I own a 1900 terrace house and the windows are upvc. They have been inset into where the previous window was and there are concrete sills. There is a layer of brick which goes around the window and this has been rendered or plastered upon then painted white (on the outside). The rest of the house is not rendered. Near the bottom corner and upwards for about 1 foot the render is blown out I have broken some of this away and you can see some wood (I presume where the old frame was) and a gap of about 5 mm, if I look further up it looks like there is a larger gap. I was wondering whether firstly when I break away all the blown render if I should fill the gaps with either mortar or expanding foam and then secondly what the best way to render back over with is. The job that has done before isn't particularly smooth so I think even I should be able to improve on it.
Lastly there are some minor cracks in the sills and render, I was going to open these out and then fill them with Touprelith F. Then put a smooth masonary paint on top, is this the best way to do it.
Furthermore, to seal around the UPVC and the window I will remove the current sealant and then use an exterior flexible UPVC sealant, is this also the best way to do it.
Sorry for the great number of questions, and I will upload some pictures shortly.
