There is a section of our epoxy-coated floor that is beginning to fail.

It is located near a drain. My guess is the cleaning chemicals and water have weakened the bond it has to the concrete underneath.

 

Has anyone else experienced this? What have you used to reseal the area?

I tried a 1-part epoxy from Behr designed for exterior concrete, but it is also starting to fail.

 

The rest of the floor is in decent shape, but I have begun suggesting a full, professional replacement.

I would use a 2 part epoxy coating and seal it or use floor paint.  It was some years ago but the plant I worked at had epoxy flooring throughout and we would have to reseal high traffic areas once a year.  We used a 2 part epoxy and then sealed it with a color match paint sealer.  It held up ok we would still have to go back over annually which was a pain point.

nwilson, would you happen to know which brand/style coating you used?

 

I can pick up a Rustoleum 2-part kit from a store near me tomorrow.

I am holding a bit of a grudge against Rustoleum at the moment.

I used their clear coat on a set of car wheels and they came out cloudy. haha I am still not over it

I would be holding a grudge too if it messed my rims up!

Normally comes from a poorly base coat or material being applied on top of the concrete to which the epoxy is then applied to the now completely sealed bottom concrete adhering material - your idea about a full professional replacement is the way to go.

Part of our annual maintenance downtime is patching the floor.  We've used a variety of different ones over the years, and certain high traffic areas look like a quilt with slightly different shades or textures.  Failures near drains and major seams in the underlying concrete aren't unusual.  

 

The professional grade stuff with the really noxious organic solvents will last longer -- but obviously requires some downtime.
