Last Autumn there was a mention in a thread about 1950's brickwork
being porous.
About that time I had to drill a couple of holes in the gable wall -
it faces SW - and the debris was like a crumbly paste rather than
dust for about 15 - 20mm in.
The bricks are heavily patterned - a vertical herringbone groove -
which I think are Rustic(?) from c. 1950.

Is it worth treating the wall and, if so, what sort of gunk to put on
it?

There are 2 possibilities on this page

although the solvent-based one looks a bit nasty!

Any suggestions please?

I'd rather avoid coating the wall. I prefer something that soaks in and
that can easily be renewed by simply spraying on another dollop (I've never
like paint on exterior wood and use other treatments where possible).
