For the stick keys are you saying space them 100mm apart so it ends up looking like the stitches scar on my ankle?
I have a mortar mix ready to add...
I think I'll patch after heating the oven fully.
Do you have a recipe for my outer layer?
For the finish plaster Kiko recommends 3-4 parts sand to 1 part lime--is that approx. what you use? No soil or clay? Fiber?
"...I used a hardware modification, reasoning that with wider ends (wing nut/washer) it would give more resistance to pulling apart..."
I'm now about ready for that final plaster. I checked with my local stone and masonry place and they have 1 kind of lime, the type they sell to masons, no other distinction. So what do you suggest for a mix? Also I'd like to make it as weather-resistant as possible; I think I'm more concerned with resistance to rain than having it be breathable, since almost all of my use will be with a hot oven, like pizzas.
I'll buy the lime tomorrow , then see what the bag says about mixing. Kiko Denzir says a basic lime plaster is made of 3-4 parts sand to 1 part lime, and just enough water to make it workable. Seems clay would be a good addition. Maybe wheat paste? How do I make "rice soup"? I think you're suggestion of test batches makes sense so that's what I'll do this week.
