I am planning on installing 5/8'' bamboo flooring in my three story
townhouse. I just ripped up the carpet and pad on the second floor and

on the first floor). My guess is that this means I now have a

use concrete cleaner before I can glue?

Patch any bad spots with polypatch material or any concrete patch.
