Re: floating floor doorways
Most of the snap fit floorings say that you can use a knock block to drive the tongue and groove together. I would recommend you do this with two scraps that are the width of the door, not only for practice, but to see if you can indeed knock them together.
Another method would be to stop the flooring on the hallway side, ending with a T-molding, restart laying the floor from inside the room. It will be a bit of a pain, but you can pop the casing (door trim ) off on the hallway side so that you get the flooring all the way to the wall.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
