I'm hoping there's a specialist around here who can help me
with advice about our walls.
It's an old house built of brick with no cavity. The oldest
bit (C1720) has solid walls 3 bricks deep and mostly these
are OK.
A later addition (C1840) has walls only 2 bricks deep and
it's these walls that are causing us some grief.
The outside is painted, (the bricks are too soft for
sand-blasting) and the pointing is apparently intact but I'm
happy to be advised on this.
The wet summer has brought damp patches inside these 2 brick
deep walls.
I am loathe to try and seal the walls either outside or
inside, the seal only breaks down sooner or later.
I feel sure there must be a way that the insides were
prepared/treated that could cope with damp weather
conditions when these walls were originally built.
Under normal conditions they would stay dry naturally - it's only the paint
that is causing the damp

We do keep a trickle vent open in the windows and the rooms
do get heated when we have the central heating on.
It's not a permanent affliction, there's precious little
damp in normal weather conditions.
The facts appear to be:
1) This wall gets some severe weather, and over the years, the brickwork has
been badly affected, probably by rain / frost cycles.
2) Some braindead clown has painted the walls in the past, in an effort to
hide some of the badly affected parts, instead of cutting them out and
replacing some of the bricks as was required.
3) You are now lumbered with a damaged wall which is getting steadilly worse
and will continue to do so until it is completely overhauled, because the
paint traps moisture in the brickwork.

You now have several choices:
1) Patch up and repaint - 'make do and mend', which is only a temporary
measure, which is what has already occured, maybe several times
2) Completely overhaul the entire wall, which means complete removal of all
of the paint by fair means or foul, IE sandblast the whole thing, then cut
out and replace any damaged bricks, and finally repoint the whole thing.

Mostly good advice, but

of the paint by fair means or foul, IE sandblast the whole thing, then cut
out and replace any damaged bricks,

that would be all the bricks, after you've sandblasted them. They're
soft 1800s bricks. Theres a water vortex thing that does the job, but
I dont recall the name.

When it comes to PP stuff it really is best to ask at that other
place.

The other place is simply you spouting stuff you can't get away with on
here.

for anyone reading if you ask there about whats discussed they can
point you to expert reports, SPAB etc. Its Stuart that cant be botherd
to get himself informed.
