• STC 69 Tested: Tested in accordance with ASTM E90 for airborne sound transmission performance.
• Smoke & Sound Control: Helps prevent smoke passage and impede sound transfer through joints, penetrations, and openings.
• ±33% Movement Capability: Class II and III movement capability tested to ASTM E1399.
• Flexible & Elastomeric: Maintains a flexible seal for static and dynamic joint applications.
• Multiple Penetration Uses: Suitable around metallic and nonmetallic pipes, conduits, electrical cables, ventilation ducts, electrical boxes, and membrane penetrations.
• Joint Applications: Suitable for head-of-wall, bottom-of-wall, wall-to-wall, and other linear wall or floor joints.
• Vertical & Horizontal Use: Designed for interior wall and floor assemblies.
• Easy Water Cleanup: Water-cleanable acrylic latex formulation helps simplify jobsite cleanup.
• Low VOC: VOC compliant to CDPH Standard Method v1.2 and meets manufacturer-stated LEED requirements.
• ASTM G21 Tested: Independently tested to ASTM G21 with a rating of zero.
• No Mixing Required: Product should not be diluted and requires no mixing before normal caulk application.
• 2-Year Shelf Life: Minimum 2-year shelf life for caulk grade when properly stored.

Testing Standards: ASTM E84, ASTM E90, ASTM E1399, ASTM C834, ASTM G21, and air-leakage testing in accordance with modified UL 1479 and modified UL 2079.

Metacaulk SAS is recommended for interior, non-fire-rated vertical and horizontal assemblies where smoke, sound, or airborne particle movement through joints and openings needs to be reduced.

• Metallic and nonmetallic pipe penetrations
• Conduits
• Electrical cables
• Ventilation ducts
• Electrical, outlet, and receptacle boxes
• Membrane penetrations
• Through penetrations
• Head-of-wall joints
• Bottom-of-wall joints
• Wall-to-wall joints
• Linear joints in walls and floors
• Smoke partitions
• Sound-control assemblies

Joint Applications

Thoroughly clean the joint opening and remove loose material that could interfere with installation. Apply the caulk-grade sealant by gun, trowel, or pump to the required depth, then tool the material flush with the surface of the wall or floor. Use only approved backing material when required.

Penetrations

Thoroughly clean the opening around the pipe, conduit, duct, or other penetrating item. Gun, trowel, or pump the sealant to the required depth and tool it flush with the surrounding wall or floor surface to create a complete seal.

Application Conditions

• Apply between 40°F and 120°F (4°C–49°C).
• Do not dilute the product.
• No mixing is required for normal caulk application.
• Protect material from freezing.
• Store under protective cover in its original packaging between 35°F and 120°F (2°C–49°C).

Important Limitations

• Not designed for fire-rated assemblies.
• Not intended for immersion in water.
• Not intended for continuously wet conditions.
• Do not install on uninsulated surfaces exceeding 120°F.
