In this case, the latex paint is acting as a bonding agent. Others
have I believe used hydrated lime plasters (Charmaine?), someone long
ago used ground up wall board (gypsum plaster). Others use a variety
of additives which might have a bonding agent effect, such as prickly
pear juice or various pozzolans via clay or other kaolin derivatives.

I think in the end it just comes down to testing it out and making
sure that whatever you use meets your particular bonding needs. There
are many roads here, all leading in the same direction.
