WATERWAY WEATHER BARRIER 9714
Description
WaterWay 9714 is a nominal 3/16 inch thick drainage product consisting of a nylon core of fused entangled filaments and a geotextile fabric bonded to one side. WaterWay 9714 is designed for use with traditional stucco, EIFS, cultured stone, and other wall cladding applications as an exterior wall drain. The rainscreen provides a drainage path & ventilation for incidental moisture between exterior wall finish materials and weather resistive barriers.
Recommended Applications
- WaterWay Drainable Stucco Assembly
- Behind EIFS
- Behind Traditional Cement Stucco
- Cement Siding
- Behind Cultured Stone
- Lap Siding
Features and Benefits
- Excellent Durability – Class “A” Fire Rated
- Surpasses EIFS / AC-24 Drainage Criteria
- Conforms to irregular surfaces with complete and effective coverage
- Continuous flow even under high loads
- Long rolls reduce installation costs by eliminating interlocking and excessive seams
- Dimensionally stable in hot weather – remains flexible in cold
- Continuous ventilation when properly designed – Equalizes pressure
- Redirects & draws moisture away from vulnerable wall sheathing materials
- Filter fabric assures an uninterrupted drain path that remains clear of stucco or mortar

Installation Procedure
These suggestions represent generally accepted procedures for successful installation. It may be followed, modified, or rejected by the owner, engineer, contractor or their representative to accommodate project specific requirements.
Prior to installation the contractor’s responsibility is to ensure that:
- The substrate is sound, that there are no voids or other protrusions or conditions that would interfere with the drainage plane. Acceptable sheathing types include code compliant exterior grade plywood, oriented strand board, water-resistant gypsum and others. Consult your local building code for approved materials.
- The substrate is flat or plumb within 6.4mm (1/4 inch) in a 1.2m (4-foot) radius.
- Windows and doors have been properly flashed and sealed and also that roof flashings have been properly installed. Refer to “Installation Guide for Flashing Windows/Doors ETF 201” latest edition (Available upon request).
- Weather resistive barrier is properly installed to allow drainage without water penetration.
Attachment to Sheathing with Weather Resistive Barrier
- For wall application work from bottom to top. Attach fabric side out with flap down to assure proper shingling. Wrap the building completely, butt tightly at all door, window and other building materials (electrical boxes, air conditioning units, etc...), stopping at all wall ends. Install drainage mat so that it lies flat against the wall with adequate corrosion resistant fasteners to hold in place until cladding material application is complete.
- If specified cladding is stucco, EIFS or cultured stone veneer, at the bottom of the mat, place a foundation weep screed. Weather barrier and mat may be placed over top of the back leg of the weep screed to create the proper shingle effect and support moisture drainage.
Storage & Handling
WaterWay 9714 should be stored at temperature between 50 degrees to 90 degrees, out of direct sun light.
