OK, here comes the wall (I hope) It´s been hard because I live in a forest and my comunication is with a pen drive modem, it comes and goes with hicups and epilepsy.
The old wall (32 years) covered by roof.
Old wall uncovered because the roof colapsed (notice the diference in texture, but also 32 years old)
Old wall by the inside (uncovered, no roof). The white wall on the right is covered with adobe mix and painted with lime paint.
Inside the studio with good roof, also 32 years old. You can see the texture of the earth blocks is perfect.
Found the machine. I´ll try to take it out and make good pictures or a short video of it.
What we did was agregate 10% dry cement on the earth and 0,25% of sulfure (this prevents bugs an other parasits to live on the wall and if they lay eggs, these die. Beaten dry and than, after the tests we put or not put a little water on the mix.
Hope you like the results. We know this really works.
