Before the popcorn ceilings are removed, the floors must be completely covered from wall to wall. To do that, you will need thick plastic sheets that are then going to be taped down at every wall so the floors are entirely covered. Then, you will use contractor paper to add another layer on top of the thick plastic so that there's no chance of slipping while working in the area.
I hope this has helped in your search for your suspended ceilings.
The electrical contractor of today is using products that increase his productivity and maximize the potential profit of his labor. They have a large choice of nail-on products that already have the fasteners attached to the ceiling box and all they have to do is hold it in place and nail or screw it into a joist or truss for it to be secured. Many of these boxes are thermoplastics which are inexpensive and easy to manufacture. They also have the added advantage of not needing to be electrically grounded so this saves the additional labor that metal boxes require.
