Down in this basement I can see 2 layers of gray floor paint were it's

Would the water absorbed into the concrete have done any damage to how
well the bottom coat sticks to the concrete? I'm guessing if it was
done right the first time it should be ok?

Now if we want to repaint the floor again, what kind of prep work should
be done? I know any loose or peeling paint should be removed, but how
do people do this on a large scale. Is there any kind of equipment to
rent? I thought of a sander for wood floors but imagine it would get
clogged up with paint fast?

The bottom line is we want to paint it and do as good a job as we can.
Possibly garage floor 2 part epoxy paint... if that can go over the old
paint, I haven't checked the labels yet.

Idea's?

Sandblast entire floor. A messy but necessary first step. The water
has now absorbed int the concrete dont paint anytime soon

But floor paint never lasts. Why not tile floor.

And whats the source of the flood, before you try to make things look
better add a interior french drain if you can

We had lots of rain and they thought the giant sump pump failed but it
was flooded from a 4" busted pipe on the boiler, I suppose it rusted bad
enough to just let loose. They replaced the pipe, pumped out the
basement and a professional clean up crew was there with fans, heaters,
and dehumidifiers. Three days later another pipe let loose! The clean
up crew had damage to a lot of their equipment. Supposedly the plumber
looked around and replaced a few pipes the second time. After the first
pipe burst they had the water meter read, about 40,000 gallons.
Hopefully the insurance will pay for a new sump pump. The thing was
noisy as all hell, it needed bearings (no grease fittings). Sounded
like a diesel engine but louder. I think it's 5HP (real 5HP). It must
have bit the dust during the first flood.
