Advice needed on Rendering a Garden Flint Wall

[mike912]

Hi all,
I would like to know what is the best process for rendering my garden flint wall. (Step by step if possible)
What would you recommend;
Sand/Cement mix?
How many layers of render?
Do i need a wire mesh for support?
Do i have to worry about damp prior to the job?
What are the best materials for the job?
What are the possible 'got ya' to look out for?
The wall it self is fair solid, but there are a few section that are lose.
Would like to get a much smoother finish.
You can see the size and state of it here http://www.flickr.com/photos/53006909@N ... 745454752/

Thanks for your time and advice.. :)

mike912,
Since it's a retaining wall and probably does not have any vertical dpm you will be wasting your time rendering - this will blow off at the first signs of frost.

why would you want to render it anyway? it looks just lovely as it is IMHO. i don't think that a render would enhance it at all, certainly not structurally.
