i absolutely love the vibe on this web site. warms my heart every time i see the jokes and easy going answers.
as to my question.
im on the verge of building a seed room in Turkey, in the black sea region, where humidity is heavy in winter time, and summer time can be also wet from time to time.
on top of that, we want to built this room inside the forest (im not sure if it will be more or less humid from an open space.)
i have experience with linseed oil protection, but i think this time wont cut it. we need a heavier and a more durable 'coat'.
i know lime plaster can maybe do the work, but i dont have experience in the application, quantities, or testing the formula before applying the bricks- soaking in water? trying to hose them down?
we want to make adobe stabilized bricks with lime... and then lime plaster on top..
well buddy, i am so sorry about nobody paying any attention that I will answer you myself.
The problem is that I dont know as much as i would like, and I am a begginer.
I dont know about cob, but in Los Pueblos mancomunados del estado deOaxaca, en México, there a lot of houses made of adobe and those can withstand months of humid climate. It rains (there) a quarter a year and is humid enough to have fog another six months.
They dont plaster the adobes, and the basement is always humid (the roof is not that big. I think they endure when the rain hits the walls diagonally and not directly from above.
The reason they withstand maybe that they use donkey dung or agua de nixtamal, I am nopt really sure.
If you still there, maybe i can send you a couple videos related to this matter.
