[Cob] Coblist Digest, Vol 15, Issue 29

[Kindra Welch]

I have had similar experiences with straight lime wash and therefore start with a milk paint base to make the wash.  It has worked for me to order a gallon of "milk paint base" (anti foaming agent is nice too) and mix with lime putty and water to make 3 gallons of lime wash.

I have also experimented with making my own casein from milk and/or using casein powder - both were fun experiments but clearly required more research and/or chemistry background than I had to offer ;)
