Too close to Raleigh, NC | You are probably looking at an epoxy type of coating for either application. But they are extremely expensive and require surgically-clean concrete to get them to stick like they are supposed to (lots of acid-etching and power washing involved). Best bet for the silage pit may be to put down a minimal thickness layer of fresh concrete with fiber in it after cleaning/seal coating/bondcoating the existing slab. For the shop, if it has already got oil/anitfreeze/hydraulic fluid soaked into it, then you will have a hard time getting any coating to stick properly. Concrete is porous and, once something gets in the pores, it is there forever. You can acid etch the concrete to get as good a surface as possible but even then bets are off that anything will stay stuck to it.
The hardest thing we did when we built my brother's shop was stay out of it for a month while the concrete cured so we could seal it before we got anything on it. Would hate to think about having to empty it out now to try to seal the floor.
You could always put in black and white checkerboard VCT tile (I know of one shop that did that - looks real good but then he charges accordingly - but you can do that when you do custom car work on Bentley's, Ferrari's, etc.) | |

Heavy duty concrete coatings?
