SB: FW: Plaster reinforcement

["Wilkinson Kester " <Kester.Wilkinson@lsc.gov.uk>]

catherine, you wrote <<snip>> if anyone had ever considered using fiber
mesh 
reinforcement instead of chicken wire and diamond lath to reinforce the 
plaster....

we lime plastered our house last summer and used a plastic reinforcement
mesh - marketed in england as autex.  Its a plastic mesh with the holes
about 0.75 cms.  We applied it by spraying on a scratch coat of lime
plaster and then bedding the mesh into the scratch coat.  We found that
by doing this we got no cracking over changes in material - straw to
timber etc.  To give a key over the timber prior to the scratch coat we
used reed matting which gave a good mechanical key.  The plasterer who
was advising us first saw the technique used for gypsum and concrete
plasters/renders in germany.  There is a small mention of it in the
edition of the last straw which focussed on plastering.  Given it is
plastic I doubt it has much in the way of environmental credentials but
it certainly worked very well.
