Extend epoxy flake floor under OHD and onto apron?

[Innovate1]

Getting quotes and 2 of the 3 said there is no reliability issue to extend the coating the few inches beyond the OHDs. They all said they often stop the epoxy/flake just inside the door. At least one said just regular sealer on the few inches remaining. The one that said moisture would try to lift the coating near the exposed edge (call them contractor A) said they grind a shallow groove at the stop line to help with adhesion. I had it done to the slab edge on the detached garage and the flakes are starting to come off in that area - done about 5 years ago and the prep was poor but it hasn't had any issues inside. Including a pic of the outside loosing flakes. Keeping the apron dry if weather is rainy seems like a difficult task. All things considered I am thinking of not doing the outside apron.

Contractor A has good reviews but is a one man shop so hard to get into his schedule. He said it would be a week (4 days to prep and coat and 2 days to cure). $6.50 / sq ft plus some adders for expansion joint prep, etc.

Contractor B does mostly industrial floors and can schedule in a couple weeks but is about 40% higher. Surprisingly they just needed a 120V, 20A outlet and the other two needed 240V, 30A for grinder.

Contractor C said they can do it in 2 days as they have a crew. They mentioned some places do it in 1 day with poly color coat that cures faster so they can get the clear coat on the same day but it's not as good. They are a little cheaper than A which isn't really an issue - I want it done right and not have to fight contractors. But C also has better scheduling.

Do you have the space to store all your garage stuff for the week comfortably?

I'd go with the one man gang.

Most professional installers with years of experience do not like to extend coatings past the door. It just asks for trouble with moisture, peeling, and UV damage. A small groove cut in the concrete to terminate the coating at the door is the best practice and a good sign that an installer knows what he is doing.

The most important part you are missing in your info is the type of materials being used, how many coats, partial flake, full flake, etc. Did any of them provide technical data sheets so you could compare performance figures of the materials being used? Assuming the concrete prep and application are on par, it's the materials that will determine cost, how well, and how long you can expect a coating system to last.

That seems like the safest thing. We are getting a pod. Plan is to move everything into the pod (except some tools we may need which can go other places). Then paint and otherwise spruce up the place. Then have the floor done. May have to pay for an extra month of the pod with the 1 man shop due to his schedule. But an extra month is only $180. It will still get done before winter gets too bad.

Just realized I didn't include the pic in the first post so added it.

My floor has a 1" drop right inside the OHD and the coating goes about 3" past the door.

The exposed apron is looking a little sunfaded after about 14 years in South Florida weather.
