concrete rendered wall

[dannym72]

hi
we have a small wall in our front garden that had it's rendering come away and looked untidy.Fixed up the broen brick work.To repair it i got some concrete and rendered the wall .I have left it over night and now have noticed cracks of different sizes in it.How can I repair this to give a better finish before I paint it.It was my first attempt athis.I think the wall is either 10r 2 bricks thick and am unsure if there is a membrane in the inside.Any hep would be appreciated

First, don't use cement. Use a sand/lime only mix, and add some hair to it. It is more flexible than cement, and allows moisture move through it. Look up a video on the web to see how it's done.
