Should I let the main bulk of the cob mass dry before I put a finish coat of earth plaster on, or just go for it? The bulk of my cob around the ducting is straw free, so I figured I'd give the whole thing a coat of cob with straw in, as a base for my plaster finish. Sound like a plan?
Steve : More important is the rough texture of the newt to last layer to give the two layers a good binding surface. Some people use a squeeze or pumpspray bottle to wet down the old layer to get a good bond between layers, any dirt becomes part of the Cob. Some like to paint on a layer of thinnish Clay slip between
every cob layer ! Whatever seems to be a better use of your time, right now ! pictures, yours isa good build we want more pictures ! Big AL
