Repair for Epoxy Flooring

[kbuhagiar]

Hello Folks,

The garage in my 'new to me' home has a sealed/coated floor (approximately 900 square feet). The coating seems pretty thick, and I think it may be epoxy, but I'm not really sure. The floor is in excellent shape, except for a patch where it has peeled up (see picture).

Any repair suggestions? And any way of determining what kind of coating I have?

Thanks in advance.

It looks like there is some sort of white powder on the floor. If that powder is under other parts of the floor, you are going to have a problem with the rest of the floor as well.

There are smart people here who can provide you with specific recommendations.

Before you repair that spot, check the rest of the floor for other areas. Is that spot in a location where oil or hot tires were placed? No sense repairing one spot when another will fail within a short time.

Congratulations on your new to you home.

Congrats on you new home! Based on the thickness of the coating, it looks like epoxy or something similar. It's hard to tell from just a photo. I would suggest contacting the original owner if you can to find out what was used.

Unfortunately, what you have going on with your floor may be a sign of things to come. The white powder is most likely efflorescence which is caused from moisture. When moisture gets trapped under a coating, the white salt residue from efflorescence forms between the concrete and the coating causing it to delaminate.

The key before you do anything is to source the issue of the moisture. Is your slab below grade? If not, do you have sufficient drainage around the slab so that water cannot pool up against it? Do you have a water pipe or drain that runs under that area of the floor?

Shea is right on the money, probably a moisture issue causing problems with the concrete. No way to tell what's down, either patch with standard epoxy and live with it, or recoat the floor. Make sure to clean out the area well, prime, epoxy, topcoat.

Thanks for the replies.

The original owner, and all of his contacts, are out of the picture, so that is not an option. The slab is at grade, no pipes or drains beneath the slab, and drainage is excellent, no issues there. There aren't any other blemishes on the epoxy floor, and this one only came about by way of a careless contractor who dropped, and then dragged, some heavy equipment across the floor.

I will attempt to patch with epoxy. Can anyone recommend an epoxy patching product, preferably something available in a small quantities?

Thanks again.
