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?
More or less all above ground wall bricks are porous. What you propose
is a classic mistake. Read SPAB's guidance on such things if you're
still tempted.
