibly lie in the area preparation, somewhat than the coating houses.

In this article in Austin, the just one Leading Garage set up I noticed was organized with an acid remedy, and not with a actual physical grinder. That’s a recipe for catastrophe–the finest planning is normally floor grinding.

All in all, polyurea hybrids and epoxy coatings, when utilized around properly-prepared surfaces, have far more than suitable adhesion houses to adhere to even imperfect concrete for at least a decade.
