stucco metal Z flashings countering stucco metal drip screed protect your mudsill and investment
Howdy all, I’m going over a code requirement for protecting mud-sills for code and cosmetic reasons in this how-to stucco video.
Is it necessary? Yes, and it’s a permanent solution to protect the wood mud-sill of your home.
Unless you’re the homeowner and don’t want the mud-sill or mud plate to rot out on you in less than ten years.
Have I seen this detail with just paper? Yes, this means the piece was tacked as it should be on the wall diagonally, then bent to be used as a one-inch on a flat surface where the foundation protrudes.
This can last up to 5 years or perhaps ten or even longer if quality paints are used to prevent rainwater intrusion.
However, when the sun hits these areas and brings with it a season’s of say 80 to 100 degrees, the wood naturally can swell, pushing the stucco outward creating a crack as the paper is not a stable barrier for the horizontal surface, this can be the beginning of wood rot and water penetrating issues that can’t be noticed as they usually bellow the floor level.
I’ve seen some worse-case scenarios where the entire mud sill rotted for similar reasons. And had to be opened and wood with stucco replaced. Surely you don’t want to keep me employed.
Can you bust the stucco of the foundation so that a drip or weep and be used? Sometimes, I have had my share of trying to remove stucco welded on or what we call an excellent mechanical bond to a freshly poured foundation.
Two out of ten times, especially in homes over 80 years old.
For a small amount of extra time, it’s best to place any galvanized Z flashing to protect the bend from horizontal to vertical, thus, with no worries about futures problems.
Stucco metal weep/drip screeds were not invented, thus code or required until about 1980.
Another excellent code a couple of years; required stucco stud walls to have plywood nailed on.
Man, we loved that code as we used to stretch the wire lath and nail it to just the studs, where we would lose much stucco between the stud bays.
Yea, I’m ancient as we used to lath over just studs.
