Concrete Basement Floor Prep
First post here. I've been reading posts for a little while, and have found some great advice so thanks to the forum. I tried to find an answer for this particular question (actually a few, so I'll probably be posting more questions) by searching, but had little luck so here goes.
I bought my house in February 2008. It was a vacant house (older woman had moved away and left the realtor in charge) that had a minor flood when a water pipe burst between the first and second floors. It was discovered quickly, and a flood abatement team was hired to remove the damaged flooring and dry the house out. So, I bought the house as is for a pretty steep reduction in price. It's been a work in progress ever since.
I'm currently trying to set the basement up as a game area (poker and ping pong mostly) and gym space. Nothing fancy, really. I'm not in a position to finish the basement, so I'm just trying to make it hospitable. Anyway, the basement was originally partially "finished" with some kind of glued flooring and a drop ceiling on one half, and the other half was used as a workshop for art projects and framing projects.
I removed the wall to rejoin to the two halves and want to either paint the concrete floor, or put down a product like Rustoleum's EPOXY SHIELD.
So first I need to clean the floor. The questions I have:
1) There is what appears to be some adhesive residue on one side of the basement from either glued carpet or linoleum. It's not really raised, but it's noticeable. Do I need to remove this before I point/epoxy the floor? If so, how?
2) The side of the basement used as a workshop has stains from, well, stain. I believe the original owner used this half of the basement to stain frames he used for his artwork. Pretty much the same question as above. Should I / How do I remove the stains from the stain?
I've attached pictures that I hope help demonstrate what I'm talking about. Thanks in advance!
