Reason 1: Smooth Surface
Inadequate grinding, no mechanical bonding can happen.
Reason 2: Weak Substrate
Weak Substrate can cause a floor to fail. Beneath the epoxy sometimes the quality of the concrete is in bad shape. It can be brittle and loose. Applying epoxy over this type of floor will fail.
Reason 3: Contaminated Floor
If the floor has oils or grease on it, it needs to be properly prepped in order for epoxy to bond. You need to clean the floor and scarifying all the dirt off the floor
Reason 4: Moisture
Moisture can cause a floor to fail. If moisture is present beneath the slab, it will permeate to the surface of the concrete. Because coatings such as epoxy are impermeable and do not breathe, water vapor and moisture can't pass through the coating.
