Does anyone have illustrations of the proper way to seal penetrations through Stucco exterior?

I know how it's suppose to be done, but both my SMA manual and my TLPCA manual do not have illustration details for things like exterior outlets, light fixtures, gas lines, etc.

The EIFS part does, but I'd be called on the carpet in no time for using those!!!

Thanks All,

Hi,

If you've got the SMA manual you need to look at General Details. In there, you'll find diagrams for how to do

  • Expansion Joint Patch/Infill joints
  • Balcony Railings
  • Glass Block
  • Horizontal Pipe Railings
  • Sloped Sills
  • Hose Bibs
  • Stucco Wall Penetrations
It will depend on what you're trying to seal and at what stage you are trying to do it.

Hi,

It's right there at the first diagram. That is the technique used - they just don't bother to show you receptacles and recessed lights. Basically casing bead backer rod with a fillet of caulk.

Lol... Bob, you beat me at the punch and I was going to word my question pretty much as you did! Lol. I had no idea the Stucco industry had their own organization or manual. I bet that came about with EIFS. It used to simply be a part of masonry.

SMA manual... I want one! I LOVE my BIA and NCMA Tech Notes manuals. They are amazing.

Hi,

The SMA adopted the Northwest Wall & Ceiling Bureau's Stucco Guide about 4-5 years ago. NWCB has been around for about half a century and their guide, now SMA's guide, is the standard for 3-coat stucco.
