After twenty-five years of formulating, testing and manufacturing vertical walls products, Stuc-O-Flex International, Inc. understands the appearance of any project is the one element that immediately reflects the quality and integrity of the building, as well as the construction team involved. Our mission is to compliment those efforts with products of the highest quality and enhance cladding performance through Rainscreen configuration.
Stuc-O-Flex International created America's first Breathable Elastomeric Acrylic Finish back in 1981. More recently we've advanced the science of vertical wall Rainscreen in drainable Stucco, Stone, EIFS and siding assemblies to new levels with technologies unprecedented in past years. Unparalleled expertise in Acrylic Polymer Chemistry and our WaterWay™ line of Rainscreen Drainage Mats assures extended service life and exceptional appearance on your completed projects. Whether your design requires a decorative textured coating, direct applications to substrate sheathing, EIFS, Stucco, ICF finish systems, Drainable Rainscreen assemblies or applications to enhance standard metal building construction, no company offers a broader selection of wall cladding and configuration options.
Unequaled growth over the past two and a half decades and a listing in INC. Magazines' 500 Fastest Growing Companies reflects our philosophy and commitment to innovation, research and development, and uncompromising quality control.

PART 3 EXECUTION
 
3.1
EXAMINATION AND PREPARATION
A.
If preparation is the responsibility of another installer, notify Architect in writing of deviations from manufacturer's recommended installation tolerances and conditions.
B.
Do not proceed with installation until substrates have been properly prepared and deviations from manufacturer's recommended tolerances are corrected. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
C.
Commencement of installation constitutes acceptance of conditions.
3.2
INSTALLATION
A.
Install in accordance with manufacturer's written instructions and recommendations as applicable to specified application.
B.
Install sidewall sheathing material over framing.
 
** NOTE TO SPECIFIER ** Delete if not required.
 
C.
Apply building paper and housewrap in compliance with manufacturer's instructions.
D.
Rainscreen Drainage Mat:
1.
Horizontal Application: Work from bottom to top.
2.
Vertical Application: Work from a corner.
3.
When using product with attached weather barrier install with flap up to assure proper shingling. Wrap the building completely, covering all door and window penetrations, stopping at all wall ends. Install Drainage mat so that it lies flat against the wall substrate.
4.
If wall is designed as a venting wall, ends should be terminated at a furring strip of matching thickness to prevent air movement to adjoining wall.
5.
At all window and door openings, cut tight to vertical part of window, door casings.
6.
Take care not to cut or damage waterproofing and weather barrier.
7.
If finish cladding is stucco, EIFS or manufactured stone veneer, at the bottom of the mat, place a foundation weep screed, a "J" weep hole termination bar or flashing with weeps. Weather barrier and mat should be placed over top of the back piece of the weep screed, termination bar or flashing to create the proper shingle and water management.
8.
For other finish cladding, attach a 6 inch (152 mm) wide piece of insect screen material continuously along the bottom edge of the Drainage mat, 3 inch (76 mm) above bottom edge of the Drainage mat. Fold over outward facing surface of installed Drainage mat. Attach with a large head nail to hold screen in place until cladding is applied.
9.
For top vented walls follow a similar procedure at the top of the Drainage mat.
10.
If wall is designed as a venting wall, at wall terminations, place a wood termination strip along the outside edge of each wall to create a wind dam for negative wind load.
11.
Refer to manufacturers "Installation Guide for Flashing Windows/Doors" for additional detailing recommendations and instruction.
12.
Maximum exposure of WaterWay Rainscreen shall not exceed 30 days, prior to cladding installation.
E.
Install specified siding or cladding directly over WaterWay Rainscreen Mat in compliance with manufacturer's installation instructions within 30 days from application.
3.3
CLEANING AND PROTECTION
A.
Protect installed work from damage due to subsequent construction activity on the site.
