Mixing Instructions

General: Do not add any additives to Dryvit materials.
Opening Preparation Materials: AquaFlash and Backstop NT require initial mixing with a drill and paddle.
Adhesive and Base Coat: Mix Primus or Genesis with Portland cement and water, following specific instructions for consistency and pot life.

Mixing Instructions for Rapidry DM 50-75:

Add 5.2 L of clean potable water to a 19 L pail or mark 97 mm from the base and fill with water.
Slowly add Rapidry DM 50-75 while mixing with a "Twister" paddle at 500-1200 rpm.
Mix until uniformly wetted, adjust consistency with water or material.
Let set for 5 minutes, retemper if necessary.

Mortar Mixer Instructions:

Add 5.2 L of water per 20.4 kg bag of Rapidry DM 50-75.
Mix for 3-5 minutes, let set for 5 minutes, then mix again for 2-3 minutes.

Base Coat Instructions:

NCB: Mix to a smooth consistency, add water if needed.
Dryflex: Mix thoroughly before adding Portland cement, adjust with water if needed.

Primers and Finishes: Mix various primers and finishes with a "Twister" paddle at 450-500 rpm. Add water to adjust workability.

Specialty Finishes: Mix Ameristone, Stone Mist, TerraNeo, and Lymestone for one minute before application. Do not overmix.

Coatings and Sealers: Mix Demandit, Revyvit, Weathercoat, and others to a homogeneous consistency.

Rough Opening Preparation Options:

AquaFlash System: Ensure surfaces are clean and dry. Apply AquaFlash liquid and mesh to openings.
Dryvit Backstop NT: Apply when temperatures are above 4°C. Ensure surfaces are clean and dry.
Dryvit Flashing Tape: Apply surface conditioner before tape, ensure surfaces are clean and dry.

Dryvit Flashing Tape Application

Cut the tape to the required length, peel the release paper, and align it before adhering to the wall.
Ensure the tape covers the Backstop NT by 51 mm and turns into the opening.
Apply pressure with a hand roller to ensure firm contact with the wall.
Maintain a minimum overlap of 51 mm for end laps.
In cold weather, use a heat gun for better adhesion.

Sill/Jamb and Head/Jamb Intersections

Apply sill piece first, followed by corner splice and jamb pieces.
For head/jamb, apply jamb pieces first, then corner splice, and head piece last.

Substrate Expansion Joint Bridging Options

AquaFlash System: Overlap AquaFlash Mesh by 51 mm on each side of the joint, apply AquaFlash Liquid, embed the mesh, and apply a second coat.
Dryvit Flashing Tape: Apply surface conditioner, allow to dry until tacky, and position tape centered over the joint.

Water-Resistive Barrier Application

Two types: Backstop NT liquid membrane and code-compliant sheet membranes.
Ensure wall surface and temperature are suitable before application.
For sheathing substrates, ensure they are structurally sound and clean.
For concrete/masonry, repair cracks and ensure a clean, dry surface.

Backstop NT Application

Apply Dryvit Grid Tape on joints and edges before Backstop NT.
Backstop NT - Texture can be applied using roller, trowel, or spray equipment.
Ensure a continuous film at a dry thickness of approximately 3 mils.
For roller application, use a foam roller and ensure joints are dry before proceeding.
For trowel application, apply a continuous coating over the entire surface.
For spray application, use suitable equipment and ensure a uniform film.

Application of Backstop NT - Texture and Smooth:

Use a foam nap roller to apply Backstop NT - Texture, ensuring a smooth film. If material is pulled from joints, it indicates insufficient drying.
Smooth Backstop NT - Texture around windows and doors while wet.
Apply Backstop NT - Smooth using a roller or spray, ensuring joints are treated beforehand. Apply uniformly and check for voids after drying.

Sheet Membranes Installation:

Install in a weatherboard fashion following manufacturer instructions.

