Oh well, I already ordered some 2 oz plastic. I did call DuPont, however, and they gave me a number to Material Concepts, who recommended "Hard Structure" type for tent floors. I see this is just type 10: http://www2.dupont.com/Tyvek/en_US/products/structure_types.html Old news, I guess. All Tyvek is gas permeable by its very nature.

I have read about others adding a coating, but that it peeled off after not too long. I have some "camp dry", that is 13% silicone, which I think would result in the same.

Yes, the ground cloth, itself, would dry quicker, if it is gas permeable.

My tent has good ventilation. I will be trying Tyvek after my 2 mil plastic is worn out.

Sorry if I am boring anyone to tears.
