Hi everyone, my brother in law has a house which he is trying to sell and it has a crack in the brickwork high up on the gable end. The crack has been there for years and is stable (not getting worse). However he has been told to fix it with some sort of resin and steel. Can anyone of you tell us what exactly needs to be done and is it a diy job or not ? He would like to render over the repair (resin) and paint it if this is possible ? Thanks for your consideration and advice in advance , STIX.
