Sealing Damp from Wall

Hi Guys,

I've been asked to repair a garden wall where the paints peeling, hollow in places & top coat looks blown in a few places, although top coat looks too thin and poor scratching of scratch coat,

Anyway it appears that damp is penetrating from the back of the wall through in places, Is there anyway of preventing this or sealing this to stop it effecting my repairs, I was looking at using a webber render finished with webber sil TF as there is minimal thickness I have to play with. I just need something that would stop the moisture blowing what I apply

Cheers in advance

Sean
