Some questions on how to rebuild the bucks in this 1950's CMU foundation wall.
We are replacing the 1"exterior foam that the coating failed on (it was a really brittle, sandy fiberglass concrete like finish) and I will be finishing it with Tuff II. As I was pulling the flashing off the window, I realized the bucks were wet and rotted, so all the windows are going to be replaced as well. I like the look on the recessed window like this, but I'm kind of afraid that wide sill is just asking to collect water again in the future so was thinking I would bring the window out flush like I see most other basement windows. I had some questions on doing this:
When I rebuild the bucks, I assume I need to have them extend the thickness of the foam past the CMU, is that correct? I see videos for wood framing with exterior foam, but nothing for finishing with concrete block though I assume it is essentially the same.
As you can see in the picture, the head board is only a 1"x, am I going to need to get a shorter window and change that to a 2"x?
What's the best way to attach the bucking to the cmu, tapcons? Construction adhesive? It is a 50's house so the blocks are rather old.
When I flash this, do I flash directly to the cmu?
I plan on talking with the city more when I go for permits, but I want to have a good plan in place prior and adjust as they tell me.
Thanks in advanced.
