So a Chicago commodities trader buys a 5000sq ft home in Biltmore Forest NC and she calls me up to remove the popcorn ceilings and finish them to a slick finish. When I show up to look it over I discover the ceilings are drywall hung over the old plaster..the house was built in the 30's.
It was a huge job and I priced it accordingly and started the next day. Myself and two other finishers completed the job in four days. In the process though, after removing the popcorn , we discovered that whoever installed the drywall over the plaster used course thread drywall screws
in as fasteners. Apparently they didnt have screw guns...mind that this is a huge house in an upscale historic district. The builder who renovated the house in the 70's used crown molding as a fix to the mess created in the angles when resurfacing ceilings over plaster and NOT resurfacing the walls. So there was reason this 2 million dollar home had popcorn ceilings.
We coated all the nails after the popcorn removal and with 50% of them the paper turned loose at the point of the hammered impact. "Waffling" is a term we use for this. We spent several hours cutting out the loose paper, renailing(with nails), and taping the areas where the damage was through and through to the plaster.
We didnt use screws because the lath/plaster would spin the heads right off. tough stuff...the structural integrity in building was outstanding in the 30's
story short..the ceilings are beautiful now...and we made good money
I have a technique I use when slicking out aggregated plaster. Making repairs to aggregated walls, you have to use an aggregate in your repair compound or you create slick spots over the repair area. The home owner has asked me to come back and begin a resurfacing of the secondary stairwells. It's a lot of work that needs to be done efficiently. I wont be using drywall...just quick set joint compound and a lot of straight flex.
I want to document this process here w/pics and conversation....It should be interesting.
I should begin this project within the next two weeks.
