Everyday Usage: How Stucco Paper Fits Into Construction and Renovation
Stucco paper is the unsung hero of exterior wall assemblies wherever stucco is used. Its primary function is to act as a water-resistive barrier between your home’s sheathing (the wood or OSB boards) and the cement-based stucco cladding. While its name suggests it is only for stucco, this moisture barrier is also essential when installing brick veneer, stone, fiber cement siding, or even some siding panels.
Where You’ll Find Stucco Paper in Use
- New Home Construction: Installed over the framing and sheathing before metal lath and stucco are applied.
- Remodeling: Used to rewrap or repair moisture-damaged or outdated stucco walls.
- Custom Building: Applied under supplemental air or vapor barriers, or in special layered systems where enhanced moisture resistance is needed.
Everyday Benefits of Installing Stucco Paper
- Moisture Protection: Prevents rain, wind-driven moisture, and condensation from getting into the walls.
- Mold & Rot Safeguard: Keeps sheathing and structural supports dry, protecting against health and structural risks.
- System Durability: Helps your stucco cladding and the overall wall assembly last for decades.
- Repair-Friendly: Damaged stucco systems can often be repaired by removing and replacing the paper, saving full wall replacement.
Key Benefits of Using the Correct Stucco Paper
Choosing and installing the proper stucco paper brings a range of advantages:
- Water-Resistant Barrier: Its asphalt-treated or polymer-impregnated construction resists bulk liquid water while allowing some water vapor to escape, reducing trapped moisture risks in the wall cavity.
- Versatility: Works for stucco, masonry veneer, stone, or siding projects.
- Building Code Compliance: Most local building codes require a minimum standard of water resistance (often “60-minute” paper or 2-ply systems in high-exposure regions).
- Ease of Installation: Rolls out, is easy to cut-to-size, tacks on simply, and overlaps to create a shingle effect that guides water out and away from the wall.
- Cost-Effectiveness: Provides critical moisture protection at a relatively low material cost.
- Tear Resistance: Higher-grade, multi-ply papers, such as two-ply or Jumbo Tex, provide strong tear resistance during installation and after.
- Energy Efficiency: Reduces air leaks, which can improve the overall efficiency of the exterior wall.
How to Choose the Right Stucco Paper
1. Determine Your Local Code Requirements
Most building codes specify a minimum paper grade (such as 2-ply 60-minute or equivalent). Some allow one-ply in specific applications, though two-ply is highly recommended for superior longevity and protection.
2. Assess Your Climate and Exposure
- Dry, Low Rainfall: 10-minute or 30-minute paper may suffice, especially if combined with another underlying barrier.
- Wet, High Rainfall/Coastal: 60-minute, two-ply systems, or proprietary high-resistance options like Jumbo Tex are strongly recommended. For extra peace of mind, consider a double-layer application.
3. Evaluate Paper Ply (Single vs. Double)
- Single Ply (1-ply): Suitable for basic code compliance and lower-risk applications.
- Double Ply (2-ply): The industry standard. Delivers longer-lasting durability, greater water resistance, and reduced installation time compared to layering two single-ply sheets.
4. Select the “Minute Rating” (Weight/Thickness)
- 10-Minute: Thinner, easier to work with, but tears more easily and offers less protection.
- 30/60-Minute: Thicker, harder to tear, offers more robust water resistance.
- 60/30-Minute Combo: Offers a hybrid defense in systems where both rapid drainage and robust resistance are needed.
5. Consider Specialty & Proprietary Papers
Some brands offer building papers that far exceed code minimums (e.g., Jumbo Tex’s rating is 10x that of basic Grade D paper). These may cost more upfront but can save on labor and future repairs.
6. Environmental Concerns
Grade D and asphalt-based papers contain asphalt and are not recyclable, while some synthetics and polyolefin-based products have a lower environmental impact.
User Tips & Best Practices
Installation Do’s
- Start Straight and Low: Begin install from the bottom of the wall, aligning with the weep screed for drainage, and work upwards.
- Shingle Overlap: Always overlap each successive row by at least 4 inches horizontally (6 inches is safer). Vertical seams should be staggered and overlapped by at least 6 inches.
- Tight Sealing: Use staples or galvanized nails every 6 inches along supports, ensuring tight, wrinkle-free adhesion.
- Corners Matter: Wrap around outside and inside corners with a minimum 12-inch overlap to provide a robust, continuous barrier.
