STRATUM GUARD® I & II SYSTEMS
DSC440C
Moisture Drainage EIF Systems Over Wood Substrates
For An Extra Level of Moisture Protection
Dryvit® now offers an EIF system for use over wood substrates
that provides exceptional moisture drainage protection. The
Stratum Guard systems from Dryvit have been engineered
specifically for residential and light commercial construction.
Stratum Guard offers unparallel protection and insulating
performance for your wood-based building project.
Systems Components
1. Air/Water-Resistive Barrier Coating : BackstopTM NT (Texture) and Dryvit Aquaflash® Mesh
2. Dryvit Aquaflash System or Dryvit EIFS Tape and Surface Conditioner
3. Dryvit Drainage Strip adhered with Dryvit AP Adhesive
4. Dryvit Adhesive in vertical notched trowel configuration using the Stratum Trowel.
5. Grooved Insulation Board (Stratum Guard II)
6. Dryvit Reinforced Base Coat
7. Dryvit Finish
Same Outstanding Weather Protection and Product Features
With the Stratum Guard Systems, you get two levels of weather protection plus all the features
that have made our wall systems best in their class:
Energy Efficiency - The system incorporates an insulation board, which is installed on the
outside of the framing, effectively sealing thermal bridges, reducing energy loss and providing
a more consistent interior temperature.
Design Flexibility - Choose from a multitude of colours and textures to give the project your
distinctive touch. The Stratum Guard System allows for affordable and impressive
entranceways, window borders, arch-es, columns, sculptured looks and more.
Durability - Dryvit Systems have been tested and proven in exhaustive studies for impact,
fade and stain resistance. Dryvit’s DPR (Dirt Pickup Resistance) finishes and PMRTM (Proven
Mildew Resistant) finishes offer owners state-of-the-art performance. Dryvit systems, as with
all other exterior claddings, require nominal maintenance (refer to Dryvit’s Homeowner’s
Maintenance Guide, DS235)
Dryvit - Proven for Over 35 Years
Dryvit Systems Canada is an ISO 9001:2000 registered company. ISO standards have been
established worldwide as a common denominator for product excellence. Dryvit is the
recognized leader in EIFS technology. With leadership comes an obligation and commitment
to research and development. The Stratum Guard system is an example of our determination
to continuously evaluate market demands and develop new and exciting products.

INTRODUCTION
This document contains the Manufacturer’s Standard Specification for Stratum Guard Systems I and II. These
specifications follow the Construction Specification Institute’s 3-part format.
TAILORING THE DRYVIT MANUFACTURER’S SPECIFICATIONS TO YOUR PROJECT.
These specifications cover all the common ways of using the Stratum Guard System. Most projects use only a
few of the possible combinations of these materials and methods. To tailor the specifications to your project,
simply use those sections which apply. Also, it may be prudent to place certain parts of the Dryvit Stratum
Guard Specification in other parts of the project’s total specification, such as sealants and framing. The project
design professionals are responsible for ensuring that the project specifications are suitable for the project. For
assistance in preparing your specification, contact your Dryvit Distributor or Dryvit Systems Canada.
UNITS
English Units are included in parentheses after the Standard International (SI) equivalents thus:
3
12.7 mm (1/2 in)
16 Kg/m (1.0 pcf)
Please note that the conversions may not be exact but rather represent commonly used equivalents.
WARNING
The Stratum Guard System is designed as a drainage wall cladding system and is detailed to discharge
incidental moisture from within the System. Specifications should be followed and proper details adhered to, in
order to prevent water intrusion, resulting in possible damage to the System or other building elements. Care
should be taken to insure that all building envelope elements, including without limitations, roof designs,
windows, flashings, sealants, etc., are compatible with this system.

PART III-EXECUTION
3.01 EXAMINATION
A. Prior to installation of the Stratum Guard System, the contractor shall verify that the substrate:
1. Is of a type listed in Section 1.04 C.1.
2. Is flat within 6.4 mm (1/4 in) in a 1.2 m (4 ft) radius.
3. Is sound, dry, clean, free of efflorescence, connections are tight, has no surface voids, projections, or other
conditions that may interfere with the Stratum Guard System installation or performance.
B. Prior to installation of the Stratum Guard System, the architect or general contractor shall insure that all
needed flashings and other waterproofing details have been completed, if such completion is required prior
to the Stratum Guard System application. Additionally, the contractor shall ensure that:
1. Metal roof flashing has been installed in accordance with Asphalt Roofing Manufacturers Association
(ARMA) Standards and Dryvit Stratum Guard System Installation Details, DSC106C, or as otherwise
necessary.
2. Openings are flashed in accordance with the Dryvit Stratum Guard System Installation Details, DSC106C,
or as otherwise necessary to prevent water penetration.
3. Chimneys, balconies and decks have been properly flashed.
