Cob: Re: earth floors

[SANCO Enterprises, LLC]

Matt,

When dissimilar materials are used and the harder or less pliable is used on
the surface, delaminating usually occurs.  If the PVA were to be used, I
would recommend that the PVA be incorporated with the base material even in
the final topical coating.  Even diluted PVA mixed with the second to last
layer helps make the bond much stronger.
