In this video we explore all types of problems that we can get with epoxy floors!
I have gathered what I consider to be the main reasons why epoxy floors can fail:

1. Poor surface preparation – A surface needs to be properly prepared in order for it be able to bond mechanically with epoxy coating. This means it should be clean, dry, dust-free, and the surface must be ground or shot-blasted before applying the primer.

2. Humidity – Epoxy doesn’t bond well with humidity. Therefore make sure that the surface is completely dry, that there are no pipes dripping and most importantly that there is no rising humidity from beneath the ground.

3. Weak substrate – What ends up happening is that you don’t actually have the epoxy detaching from the cement, but the cement detaching itself from the cement.

4. No (or wrong) primer – Always use primer for industrial floors! Floors experience heavy wear and tear don’t assume the resin will simply just stick to the substrate.

5. Incompatible substrate – Make sure the substrate is compatible for epoxies both in terms of adhesion as well as tensile strength. For example wood is far more flexible than epoxies which leads to the epoxy cracking simply because it cannot follow the expansions of the wood floor.

6. Contaminated floors. This problems comes up in old installations (food and drinks factories, car service shops) that want to install an epoxy coating over the old floor. All oils, greases, residues must be properly cleaned before attempting any type of fresh coating. Don’t expect proper bonding otherwise.

There is also a 7th reason. Make sure that you watch the video to find out!
