Triarch's Duroplex system first entered the market in 1985. Over the years the product line expanded to include a wide range of decorative and performance products such as Plexture(R), SKIMM(TM) and FRESCO(TM) coatings. In 2003 Triarch was acquired by Dryvit Systems, Inc., the North American leader in exterior insulated wall systems. The acquisition caused the company to relocate from Houston, Texas to the current headquarters in West Warwick, Rhode Island. Triarch materials are produced in ISO 9001 & 14001 certified facilities. All Triarch products conform to sustainable building protocols as detailed in LEED and Green Seal Indoor Air Quality documentation.

DELIVERY, STORAGE, AND HANDLING
Deliver materials to jobsite in the original, new and unopened packages and containers bearing manufacturer's name and label, and following information: Name or title of materials, manufacturer's stock and/or batch number, date of manufacture, contents of containers including color name and number.
Store materials not in active use in tightly covered containers. Maintain containers in a clean condition, free from foreign materials and residue. Protect from freezing and maintain temperatures below 100 degrees F (38 degrees C). Keep materials stored in an orderly and organized manner to reduce the risk of error. Do not stack materials more than three containers high. Protect from fire hazards.
Handle materials to avoid damage.
Apply materials only when surface temperature is between 60 and 100 degrees F (15 and 37 degrees C) and expected to remain for 24 hours. If conditions cause rapid drying of the materials before proper finishes can be completed, eliminate breezes, fans or other air movements which contribute to the problem, and, if necessary, dampen the substrate with finely misted water just prior to application.
Protect finishes from casual impact and for a period of forty-eight hours after installation. Protect from heavy traffic for a period of at least three days. Protect all surfaces and adjacent areas not intended to be coated and clean immediately any spillage, droppings, or other extraneous contact of the materials with other surfaces.
Coordination of Work: Review other contract specification sections in which prime paints, raw substrates, or other substances might be present to insure compatibility of total coatings systems. Upon request from other trades, furnish information or characteristics of coating materials provided for use to insure compatible substrate materials and finishes are used.
Ensure that products of this section are supplied to affected trades in time to prevent interruption of construction progress.
Manufacturer's Warranty: Provide manufacturer's standard 10 year limited warranty.
Acceptable Manufacturer: Triarch, which is located at: One Energy Way; W. Warwick, RI 02893; Toll Free Tel: 800-537-6111; Tel: 401-822-4100; Email: request info (email@example.com); Web: www.triarchinc.com
** NOTE TO SPECIFIER ** Delete one of the following two paragraphs; coordinate with requirements of Division 1 section on product options and substitutions.
Substitutions: Not permitted.
Requests for substitutions will be considered in accordance with provisions of Section 01 60 00 - Product Requirements.
** NOTE TO SPECIFIER ** Texture and finish must be selected prior to biding because of wide differences in labor costs for different application techniques. The CS# designation below provides a reference standard to the approved design control samples. The CS# is typically found on the upper right area of the design control samples originally created by Triarch. For samples taken from the Triarch Architectural Portfolio, the finish name is sufficient for specification purposes and the CS# specification may be deleted. For Specification writers who cannot use Duroplex's proprietary name, use the last sentence of Section 2.01 as the materials specification. Selection of texture, color and a CS# number are still appropriate for a specification that only refers to TEXTURED ACRYLIC COATINGS.

