Patching a small area of render

[rubble2]

I am going to paint a rendered outhouse wall with masonry paint, there are a few small areas near the top of the wall whee the render has fallen off and I would like to patch these prior to painting.

As I say, this is only an outhouse so I am not looking for a perfect repair but I would like for the repaired area to be as durable as possible.

So, what is the best way to approach this please? How would I need to prepare the surface before patching and - given that it is such a small area - can I use some sort of premixed mortar product from the likes of Wickes or a local builders merchants rather than buy separate sand sand and cement and create my own mixture?


Thanks

For what it is I would give it a good wire brushing then go and buy some Rapid set mortar mix, wet the area you are going to "render " and trowel the muck on then get a sponge and lightly rub it up to match the existing and let it dry properly then paint it.... a little trick with rapid set is , you can add a bit of sharp sand with it mix it and it should match your old render....
