 Hello Everybody, 
 I’m building my house in Belgium and I just started rendering the bales on the outside with clay (loam). I added some ulexite (sodium calcium borate, a natural mineral) against fungus. I’ve also added soda (sodium carbonate). This lowers the viscosity of the clay so I can use less water which should give me less drying shrinkage. 
 Anybody any experience with these materials? 
 Best Regards, Cas  |
