I'm pretty sure you are not supposed to leave residual glue on your hands while you push the flooring boards in place. I've spent all day spraying and wiping a very large bamboo floor trying to get the glue fingerprints off the boards. It seemed to be going well until I stood back and looked at an angle to notice that actually it looked just as dirty as when I started a few hours ago. I give up on this one. I've got a lifetime to try to get the marks off now.
On a more positive note, the kitchen arrived yesterday in all her glory. It took all day but she is finally in, minus the bench tops, and I am chuffed to bits.
