[Strawbale] Possible additive for lime plaster

[Ken Beiser]

I have used fibers in various concrete and stucco projects for about 15 
years.  I first did an interior shop slab (24 by 24) using fibers and no 
rebar or remesh and it has worked well.  I used fibers in Portland cement 
stucco on straw bales and it convinced me to try it in the scratch and brown 
coats on a plywood substrate wall.  It has been about a year and a half 
since I did it and it looks great.  My best stucco job yet.

I get the fibers at the concrete batch plant and it is pretty cheap.  I 
wouldn't do another job without it.  I have never tried it with lime or 
earth plaster but I will.  If the fibers bother you in a slab, you can burn 
them off with a torch of they wear off.  They help the top coat on stucco 
bond with the brown coat, too.
