I just spoke with the builder, and they tell me that it is 2-3'' of
lightweight concrete for noise/fire prevention purposes (the garage is
on the first floor). My guess is that this means I now have a
glue-down job?
The concrete is fairly clean, I have swept and vaccumed. Do I need to
use concrete cleaner before I can glue?
Thanks,
Joe
