I have a tudor that was built in the 80s. On the second level it has exterior stucco, but it does not appear that the stucco was applied as a paste. Rather, it looks like there were sheets of drywall-type board with a thin coating of stucco applied. Snow collects on the cedar borders, and has rotted the stucco in a few spots. I wonder if there is some type of plaster that I can use, similar to joint compound, to fill the areas where the stucco has rotted. ANY ideas or suggestions are greatly appreciated!!!
