The foundation of a quality stucco system starts before the lath ever goes up.
Proper installation of Tyvek (WRB), flashing, and felt paper isn’t just a box to check it’s critical to the long-term performance of the entire wall assembly.
âś… Water management matters.
When Tyvek and felt paper are installed correctly and integrated with flashing, they create a continuous drainage plane that directs moisture out, not in. Skipping steps or cutting corners here almost guarantees future water intrusion.
âś… Flashing is not optional.
Windows, doors, penetrations, and transitions are the most common failure points. Correctly layered flashing protects these vulnerable areas and ensures water sheds the way the system was designed to work.
✅ Lath and stucco are only as good as what’s behind them.
Once lath and stucco are installed, defects behind the wall are hidden until they show up as cracks, staining, mold, or costly repairs.
âś… Do it right the first time.
Taking the time to install WRB, felt paper, and flashing correctly protects the structure, the client, and your workmanship for decades.
Quality stucco isn’t just about the finish coat, it’s about respecting the layers that make the system perform.
