Peeling epoxy – floor coating failures

Underground parking lots cover huge areas of thousands of square meters and even tens of thousands of square meters for a single parking lot in malls and commercial centers.  Smaller areas for industrial plants and storage halls. All these floors are concrete floors that undergo  a  beautiful glossy epoxy coating in a variety of shades and markings. Lack of skill and/or disdain for the instructions for preparing the surface are a main cause of failure manifested in peeling, lifting and cracking of the coating which will have to be peeled off and coated again.

Epoxy coating with a suitable thickness for driving vehicles for long-term durability should be about 3 mm, but due to the huge areas in the shopping malls, the laborers are satisfied, due to the price, with a thin layer of 0.5 mm. A thin layer and sensitive to mechanical damage. In factories and warehouses the problem is smaller, they can afford a thicker coating which is of course stronger and will withstand wear and tear for many years. Durability for many years is more important for them, since a repair involves shutting down its activity, a high financial loss, while in parking lots, parts can be shut down for repair without shutting down the entire parking lot.
