It is even more important to use the proper joint compound materials
because the liquid ones have  chemicals that we try to avoid.
Here are some powdered ones that we have recommended:

   - *Fast Set and Fast Set Lite:*  Purchase only Smooth set or Smooth Set
   Lite product and purchase only in bags, not in ready-mixed boxes. This is
   actually a patching compound with limited working time requiring skilled
   labor. Very hard and durable once dry. Zero VOC   Hamilton Drywall Products,
