Did you work it out in the end?

Hi, it was sanded down, cleaned with wonder wipes, and primed with Zinsser BIN, same process for the white painted areas that are ok.

I painted stairs in a combination of White and a dark grey tinted colour - ‘Noble Grey’ both in oil based Dulux trade satinwood. The white was just an off the shelf tin, they grey was a made to order tint. Both bought at the same time and used less that a week later in March this year. 2-3 coats...

Solvistrip and Peelaway won’t touch limewash at all, but they may get you back to bare limewash. I tried both at some point. In my case the top layer was a crappy plastic masonry paint - complete unsuitable for a solid brick wall, stopping it breathing properly. However, plastic masonry paint...

Thanks! I’ll also add it was a complete ballache, and pretty overwhelming at times. The chimney stacks really drained me - and the tops had to be rebuilt. Not a task i’d want to repeat tbh.

Well, i had one chap turn up while i was out, he used hydrochloric with a Torc machine and got a decent result, HOWEVER they left the wall absolutely reeking of acid - obviously not neutralised at all, and those fumes can easily flow in through airing bricks and corrode metals and fittings. It...

Did you sort it out? I somehow stumbled onto your album page thinking it was a forum post without any replies, so I wrote this list of questions before realising I was in the wrong place... some already mentioned/answered here. But here it is anyway. ################# I'll just fire some...

Right. But what I really don’t understand is the discrepancy between the traditional approach where you add the mortar, leave it harden a bit, then come back to wack it in with a churn brush and brush off. If you do this, it would seem impossible to then strike and trim the mortar which is done...

House is circa 1910, London yellow stock bricks. Original pointing is quite a light colour. I seen and been quoted for repointing in lime ranging up to around £50/sqm with a 'weather struck' finish. I'm also contemplating doing this myself, with some ready mix products like Limetec or similar...

Are you able to elaborate on what you saw going on via Wireshark ?

Vinegar is incredibly weak compared to hydrochloric brick washes of various strengths. I tried <10% and 18-20% which still took too much effort and knackered the lime mortar at the same time. Currently exploring acid gels.

The only unexplored options are wet grit blasting, particularly the TORC system, and perhaps some kind of acid gel or poultice (doesn't appear to exist). But anyway, is sanding the face of the bricks really that bad?

Right, well... for the record, I tried warm soapy water + stiff brush and didn't really get anywhere. The domestic brick cleaner, annoyingly unspecified concentration of "1-10% Hydrochloric" did kind of get somewhere but fairly ludicrous effort. Probably the most exciting movies on YouTube...

Well i'll try that later with warm water, soap and bristles and see what happens. I'm not sure which photo is photo three (i'm on a mobile) but the white brick closeup shows masonry paint on the right still present, on the left side it's just the limewash. The photo showing bare bricks on the...

With soap and water? Are you sure thay wasn't whitewash, rather than limewash? As I mentioned, the limewash appears to be harder than the bricks. Professional quotes are around £6k but they basically involve wet grit blasting...
