The installation instructions for most 3/4" solid nail down flooring states you need 3/4" expansion at the walls. If that is the case how can any boarder be installed without opening up to perhaps 3/4"? Can any corner be mitered? Can you change direction in the flooring without a 3/4" gap". If you go around an island in a kitchen do you need 3/4" on both sides when the flooring is tight all the way around?
We installed a nail down floor that cupped. We didn't leave 3/4" for expansion, there is still room to expand and they say the cupping is due to not enough gap at the walls! Am I nuts or is the manufactures just covering their butts so they don't have to stand behind their product?
