[papercreters] Re: Compressed Blocks

-
Hi Ernie,what about adding a bonding agent to the stucco mix? Like
drywall which in essance is plaster of paris it can also replace the
portland cement powder,i have read this on living in paper or the
press can have small groves when its pushed out.I dont see a problem
with it sticking because of its molecular structure they are both the
same product.
As far as latex paint in the mix we have done this with ceiling
texture in large hotels to keep people from jumping up and draging
there hands accross the ceiling and knocking it off,it actualy will
make your fingers bleed. Clair.
