I'm getting ready to lay a laminate floor in my basement. The floor is
smooth enough, except for two places.

In one place, there was a 2'x4' when the floor was poured. This created a
raised area and a lip, as well as a depression where the 2'x4' was. I have
no problem filling the depression, but I can't figure out how to remove the
"hump" around it. I've tried a chisel and large hammer with little results.


How large a hammer? Get a BFH !
These work fine near the edge of concrete
