I recently pulled off the carpet that was glued to the cement around my pool
in the back. I'm not sure how long it was there (I just bought the house
last summer) but it was disgusting in some spots (looked like black mold)
and had moss around some corners.
My gf and I decided that it would be stupid to put carpet down again for
several reasons. We've decided instead to paint the cement around with an
off white colour. However, some of the glue from the carpet remains in many
spots on the cement. Is there any type of "grinder" that can be rented to
clean up the cements?
A friend of mine mentioned that it is against the law to finish external
cement smoothly, it needs to be rough. Although it doesn't look like a
basement floor, the cement is pretty smooth. Is there a tool that will make
it a bit rougher during sanding?
Lastly, are there special paints for cement, or will any oil based external
