Patching old render went titts up

[burty]

Morning,


I had to patch in some render on an old coach house last week which had cracks through to the old stone above two arches (pic attached), the patch is about 6mtrs long by 60cm high, the cracked area was hacked off, meshed over the cracks, scratched and had a go at getting the finish in the top coat, my best guess was to Tyrolean it and soften it with a damp roller. Obviously the wrong way cos when the paint hit it :RpS_scared: needless to say the customer wasnt happy as you can clearly see the patch so im back next week to sort it! :RpS_crying:


The finish is one I haven't seen before, it has some smooth lines here and there but the main texture is pitted unlike a pronounced (see pic), it looks to me like it may be a rolled finish?? does any one have any ideas on how to achieve the original finish?
I think its pretty unlikely the patch will be invisible and the wall is in a prominent area so I am now tempted to key the whole wall with a sbr and cement slurry and put a light Tyrolean over the area, could you Tyrolean straight onto the SBR slurry?

Any ideas?

ive tyro'd over SBR slurry before and it's still on 5 years later. thats a canny light texture to replicate, i would do the whole wall like you mentioned

Scrape any loose, slurry, scratch, Tyrolean whole panel, will stick out like a sore thumb otherwise..

Never try patching a texture, they never look right..

Lesson learnt??

I always tell my customers you cannot patch render, it usually always stands out.

i did an insurance job last week and it looks a right fookin bollox, but I did tell them before hand and if they wanted it to look good then the lot wanted to come off and be completely re-rendered, unfortunately some people only hear the price.
