Techni-100 Application

GENERAL REQUIREMENTS

Refer to all instruction and other sections of this specification to determine the type and extent of work therein affecting the work of this section, whether or not such work is specifically mentioned herein.

Design and Detailing a Techni 100 System.

· The system shall be installed in strict accordance with current recommended published details and product specifications from the system’s manufacturer.

· The use of dark colors must be considered in relation to wall surface temperature as a function of local climate conditions.

· Minimum slope for all projections shall be 1:2 with a maximum length of 30.5 cm (12"), unless other manufacturer-approved detailing is shown on the construction documents.

Acceptable substrates

· Water-resistant core exterior grade gypsum sheathing ASTM C1396, Dens-Glass Gold® sheathing ASTM C1177, Aqua Tough Sheathing ASTM C1278, with 4.5 oz/yd² Fiber Glass Mesh.

· Fiberboard ANSI/AHA A 194-85, Plywood complying with US DOC PS 1-95, oriented strand board complying with US DOC PS 2-95 With Dupont Stucco Wrap and 2.5 # Galvanized Mesh.

ICF (Insulated Concrete forms) with 4.5 oz/yd² Fiber Glass Mesh

· Painted and otherwise coated surfaces of brick, unit masonry, stucco and concrete shall be inspected with professional applicator before application.

· The applicator shall verify that the proposed substrate is acceptable prior to the Techni-100 System installation.

Design Requirements

· The substrate systems shall be engineered with regard to structural performance.

· Structure to be designed in such a way as to minimize the transfer of stress from building movements to Techni-100 system.

Environmental Requirements

· Product shall be stored away from direct sun light and protected from freezing.

· Protect surrounding areas and surfaces during the application of the system.

· The system shall be protected when work ceases for the day or when an area is completed so that water will not infiltrate the system.

· Tops of the walls must be immediately covered to avoid water infiltration. To protect the system, copings or flashings shall be installed as soon as possible after the finish coat of the system has been applied.

· All sealants shall be installed in a timely manner.

· Sufficient labor and equipment must be employed to ensure a continuous operation, free of cold joints, scaffolding lines, etc.

Limitations

· Do not use on flat horizontal surfaces exposed to weather. Sloped surfaces must have a minimum slope of 6:12. Not recommended for large sloping surfaces greater than 12".

· Do not use as a roof finish.

· Apply only when ambient and substrate temperatures will be at least 40° F (4° C) and higher for at least 24 hours.

· Do not apply in direct sunlight. Applying in sunlight may result in cold joints or color variations. Protect from rain for at least 24 hours.

· Do not apply directly to exterior sheathing. Consult MCT Technical for approval for any applications not listed in this Product Installation.

Mixing

· Techni- 100 comes premixed from the factory. At the time of use, stir the finish thoroughly to redistribute the aggregate.

· For best results, stir at 300-500 rpm, using a heavy-duty ½” drill with a four point blade Mixer.

· Techni-100 does not require thinning.

Application Surface Preparation

Substrates must be sound and free of paint, dirt, grease, oil, efflorescence, form release agents and curing compound

Equipment: Trowel and Hopper gun type spray equipment or proven pump equipment.

Application Procedure

ICF Installation

· Apply 4.5-oz/yd² self-adhesive fiberglass mesh directly to ICF Foam.

· Apply Techni 100 as a Base Coat directly to Reinforcing Mesh with trowel to cover mesh completely.

· Apply and level Finish Coat during same operation to minimum obtainable thickness consistent with uniform coverage.

· Maintain a clean edge on trowel by applying and texturing continually over the wall surface.

· To achieve final texture apply Techni 100 desired finish (Fine, Medium, Coarse) with trowel, hopper gun, and approved pump equipment. Use a circular motion when spraying Techni 100.

· Applying with hopper gun, use a circular overlapping pattern, keeping the spray gun at a 90° angle to the surface and maintaining the same distance to the surface at all times. Be cautious of flooding an area with too much finish because it may appear shinier when it dries.

· Important: Always maintain a clean edge. To avoid unsightly color variations or visible lines, apply finish continually up to corners, joints or other natural breaks, and do not allow finish to stop or set up within an unbroken wall surface.

· Protect from rain and from temperatures less than 50° F for 24 hours. Provide longer protection as necessary during lower temperatures and/or higher humidity conditions.

Plywood, OSB, Fiberboard Installation

· Apply DuPont stucco wrap® Install Air Barrier over exterior side of exterior wall sheathing

1. Install Air Barrier after sheathing is installed and before windows and doors are installed. Install with drainage plane surface pattern in vertical position for proper draining. Install lower level barrier prior to upper layers to ensure proper shingling of layers.

2. Overlap Air Barrier at corners of building by a minimum of 12 inches.

3. Overlap Air Barrier vertical seams by a minimum of 6 inches.

4. Ensure barrier is plum and level with foundation, and unroll extending Air Barrier over window and door openings.

5.. Ensure barrier is applied over back edge of weep screed for proper water drainage.

6. Attach Air Barrier to wood, insulated sheathing board or exterior gypsum with plastic cap nails every 12” to 18” on vertical stud line with wood stud framing, and screws with washers to metal stud framing. When attaching to masonry, use adhesive recommended by manufacturer.

7. Prepare window and door rough openings as follows:

a. Prepare each window rough opening by cutting a modified “I” pattern in the Air Barrier.

1. Horizontally cut Air Barrier along bottom of header.

2. Vertically cut Air Barrier down the center of window openings from the top of the window opening down to 2/3 of the way to the bottom of the window openings.

3. Diagonally cut Air Barrier from the bottom of the vertical cut to the left and right corners of opening.

4. Fold side and bottom flaps into window opening and fasten every 6 inches. Trim off excess.

b. Prepare each rough door opening by cutting a standard “I” pattern in the Air Barrier.

1. Horizontally cut Air Barrier along bottom of door frame header and along top of sill.

2. Vertically cut Air Barrier down the center of door openings from the top of the door opening (header) down to the bottom of the door opening (sill).

3. Fold side flaps inside around door openings and fasten every 6 inches. Trim off excess.

8. Tape all horizontal and vertical seam of Air Barrier with DuPont™ Tyvek® Tape.

9. Seal all tears and cuts in Air Barrier with DuPont™ Tyvek® Tape.

· Expanded Metal Lath: The lath shall comply with ASTM C847-93. Furring and self-furring requirements shall be as set forth for wire-fabric lath. Weight is 2.5 lb/yd2. Other acceptable welded laths shall comply with ASTM C933-80 and other acceptable woven laths shall comply with ASTM C1032-86.

· Mechanical Fasteners: Type appropriate for framing as follows:

A. Heavy Gauge Steel Framing (20 to 12 Gauge maximum): Type S-12 bugle head screws, 5⁄8" minimum penetration into framing.

B. Light Gauge Steel Framing (20 Gauge): Type S bugle head screws, 5⁄ 8" minimum penetration into framing.

C. Type W bugle head screws, 16 mm (5⁄ 8") minimum penetration into framing.
