Cob: Re: earth floors

[Matthew HALL(SED)]

Dear all,

Thanks for all the feedback and ensuing discussion, but has anybody actually TRIED adding PVA
adhesive to mud renders etc. I have made experimental adobe blocks with diluted PVA water repellent
surfaces and they behaved as normal but were 100% waterproof - it just beads right off! Has anyone
tried this in the field?
