Q: Can it be appied to a outside Wall.

Yes, it can applied to an outside wall. It works best that way.

Q: Can it be applied to a wallpapered and emulsioned wall? I just have a small patch in the window reveal needs covering.

You need to get the problem with the water ingress sorted 1st.The damp seal will stop any staining to the new paint. I would not apply this to the wall paper.
