• Fire Rated Protection: Designed to help prevent the spread of flames, smoke, hot gases, and water through construction joints and gaps during fire conditions.
• Flexible Elastomeric Performance: Cures to a flexible elastomeric membrane suitable for areas exposed to vibration, movement, and dynamic joint expansion.
• Multiple Application Methods: Can be sprayed, brushed, troweled, or applied with a caulking gun depending on project requirements.
• Ideal for Large Commercial Projects: 5 gallon pail packaging helps improve efficiency and reduce downtime on large-scale applications.
• Water-Based Formula: Low odor, water-based formulation allows for easier cleanup and VOC compliant installation.
• Excellent Smoke & Acoustic Seal: Provides effective smoke sealing while also functioning as an acoustical sealant for wall and floor assemblies.
• Freeze-Thaw Stable: Designed to withstand freeze-thaw cycles for dependable storage and performance.
• Paintable Finish: Can be painted after curing for a clean finished appearance.
• Mold Resistant Protection: Protected against mold growth in both wet and dry stages with incorporated biocides.
• UL & ASTM Tested: Tested to UL 2079, UL 1479, ASTM E1966, ASTM E814, ASTM E90, and ASTM E119 standards.

Ensure all joints and openings are properly prepared and packed with the appropriate backing material according to the tested firestop system design. Substrates should be clean and free from loose debris, dust, oils, or contaminants prior to application.

Metacaulk 1200 may be:

• Applied directly from a caulk gun
• Brushed or troweled from the pail
• Installed using approved airless spray equipment

For spray applications, recommended equipment should provide a minimum working pressure of 2500 PSI with a recommended spray tip orifice range of 0.015" to 0.025".

General Application Steps

1. Prepare joint opening and install backing material if required.
2. Apply sealant to required thickness per tested assembly design.
3. Tool or smooth material as necessary.
4. Allow product to cure fully before exposure to service conditions.
5. Clean tools and equipment with warm water before material cures.
