I had a prehung door done today.
Problem 1:
The aluminum threshold has a minimum @1/16" gap between it and the rapid-setting cement threshold installed underneath and 1/16" rising to 3/16 for the last 7" of its run where the cement threshold is not level.
I need something to fill this gap. Across the 1/16" deficieny, I am thinking an epoxy, polyurethane or other compound shot underneath the aluminum might do. In the last 7" of the threshold were the gap widens to 3/16"-- and I fear weighted flexing may result in distortion of the threshold--my first notion is one of the fillers already mentioned supplemented by composite shims that the fillers fix in place.
My requirements for a filler are UV toleration and/or paintability, duration, waterproof and minimal flexibility.
Problem 2:
The outer lip of the rapid-setting cement sill where it thins from the main body of the pour shows numerous cracks as pictured. If I could just coat the sill with something to prevent its further deterioration and improve water resistance, I will. Any good ideas?
Through a tedious attack with a diamond saw and diamond grinder blades, I could try to cut back as much of the lip as possible to reach the "apparently" ( or at least comparably) sound main body of the pour. Note, without X-Ray vision, seeing through the cement sill is not going to work. If I could cut/grind/carefully break the unsound lip material away, a new lip of concrete could be poured in place of the removed material. Because the door and jamb are in place and obstructing my access, this will be a challenging task.
I know this entire situation is an abortion. The door is in place and
it isn't going anywhere. The installer is a friend. He screwed up and I'll fix this by effort and with your guidance. FYI, the brick landing is way off level, which makes everything level look wacky.
Any and all ideas are appreciated.
