@ScoutingDad posted:Rick make sure you get Nara or Das, regular clay does not work, I tried one of the 10 pound clay blocks Mark. Nara is often on sale for under 2 a block. I think I used 6 blocks for my street. That was over 10 feet and got thick under the ties.
The box states it is air dry cly and talks about some of the things you mentioned about the surface it dries on and covering with wet paper towels to slow down the drying procees. That is something I will have to do as the humidty in my basement is lucky to be above 30% on average.
