old expanded metal lath for plaster?
I ASSumed that my house had gypsum lath, but after (finally) fixing the ceiling in my kitchen I now realize that most of the house is metal lath and the gypsum that I saw previously was a spot repair.
The reason that I ask is, in several rooms I have cracks in the ceiling running the length of the room, quite evenly spaced, and perpendicular to the direction of the joists above. My suspicion is that it is the "joints" between sections of metal lath. I also am inclined to "fix" said cracks by shooting drywall screws into the joists on either side of said cracks, then using mesh tape and drywall mud to conceal. Sound reasonable? Should I use washers to help support screws? If so, how to countersink? Buy a Forstner bit and treat it as disposable?
