Hi, I have had some building work done which involved moving my back door and putting a window where the door was. The house is rendered with a smooth finish and the openings were cleanly made with a disk cutter. What I would like to know is what sort of render bead you would recommend (plastic, Stainless??) and how exactly I can redo the corners. Do I get stop beading and put the stop flush with external wall or do I need to cut back some more of the external so that a proper corner bead can be used? I'm not sure how clear my explanation is but if you look at the door or window opening you can see a clean cut through the render then the brick and I need to render this return. Also I have a concrete lintel over the door. How would you fix mesh to this for rendering - drill and screw?
