Hi all,
here are some pics of a job I did. For a post office on Manchester. They already had someone in to render and he smoothed the wall but was set back 70mm the client wanted the wall flush with existing and matching with dashing. Here's the process of work wat I did. You can notice that eml was attached mid project that was to hold back the existing render so I could start a fresh with getting my current wall flush. I grinded out lines to provide a key for my 1st coat of render not ideal but only process I thought that would work.

Any tips on to make it easier or quicker please let me know

Cheers all

Is the original dashing that thick ?? Surely that was a garage door or something and the brickwork has been put in set back ?
 
Yea the brickie said that the foundations were set back it was a shop front made out of alley. He walled up that far back and rendered himself?????
I had to cut the lines in and build up to s thickness were I could start again with the mesh fix it back to block work to hold it back. Then have a suitable background to work from


P.s any one come across pebble dash with 20-30mm aggregate?? 1st coat was sand and cement and the 2nd was a white cement with the 30mm aggregate dashed in? Never come across it.
 
Yea just a cake load of paint throughout the years. It's all done and completed just wondered if any one has come across 20-30mm Canterbury spa as that's way it looked liked?

No not Pebble dashing (dry dash) with 20 to 30mm but lots of rough cast (wet dash). Can think of a few ways the brickie could of brought the brick or block work out tho.
 
So what's the process with wet dash? Sand and cement 1st n 2nd coat while the second is still wet.
I'm guessing you mix your aggregate with a cement/sand slurry and apply like u would dry dashing?
 
You more or less have it there Ashley only the slurry has a rake of lime in it and you don't dash it onto a wet coat.
In fact just going off what I can see in the photos & the size of the stone, I'd bet a tenner that it is indeed wet dash.
When layers of paint come away after many years it can sometimes lift the slurry a little too exposing some of the stone.
 
That's fair enough. Feel embarrassed that I've never come across this seeing as I'm 28 and been doing it since I was 16. I don't know if you read the earlier comment but this slurry was a white cement base is that common in wet dash?
 
Yes, another pointer towards it being wet dash also.
Nothing to be embarrassed about, it's hardly ever seen in some parts, whilst in Scotland and Ireland its plentiful, also parts of the south so I'm told
 
I'm from leeds it's all pebble dash sand and cement and now k rend or similar products. ( that I would love to get involved with) had a days course on it but can't find a team that will bring me up to scratch with it. Plus 95% of my work is skimming