Accessories and Drainage Options:

A. Accessories: Install Dryvit Drainage Strip or Track at wall bases and openings. Use adhesive and ensure firm contact.
B. Mechanical Fasteners: Use specified washers and screws for different substrates, ensuring proper penetration.
C. Drainage Options: Install Dryvit Drainage Mat over water-resistive barriers, ensuring tension to minimize bulging. Use Tyvek StuccoWrap for drainage, ensuring proper lapping and flashing. Secure grooved insulation boards with mechanical fasteners.

Insulation Board Installation:

A. Inspection: Ensure insulation boards meet specified tolerances and are properly labeled.
B. Preparation at Terminations: Use Detail Mesh for wrapping at terminations. Optionally use Drainage Track for base and openings.
C. Mechanical Fastener Attachment: Install insulation boards starting from the base, ensuring offset from sheathing joints. Use specified fasteners and follow recommended patterns.
D. Adhesive Attachment: Mix adhesive as per instructions and apply using a notched trowel. Ensure adhesive ribbons run vertically for drainage.

Installation Procedures for Outsulation RMD System

Insulation Board Installation: Ensure uniform contact by applying firm pressure over the insulation board. Clean edges with a margin trowel and ensure joints are tightly abutted. Install subsequent rows in a running bond pattern with staggered vertical joints.

Wall Penetrations: For corners of openings, use L-shaped insulation pieces. Wrap openings with Detail Mesh and allow space for differential movement. Install J-Track at openings, extending beyond edges, and secure with corrosion-resistant fasteners.

Expansion Joints: Leave a 19 mm separation between dissimilar materials and at substrate transitions to allow for movement and sealant installation.

Slivering: Fill gaps greater than 1.6 mm with slivers of insulation board. Do not apply adhesive on sliver edges.

Aesthetic Reveals: Use a chalk line to mark reveals and ensure the insulation board thickness at the bottom is not less than 19 mm. Embed Detail Mesh in the base coat mixture for continuity.

Preparation for Base Coat: Wait 24 hours after installing insulation board before applying the base coat. Sand any irregularities and remove dust. Embed Detail Mesh in the base material mixture.

Reinforcing Mesh and Base Coat Installation: Inspect insulation board for flatness and damage. Apply base coat in two passes to fully embed reinforcing mesh. Use Panzer Mesh for high traffic areas and apply a second layer of reinforcing mesh.

Sealant Joint Preparation: Coat base coat surfaces with Color Prime or Demandit before applying sealant. Allow to dry for 48 hours.

Dryvit Primers: Ensure base coat is cured and dry before applying primers. Correct any irregularities and remove efflorescence.

Dryvit Finish: Ensure base coat is cured and inspect for irregularities before applying the finish.

Application Instructions for Dryvit Outsulation RMD System

General Application Guidelines: Dryvit finishes must be applied continuously to natural breaks like corners or expansion joints. Maintain a wet edge and use materials from a single batch to avoid color variations. Ensure sufficient personnel and scaffolding are available to prevent cold joints. Avoid applying in rain and ensure the base coat is dry before application.

Specific Finish Applications:

Quarzputz, Quarzputz E, Sandblast, Weatherlastic Quarzputz: Apply with a stainless steel trowel to a uniform thickness, not exceeding the largest aggregate size.
Sandpebble Variants: Apply slightly thicker than the largest aggregate size and use a horizontal trowel motion for uniformity.
Freestyle: Apply to a thickness not greater than 1.6 mm, with texture not exceeding 6.4 mm.
Weatherlastic Adobe: Apply a coat of Color Prime, followed by two coats of Adobe for desired texture.
Ameristone, Stone Mist, TerraNeo, Lymestone, Custom Brick, Reflectit: Follow specific application instructions as per respective data sheets.

Coatings and Sealers: Coatings like Demandit, Weathercoat, Revyvit, Weatherlastic Smooth, Tuscan Glaze, and SealClear should be applied over Dryvit finishes, not directly on the base coat. Specific application techniques include using brushes, rollers, or spray equipment, ensuring even application and avoiding dry rolling.

Maintenance and Repair: Refer to DryvitCARE EIFS Repair Procedures for maintenance guidelines.
