Hello
The back wall of my house has a serious damp problem - it looks like water penetration through 120-year old bricks (quite a few have faces sheared off) and some dodgy pointing. The recent downpours have really made this apparent - big damp areas of plaster on inside wall.
I’d like to protect/seal the bricks ASAP, but they’re presumably saturated. Do I need to wait for them to dry out (next Spring?) before I can do this? Thompsons Water Seal claims to be breathable, but *how* breathable? The last thing I want to do is to trap a load of moisture in the brickwork!
Any expert advice gratefully received.

Thanks all. I should stress that I just need a short-term solution - I’m getting a kitchen refurb in 18 months time and replacing the wall with bifolds (and fitting a proper DPC as well). I’ll be happy with something that can fend off the damp until then
