Old damaged brickwork

[RobinClay]

So, as instructed by the Listing people, we stripped off the uPVC cladding from the 9" thick wall, and beneath we found old brickwork (in lime mortar) much of which brickwork had suffered from frost (presumably) - the outer skin had de-laminated in many places. This had been patched with render applied over the general area before the cladding was installed. In some places this render was applied over existing paint which is now soft.

I have cut out grooves along the joints in order to re-point (in lime mortar), but much of the render came off in the process, and much of what remains rings hollow.

The final finish is to be paint.

Should I re-patch the exposed damaged bricks with lime mortar? Or just paint? Should I use stabilising solution first?

I had thought to use Sandtex, which claims to be "breathable".

Any advice would be very welcome.

You need to replace the spalled bricks ideally.

Well, yes - the counsel of perfection. But so many have suffered it would probably be easier simply to re-build the entire wall than to replace them one by one.

And if doing that, then it would have to be re-built to modern standards of insulation, etc.. No bad thing, but WAY above our budget, as pensioners.


AND the Listing people would go (even more) bananas at the thought of that "historic fabric" being destroyed!
