Silicone calking for concrete, wood and metal?
Posted: Thu Aug 22, 2019 11:24 pm
I need to keep water from entering between my skirting's sill plate (pressure treated 2x4) and the concrete pad it's bolted to. The pad extends a good foot past the siding/skirting, in which case water tends to collect.
What caulking would work best?
Butted back against the sill plate (and skirt framing studs) will be Z-flashing that I plan to use for setting the bottoms of the new skirting (metal roofing material). This will provide a nice straight edge as well as to hold the skirting up from resting directly on the concrete and keep it from resting in water.
The Z-flashing, galvanized, is 3/8" for both seat and foot, so figure a bead would have to be a good 3/8" (a fair amount of caulking; but, I care more about doing things right than in sparing expense).