- Window & Door Flashing: Flashing should extend at least 6 inches beyond each side of openings. Paper should be lapped under or over flashing depending on location (bottoms lapped over, tops lapped under).
- Secure Edges: Use utility knives for clean cuts and always fasten down cut edges to avoid future peeling or bubbling.
- Mark Studs: Use a crayon or marker on the back side to mark stud locations for accurate staple/nail placement when attaching lath over your paper.
Installation Don’ts
- Don’t Use House Wrap Alone Under Stucco: Products like Tyvek alone are not substitutes for proper stucco paper, though they can be used in combination as an initial moisture barrier behind the paper.
- Don’t Skimp on Ply or Weight: Use minimum required two-ply or thick enough paper for maximum water resistance.
- Don’t Trap Moisture: Sufficient overlap and proper paper shingling ensures any water drains out and does not get trapped in the wall system.
- Don’t Install Over Dirty Surfaces: Surfaces under the paper should be clean and dry for best adhesion and protection.

Conclusion
Selecting the right stucco paper is critical for the long-term success, moisture defense, and durability of your exterior stucco system. Whether you’re working on a new build, a renovation, or making targeted repairs, understanding the differences in ply count, “minute ratings,” water resistance, and installation best practices empowers you to make informed decisions.
Investing in a higher-grade, two-ply 60-minute or better system is highly recommended for nearly all climates and elevations. This investment adds only a small material cost but can make the difference between a decades-lasting exterior or one prone to costly water intrusion and repairs.
Remember, professional installation, proper layering, attention to overlaps, and a willingness to exceed the bare minimum code requirements will virtually always pay off. The right stucco paper is your best defense against hidden water damage and the potential headaches of future wall repairs.
FAQ
What is the purpose of stucco paper?
Stucco paper acts as a water-resistant (not waterproof) barrier between exterior stucco cladding and the sheathing or framing of a building, directing any water that penetrates the stucco safely down and out of the wall assembly.
What does “10-minute” or “60-minute” mean in stucco paper?
These terms refer to industry-standard water-resistance tests. A “10-minute” paper will hold out water for at least 10 minutes before it seeps through in controlled testing, while “60-minute” resists for at least 60 minutes—indicating greater thickness and better water resistance.
Is one-ply (single ply) paper enough?
Single ply fulfills minimum code requirements in some regions, but two-ply is now standard due to superior water resistance, tear strength, and durability. Using two single plies instead of a manufactured two-ply roll is possible, but much more labor-intensive.
Can I use house wrap (like Tyvek) instead of stucco paper?
No. House wrap is not a code-approved replacement for stucco paper in exterior stucco assemblies. However, you can use it underneath stucco paper as an added moisture barrier.
How do I install stucco paper correctly?
Start at the bottom and work upwards, overlapping each row in a shingle-like fashion (at least 4 to 6 inches). Staple or nail every 6 inches along supports, ensure tight seams, and wrap corners with 12-inch overlap. Be thorough around windows and doors, integrating with flashing.
What’s the difference between Grade D paper and tar paper?
Grade D paper is an asphalt-infused kraft paper specifically designed for stucco and siding, while tar paper (asphalt-saturated felt) is made from felt and is commonly used as roofing underlayment. While both provide water resistance, Grade D is lighter and vapour-open, making it standard for walls.
How long does stucco paper last?
When properly installed and covered by stucco, it can last as long as the exterior wall itself—decades in most cases. However, repeated water infiltration from poor installation can shorten its lifespan.
What are some signs that stucco paper needs to be replaced?
Water stains, musty smells, visible mold, or damage to the stucco finish (like soft patches or cracking) are possible indicators. Repairs usually require removing stucco to access and replace compromised sections of paper.
Is stucco paper eco-friendly?
Grade D and other asphalt-based stucco papers are not recyclable due to their asphalt content. Some alternatives use recycled content or polymer bases. Proper disposal is necessary to minimize environmental impact.
Do I need special tools or skills to install stucco paper?
Basic hand tools (utility knife, staple gun, hammer, measuring tape) are all that’s needed. However, attention to overlap, tightness, shingling, and detail around openings is critical—so professional skills or experience are highly recommended to avoid costly mistakes.
Choosing the right stucco paper and installing it correctly will protect your most valuable investment—your home or building—against the ravages of water, weather, and time. Use this guide to navigate your options with confidence and ensure lasting results.
