We have hairline cracks in external wall of house. Only the one wall rendered; the rest brick. As the majority of the cracks emanate from edge of lintels, I think cracks are due to minute house movement over time against a very hard render.
Could anyone recommend a render mix/filler that is flexible and would accommodate small movements so cracks do not reappear in a year or so?
