I'm sorry to say that the front part of the barn is likely to be 
problematic for you.  You saying this was once a barn is a tip.

On my garage, I used high quality two-part epoxy (from Ben Moore, I 
think) floor paint about ten years ago.  I put it down when the floor 
was fairly fresh - just after the building was completed. On the odd 
occasion when I actually clean it, it looks pretty much the way it was 
when I put it down.  And it's full of british cars, so there are plenty 
of oil leaks.  I did etch it with muriatic acid before painting.  I 
highly recommend two-part epoxy floor finishes on relatively new concrete.

Used the same paint around the same time when helping some folks rehab 
the local municipal animal pound.  We powerwashed and then etched the 
kennels with muriatic acid, and then painted.  The paint wouldn't 
stick.  Research turned up that nothing is going to stick to concrete 
that has been defecated or urinated on.  Never.  Now, I wasn't 
responsible for the project, or chose the paint (epoxy is just standard 
for kennels), so I don't know if they ever found a solution.  Sorry.

But I suspect that the front part of the barn was concrete while there 
were animals in it, and the back part was poured afterwards.  If you 
suspect that may be the case, do some research into re-painting kennels, 
and maybe you'll find a solution.

Right now I'm building a new house and an 8 car garage, and am looking 
into putting down porcelain tile.  A good bit more costy, but not as 
much as you might think.  And porcelain is almost indestructable......

BTW, I did the epoxy job myself - it's not at all difficult, but it does 
take care and surface prep is key.  And even though I left the garage 
doors open while applying, a good quality mask is essential - that stuff 
is rough!

Best of luck!
