Adheseal PU15

Uses:

• Perimeter sealing of windows and curtain walls
• Masonry joints
• Expansion joints in precast and tilt-up panels
• Tile joints in walls and floors
• Metal cladding
• General construction sealing
• Adhesive for lightweight components

Benefits:

• Accommodates joint movement without cracking or losing adhesion
• Forms a weather-resistant and durable seal
• Reduces noise and vibration transmission
• Provides a flexible bond for various materials
• Contributes to a healthier and more sustainable building environment

Application Guide

1. Joint Preparation:
   • Ensure substrates are sound, clean, and free from contamination.
   • Clean with Adheseal cleaning solvent if necessary.
2. Priming:
   • Priming is not usually required but is recommended for floor joints or suspect surfaces.
   • Adhesion testing is recommended for uncertain surfaces.
   • If priming is required, use the appropriate primer and allow it to dry (see Primer Selection Chart).
3. Backer Rod:
   • Use Adhefoam open cell backer rod where needed.
   • Closed cell backer rod can be used, but avoid damaging the outer skin to prevent gassing.
   • If the joint is too shallow for backer rod, use a bond breaker tape to prevent three-sided adhesion.
4. Application:
   • Fill the joint completely, avoiding air entrapment.
   • Tool the sealant within 10 minutes (depending on temperature and humidity).

Limitations

• Not suitable for long-term water immersion.
• Not suitable for internal swimming pool applications.
