Earlier this year I installed 12 mm laminate flooring throughout my house, and it looks pretty good if I don't mind saying. Problem is now that the weather has warmed up, and flooring seems to have shrunk a bit, and now the boards squeak when I walk on them. When the weather cooled off a while ago, and boards expanded a bit and the squeak was gone. So, how do I, or is there, a fix for this problem? Ant suggestions would be great.
