Hi I purchase a house recently and it has some gaps along the corner of the window frame outside and also some cracks along the inside of the frame work which has the moulding rendered over .. what can I use for the gaps in the corner of the the frame and also how about the cracks of the inside of the frame along near the window and the frame . I will then repaint over . I don’t think it’s wood structure . It could be a concrete type moulding ..
