Alis or aliz is a thin plaster layer for the interior. You can see how smooth it makes the walls. We chose to add a small amount of natural yellow pigment to warm the walls.
After many test batches we ended with the following recipe:
1 gallon water
1 gallon dry kaolin clay powder
1 gallon 70 grit silica sand
1 cup of borax (mold spore prevention)
10 cups of wheat paste (binder)
1 tbsp dry yellow pigment
