yes mine is floating and the floors were not level. The cracking sound is just in these areas - i'll try the talc. what should I buy? Is it regular scented talc for bathroom use?
Johnsons baby powder bottle thingy ??? should do the trick. Don't go mad with it, just a bit over the joins where you hear the cracking and walk on the boards to work it down, although with glue it may never get down into the join but worth a try.
