If you can get good ventilation down there, the best way to go is two part
epoxy paint. But ventilation is very important.

Working on revovating my Mother's basement. We pulled up rubber backed
carpet that had been down at least 40 years. This left a lot of rubber
carpet backing and glue stuck to the concrete. Scraped and scrubbed until
the floor looks and feels like clean concrete but it is still stained
black by what was there before. I had wanted to use a stain on the floor
but I'm now thinking I'll have to paint it. So the question... do I need
to use some kind of primer on the floor to seal the black stain so it
doesn't bleed up through the paint...and if so, what kind of primer?
