[papercreters] exterior waterproofing for papercrete wall

i think water may be wicking throo my papercrete wall where it is exposed to easterly rain conditions-
i wonder if i can waterproof it with silasec and grout made into a paint? i would leave the inside of the wall 'breathable'-
i just want to keep the rain from coming throo as this is meant to shield the patio from the rain! it is not a closed in building, rather a sort of shell with plastic windows...
the mystery to me about papercrete is that it absorbs water but must breath as natural buildings will- i love the softer, warmer 'feel' of papercrete compared to concrete surface and have used it as a render over a skeleton of cloth dipped in portland/bondcrete slurry supported on a wood and wire frame.
so far so good, don't want to wreck it with the wrong finish coat.
anybody have any ideas about this?
i thought to follow silasec's recipe for concrete paint but use grout
( which has no lime in it according to the people at the tile store)
as the grout comes in nice colours...
