Micro-pitting due to winter salt

[theeld]

I have a 4 month old garage floor, that has just been through its first winter. At the control joints, I would see effloresence accumulate due to the moisture/salt brought in from vehicles. I was somewhat diligent about sweeping the accumulation, and sometimes hosing it off. I recently examined it closely and to my dismay, micro pitting is already present along the control joints. I have ordered some g-floor to cover stalls to prevent further damage.

I am curious if I can solve this myself with a trip to homedepot and renting a floor maintainer/floor sander. I am curious what type of pad I would start with? The pits are very small and surface level at this point, so I am curious if a 'polishing' pad would be enough, or if I would start with a 'grinding' pad? Any recommendations would be welcome.

As a side, I did treat my floor with v-seal which is a densifier about a week after pouring in hopes of preventing some of this sort of thing.

If you could post some pictures it would be very helpful.

You have experienced a "salt etch".
Salt is powerful and although the v-seal likely helped to some degree the concrete is still in touch with salt itself.

Salt wins every time without a topical barrier (epoxy, g-floor, etc....)

I think Scotty is right on... that is exactly what it looks like. You might want to wash the concrete with some Salt-Away before you put down the G-Floor.

Agreed! Also see Shea's post. Taking a little time to clean this floor first is a REALLY good idea.
