New Floor laid ... what have I done wrong ?

[ABN]

Hi agaib.

As some of you know I in the proccess of laying new pine floorboards.

Have finally finished one room and part of the hall. Took the advice given in the forum and used a porta nailer rather than screwing as origionly intended. Was nice and easy to use and quick to ... perhaps tooo quick.

Problem I have is that in numerous places the boards pop/crack when you walk on them which is a little upsettng.

So 2 questions
1) What did I do wrong? (need to know this before progressing to the other rooms so it don't happen again.
2) What can I do to stop the poping/cracking apart from nailing from the top of the board which I would rather not do.

Leave it for a week or two: wood has to settle in place and adjust (yes, again) to the normal circumstances in the room.
This is very normal, our flooring in our house still can creak sometimes in the morning when we walk on it for the first time that day. The lower temperature during the night 'unsettles' the floor a bit, nothing to worry about (at the moment, come back here if it still goes on, or increases in two weeks time)
