If another coat of sprayed PC won't hurt, I would suggest mixing it:
- 2 gal wet paper pulp
- 1 gal latex paint of the color you want, keep in mind it will turn out lighter that the actual color.
- 1/2 gal pre-mixed dry wall taping mud
- 1/2 gal fine sifted sand
- 1/2 gal portland cement or one whole gal if you don't have morter cement
- 1/2 gal morter cement
Thin this mixture with more latex paint in need be, just to the point that you can apply it with your sprayer, this will not help your drying time but it will give you color on your walls and ceilngs and if you put a large fan in the room and leave a door open so the moisture can get out, you'll be further down the road to completition.

I am at the stage where the inside is still quite damp and I need to paint so I can put in a floor and desk. The best solution I have found is UGL Drylok which can be stained and apparently allows water vapor to still escape. My concern is that it will not allow water to escape fast enough and I may end up with rotting / mildew inside the papercrete.
