Seismic Sealtite  is a one-step primary sealant for exposed areas where color matching is important. It has the same composition as Sealtite except that it has a puncture resistant, elastomeric coating on the exterior surface. The elastomeric coating can be factory colored to match most construction substrates or sealants. The joint is watertight and color matched. View the Dow 790 color chart for available colors.

Basic Use:  Seismic Sealtite is most commonly used to fill larger vertical and horizontal construction movement joints or joints where there is anticipated seismic movement. Seismic Sealtite works under its own constant internal pressure to provide a permanent, water tight seal eliminating costly water damage as well as allow for a greater degree of joint movement.

Typical Applications

• Pre-cast panels
• Retrofit joints
• Isolation joints
• EIFS
• Other joints requiring a resilient, waterproof seal
• Ideal for larger joints that require an architectural finish

Advantages

• Can be used in joints up to 8" wide
• Allows for up to 100% joint movement
• Provides a watertight, not just "weather-tight" joint
• Ease of installation, no mess
• Excellent compression recovery

Limitations

• Joints must be sized by measuring every 5-7 ft. (1.524 - 2.137 meters) to ensure gap opening is uniform and depth is sufficient for the supplied material.
• Do not install when substrate or ambient temperatures are below -14°F (-25°C) or above 95°F (35°C) without special procedures from Schul International Co., LLC
• Store material at a minimum of 68°F (20°C) for a minimum of 24 hours prior to installation, regardless of temperature at location of installation.
• Store materials in dry, enclosed area, off the ground, out of direct sunlight.
• Do not install when raining or snowing.
• Do not unwrap material until ready for installation into joint as packaging maintains material compression.
• Do not use scrap materials

Not Intended for Joints: 

• Submerged in water
• In contact with harsh chemicals
• In roofing applications
• Joints requiring pick resistance
• Cross joints in copings and projecting stone work
