I'm sorry I have no idea about the answers to your questions, but was just wondering if your concrete decking is supposed to be "pitted" like that?
( is that the style of the decking or did you have some serious damage?)
I look forward to seeing the answers as I have some cracks in my concrete decking that I'd like to just "fill-in", but am not sure if it's something I should do or not...
good luck! :-)
