Hello, I’m about to start some light renovation work which includes filling settlement cracks and gaps in a new build and I’m looking for the correct products for the job. I’ve watched quite a few videos and read a few threads but still confused as to which filler is best. I know everyone has their own way of doing things but I just want to make sure that what I’m planning is correct. I’ve watched a video on repairing: skirting boards, nail pops, hairline cracks and one repairing a windowsill all by the same person. In the videos the guy uses a 2 part filler (Bonda - Decor Fill) except when coming to repair the windowsill gap (which was quite big) instead he back fills with caulk then tops it off with more caulk which I don’t understand as it was the same size gap and material as the skirting board, why not fill it with the 2 part filler to fill the big gap and THEN use the caulk to finish? Can I use Bonda - Decor Fill for the repairs I need? (I have attached images and numbered them to make it easier to reply starting with the hairline cracks moving to the bigger gaps). Thanks in advance.
