System information

System Structure

Wide range of accessories is available e.g. prefabricated parts, roof drains, scuppers, protection sheets and separation layers.

The following accessories shall be used:

  • Sarnafil® T 66-15 D Sheet for detailing
  • Sarnafil® T Metal Sheet
  • Sarnabar
  • Sarnafil® T Welding Cord
  • Sarnafil® T Prep / Sarnafil® T Wet Task Set
  • Sarnacol® T 660

Application steps

SUBSTRATE QUALITY

The substrate surface must be uniform, smooth and free of any sharp protrusions or burrs, etc.

The supporting layer must be compatible to the membrane, solvent resistant, clean, dry and free of grease and dust. Metal sheets must be degreased with Sarnafil® Cleaner before adhesive is applied.

APPLICATION

Installation works must be carried out only by Sika instructed contractors for roofing.


Installation of some ancillary products, e.g. contact adhesives / cleaners is limited to temperatures above +5 °C. Please observe information given by Product Data Sheets.

 


Special measures may be compulsory for installation below +5 °C ambient temperature due to safety requirements in accordance with national regulations.
