Frequently asked questions
Adhesives and sealants serve different primary functions:
Construction adhesives are formulated to join materials together with strong bonds that resist forces trying to separate them. They typically offer:
- Higher bonding strength
- Less flexibility
- Faster curing times
Sealants are designed to fill gaps and create flexible barriers against moisture, air and contaminants. They generally provide:
- Greater flexibility and movement accommodation
- Weather and UV resistance
- Lower bonding strength than adhesives
- Waterproofing properties
Many modern hybrid technologies combine the best properties of both adhesives and sealants, delivering strong bonds while maintaining flexibility and sealing capabilities.
Selecting the appropriate sealing or bonding product depends on several factors:
- Materials being joined: Different substrates require specific adhesive or sealant formulations
- Environmental conditions: Consider temperature, humidity and exposure to weather or chemicals
- Movement requirements: The level of expansion and contraction the joint will experience
- Appearance: Visible or hidden joints may require different finishing options
- Curing time: Project timelines may dictate curing speed requirements
