I'm building my first chicken coop, from an old trailer than broke down. The walls are being built with pressod, and I was thinking about making a clay/dung mix to cover the outside of the trailer in order to make it more weather resistant. Any thoughts? My concern is that it may not properly stick to the presswood, and would fall/cruble in large pieces as it dries out.
I'm not well versed in these materials but from what I've picked up elsewhere, incorporating the right amount of fibrous material, such as straw, in your clay dung mix can strengthen the wall/surface you're building. As for sticking to the building, using thin chicken wire (think stucco) on the exterior before applying your mix should help bind the material to the presswood and give it strength to hold together.
Definitely double check on these suggestions, as again I haven't worked with these materials, but when reading about cob I picked these things up.
And then we all jump out and yell "surprise! we got you this tiny ad!"
