rendering porch prep

[lancenotalot]

Hi,

My porch roof has been leaking for ages and with the cold winters the faces have come off some of the bricks.I m going to sort the roof out but also want to render the brickwork,what sort of prep is required with regards to coating it with something before rending?

Thanks
