I wasn't sure where to put this exactly but I know to use earthen plaster with cob for waterproofing so I put it here.

Anyway, we have a pond on our farm that is down in a ravine, basically, and we have a path and series of steps that lead down to it. About halfway down is a widened area that we cut a bench seat into the hillside which is a great place to sit and watch the water and be out of view of anywhere else. A private little retreat area. We don't want it to wash away, though, and thought if we could cob it and then use a plaster of some kind (rather than straight concrete) it would be a great place to maintain and maybe build a small patio and firepit near.

I've made cob before ... we build a cob bread oven that worked great ... so I know the formula for that, but I don't want to use yucky straight concrete to cover it. Is there a percentage of cement I can add to my cob mix that will make it waterproof/water resistant and help preserve the seat and steps? Or is there something else that can be done or added to help with this? I don't anticipate ever building a roof over this area as that would defeat the hidden quality of it and block the view of the stars. Thanks for your help.

Cob with 5 - 10% linseed oil gets really hard and waterproof (like concrete). You can add the mixture in a thin (less or about 1cm | 3/8") layer, or apply linseed oil to the drying cob for a few days (replacing water with oil).

Why cob and not wood? I imagine a thin (~2cm) wood planks would make a surface that isn't that cold to sit on.
