Place a 2 in (5.1 cm) plastic washer over a 5/8-inch (15.87 mm) drywall screw for each hole you drilled. If you use lime putty from the start, mix up the set coat with play sand, or kiln dried sand 50/50. Screw the plaster into the lath below and let the glue dry. just leave the seconds slightly back from the finished edge. Step by step, Rory walks through the repair process, from g. then put the seconds on once it's dried (leave it a week or so if your using a lime putty mix (less for NHL or a backing plaster). Bringing back this old house James Koorey shows you how to restore beautiful, original plaster. Now you can simply use either the backing plaster, or sharp sand and putty to put the firsts/scratch coat on.when you scratch it, do it at 45 degrees to the lathes, otherwise you might end up cutting through and loosing the keys on the back. Once the edge of the hole is sound, clean up the laths, brush then over to get rid of the dust, then damp them down with water. then you can put a little PVA round the side of the holes ready to fill with either a backing plaster, or some sharp sand and lime putty. Use a sharp stanley knife to smooth off the edges of the holes you counterbored. use a spade/flat bit around the eges, and make some counterbores in line with the laths, then use stainless screws, and some large flat washers to screw back the existing plaster to the laths and give it back some strength. If the rest of the wall is still quite sound, and not falling off (if it's a little loose you can still get away with it).
