[Cob] Re: Leaking Papercrete Roof

[dirtcheapbuilder-Charmaine Taylor]

Asphalt emulsion is TAR..very unprocessed and the lowest on the food 
chain, ...in fact the MSDS  safety sheet reveals  it is non toxic and 
offgassing- outside the temporary smell it has before drying.
AE used to be wasted..it is the left over crude. But you can buy it as 
Henry 107 or Black Jack brand fibered AE in any hardware store.

AE  is tar mixed with water and bentonite clay .in suspension is one of 
the best tricks I know of for lots of small projects to make things 
stick to old wood, dry metal, just about any dry surface.

and, as opposed to some natural builders who rant and dont know what 
they are talking about..it is a non toxic product-- and more friendly 
than any cement.

You  can buy a ROOF formula for coating the roof.... and put a lime 
plaster over it if  you want a different color roof. .  Dn't buy a 
floor/basement AE and use it on the sunny roof area, it will break down 
again.
