Hi guys! This is my first post, so go easy on me, haha! 
We have just had a patio done. To ensure a solid patio base, the workmen dug a good 10" down and as a result, once everything was finished, a strip of unrendered and unpainted wall has now appeared (previously this was not seen as there was soil).
The strip is about 3 - 4 inches tall. I'd like to have ago at mending this myself.
What's the best way to fix this?
(a) Apply a proper render mix
(b) Apply external masonry filler
(c) Other - pls suggest
Once the strip has been filled, I will paint it with white masonry paint to match.
Thanks in advance for any help!
