I use a light sprinkling of sand and recently started adding a sprinkle of PDZ on my poop board. The poop just sits on top of the sand and I rake it off onto a hardware cloth screen and then dump it a bucket then it goes into the compost pile. It is only lightly coated with sand and PDZ. I have clay soil so, once it's composted, the little bit of sand does a good job of helping to break up the clay soil.
