What are common and minor epoxy woes?

Peeling Epoxy

It is common for epoxy garage floors to peel off. Why so? The reason is simple. Peeling happens due to a lack of strong adherence. The term for this condition is “smooth surface.” That occurs when the concrete surface lacks grinding.

Flaking or chipping

A little worse than peeling is flaking or chipping. At first, look peeling, and flaking may get used interchangeably. But the difference that you will notice is that when flaking happens, a chunk of concrete layers goes with the coating. 

Aside from weak mechanical bonding, the slab also got a weak substrate. These conditions happened when the floor coating did not undergo proper preparation.

Contaminated floor

Contamination is a minor issue that occurs due to coating without completely grinding or sanding the surface. The epoxy floor coating does not chip or flake, but a spotted surface comes out as the coat cures. Blotches appear on the surface. 

There’s a flake-chip pattern for stylish epoxy flooring, but his contamination is not what you want. The result looks undesirable. So will you fix it?

Bubbling epoxy for not mixing it properly

Another common mistake is when you don’t mix the epoxy properly. The consistency may be too dense or too smooth. The thick coating will not adhere properly to the surface. So curing the epoxy will take time. While it cures, air will get inside the layer, causing bubbles to form.
