External wall - can I use K Rend HP12 without top coat?

[Blueplanet]

Hi

I have an external wall that is rendered with sand and cement and then painted over. One part has broken. Can I use K Rend HP12 without a top coat if I hack off the damaged section?

I was thinking using HP12 to the same thickness as the sand and cement either side and then just painting it over. Is there anything wrong with this approach? Thanks

Why not just s+c it?

You will be better off with ocr get it up thicker hp12 build up in layers an ocr will work out bit cheaper
