you can do the same with lime and shredded paper, as in the Chineses recipe I refer to. soaking for a 2 WEEK period with just enough water, breaks down the paper, and a quick rototilling mix may do a similar job.. you get a cottage cheese type plaster that can be altered significantly with sand.. gritty Mexican style wall plaster or less sand makes and old work softer plaster. try it too. here is the recipe again. Chinese recipe for Paper Lime plaster [interior use]A By WEIGHT-1 part (lb.) chopped/shredded paper-office paper – or newspaper insulation to 10 parts (lb.) soft lime putty (type N or S hydrated lime soaked in water 48 hours) Mix well in large bucket or bin with tight lid. Seal lid. Let mellow 2-4 weeks, stir in 1/2-1 parts sharp sand to make more trowelable. Mix with paint stem/paddle blade to make creamy.. Spread on wall by hand or trowel. Sculpt and dry. feather edges thin at stop points. Can be limewashed; embed tiles while soft. Adding extra sand gives a stronger, more old world plaster/mortar look; for outdoor use eliminate paper or coat with sealer, or waterglass. Note from Charmaine: Successfully applied to new and old DRYWALL, particle board on my work studio & bathroom walls. AND used outside in weather as an external plaster!! still sticking and staying in place, with a thin layer of waterglas applied one time, 2 years ago.

I have mixed cob with a rototiller and I have mixed earth floor material with a rototiller, but never plaster. This week I did a very small scale test on plaster which I think could be ramped up to large scale production. I started by putting a bundle of news papers in a soaking pit and after two days removed the papers and tore them into strips. (The soaked paper tears very easily.) I then put it in a mixing pit and turned it for a bit with fire clay ($12. per 50 pound bag from places that sell brick laying supplies.) The result is a light clay insulating material with a little clay and a hard plaster with more clay. The light material could be molded and dried into blocks to fill cavities for insulation and the hard material makes a fairly decent wall plaster for covering a lath. You can, of course, substitute screened clay for the fire clay. I usually dry clay, break it up with a tamper in my concrete slab and pour the powder through a screen. If anyone has a project where insulating blocks might come in handy it would be nice to see someone else experimenting with this and other new materials.