Do not begin installation until substrates have been properly prepared. If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
Perform preparation and cleaning procedures in accordance with manufacturer's recommendations and as herein specified, for each particular substrate condition.
Remove hardware, hardware accessories, machined surfaces, plates, lighting fixtures, and similar items in place and not to be finish coated, or provide masking or other protection prior to surface coating operations. Following completion of coating of each space or area, reinstall removed items.
Clean surfaces to be coated before applying any materials. Remove oils and grease prior to mechanical cleaning. Program cleaning and coating so that contaminants from cleaning process will not fall into wet or newly coated surfaces.
** NOTE TO SPECIFIER ** Delete the substrate preparation not required.
Drywall: Drywall shall be prepared to industry acceptable standard for hanging vinyl wall covering. Remove excess gypsum compound dust. Do not prime or seal the drywall except as specifically recommended by texture acrylic coating manufacturer. For fast drying conditions, dampen surface slightly with a light spray mist of water just prior to application of acrylic wall coating materials. For damaged drywall, or after removal of old wall covering, patch/repair as needed to obtain a smooth surface and apply GARDZ High Performance Sealer by Zinsser following the manufacturer's label directions.
Cementitious Substrates: Prepare cementitious surfaces such as concrete, concrete block, cement plaster, and similar items by cleaning to remove dust, grease, form release agents. Patch all major holes and honeycombs using structural grout manufactured for the purpose as specified in the concrete specifications. Grind all projections above the planar surface until flush. Fill, and float smooth all recessed form seams and other minor imperfections using either SKIMMSYMBOL 226 "Symbol" 10 Acrylic Surfacing Compound, or REFORMIT as manufactured by Triarch Industries. Allow surfacing compound to dry at least 24 hours under nominal conditions. If necessary, dampen dry Cementitious surfaces just prior to installation of acrylic surfacing compound materials.

Water sensitive materials such as gypsum based products shall not be used for skimming over concrete or CMU surfaces.
Ferrous Metals: Clean free of oil and surface contaminants with non-petroleum based solvent. Prime all bare metal surfaces with a good quality rust inhibiting primer prior to application of any textured acrylic coating materials. Test adequacy of adhesion of primer to substrate prior to application of texture coating.
Galvanized Surfaces: Clean substate free of oil and surface contaminants with non-petroleum based solvent. Prime with good quality primer designed for galvanized metal surfaces. Test adequacy of adhesion of primer to substrate prior to application of texture coating.
Existing Painted Surfaces: All previously painted surfaces shall be sound with the paint firmly adhered. Test adhesion of existing paint in random locations prior to application of texture acrylic coating. If surface is dusty or dirty, clean surface with a mix of household ammonia and water (1 part ammonia to 3 parts water) to remove oils, dust, etc. If a high gloss paint that will result in poor adhesion, lightly sand surface to improve adhesion (total removal of gloss is not necessary). Test adequacy of adhesion of primer to substrate prior to application of texture coating.
Stir materials before application with a power drill and a drywall compound paddle. Stir at approximately 350 RPM for two minutes while removing material from all sides and bottom of the container. Stir only as much material as will be used in a four hour period or re-stir material left sitting in excess of four hours. Retain lid on containers until the material is in actual use. If hardened material accumulates on the sides of the container, carefully remove the hardened material, taking care to not allow any hardened material to fall into the wet material.
Thinning: Thinning may be done with small amounts of clean water. Comply with manufacturer's written instructions for thinning.
General: Apply coating materials in accordance with the manufacturer's instructions and recommendations as required to achieve the appearance of the approved samples and performance as specified herein. Coating materials shall be used as a system that may include primers or under coatings as required by the manufacturer's installation directions.
Final dry film thickness shall be a minimum average of 20 mils (0.5 mm). Coat surfaces behind movable equipment and furniture same as similar exposed surfaces.
** NOTE TO SPECIFIER ** Some finishes require Primer that is supplied with the kit of materials. Other finishes use Undercoat that serves as both primer and base coat for the finish. Select either C. or D. or both C & D below for the particular finish or finishes selected for the work, but note that Primer and Undercoat are never used on the same area.
For Finishes Which Require Primer: Apply acrylic coating manufacturer furnished primer with a 1/4 to 3/8 inch (6 mm to 9.5 mm) nap paint roller at a coverage rate of 240 square feet (22 square meters) per gallon. Allow to cure until firmly set (normally 1 to 2 hours at 70 degrees F (21 degrees C).
For Finishes Which Require Undercoat: Apply factory supplied undercoat at a rate of 250 square feet (23 square meters) per 65 pound (29 kg) net pail. Apply with a texture sprayer to achieve visible coverage. Wet film material should be a minimum of 20 mils (0.5 mm) thick. Apply undercoat to a uniform level finish without holidays or runs.
Apply finish coats in accordance with manufacturer's instructions and all finishes match quality samples previously approved by Architect.
