Waterproof before o/s Masonary Paint ?

[yottie]

Am shortly having Weathershield Masonary Paint applied to a non-cavity outside wall which gets a lot of weather in the winter. The wall is usually damp inside in the winter, not helped by it being wall-papered.
Is there anything that can be applied, either inside or out to reduce this.
This is a 100 year old cottage which I never expect to be bone dry but would like to improve before the paint job if possible.

I have sprayed my house with a breathable waterproofer as my brickwork has become porus. I doubt that it can be painted over though.

if it was my cottage id battern and use insulated foil backed plaster board on all the outside walls save alot on the heating bills and keep the damp out. my fathers old 100 year old cottage was 9 inch solid brick walls but on the prevailing wind side a reed cavity wall had been used which must date back as far as house they must have put it in for same reason stop damp and heat escaping

With non-cavity walls, damp on the inside of the wall can be condensation not penetration - especially in winter.

I agree with the post above - foam and foil backed plaster board will fix the damp AND save £'s on heating.
