Tyvek® StuccoWrap

Stucco Wrap - W-TSW5 - Call for Pricing

For better drainage and stronger stucco

With a specially engineered surface texture designed for traditional and synthetic stucco systems in both commercial and residential construction, DuPont™ Tyvek® StuccoWrap® helps reduce susceptibility to cracking, improves stucco curing and channels moisture out of the wall.

Improve traditional or synthetic stucco

DuPont™ Tyvek® StuccoWrap® is a weather-resistant barrier with a specially engineered surface texture designed to meet the critical demands of both traditional and synthetic stucco applications. Tests show DuPont™ Tyvek® StuccoWrap® helps reduce susceptibility to cracking, improves curing of stucco, and better manages water and moisture that gets behind stucco facades.

• Won't absorb water
• Aids the stucco curing process
• Allows stucco to hydrate more effectively and develop more strength
• Adds dimensional stability to help prevent cracking
• Channels water and moisture to the outside
• Is highly breathable; dissipates moisture vapor
• Has good tear strength; 3 times stronger than paper
• Does not rot
• Is easier to repair with tape
• Retains strength when wet
• Has outstanding air infiltration protection

DuPont™ Tyvek® StuccoWrap® vs. Grade D Paper

DuPont™ Tyvek® StuccoWrap® is better than Grade D paper at managing hydration and remaining stable during curing. These two features result in a dramatic reduction of cracking in the scratch coat. Building paper can absorb water out of the stucco mix during curing. As the moisture content of the building paper changes, it expands and contracts. The movement can cause fractures in the scratch coat; shrinkage around the lath wire creates a void or gap. DuPont™ Tyvek® StuccoWrap® does not absorb water, helps maintain the moisture level needed for better curing, and doesn't expand and contract. It helps create a stronger stucco.

In flexural strength tests on traditional 3-coat systems, stucco cured on DuPont™ Tyvek® StuccoWrap® had up to 30% more flexural strength than stucco cured on 60-minute building paper. Less cracking means better stucco integrity and less chance that water will penetrate the facade. Ideally, each stucco layer should dry at a similar rate front to back. DuPont™ Tyvek® StuccoWrap® is better than Grade D paper at helping control moisture distribution in the mix during the critical early hardening. Improving the curing process results in stronger stucco.
