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
  • Sarnacol® T-660
  • Sarnafil® T Clean

Compatibility

Sikaplan® TB-12 may be installed on all thermal insulations and levelling layers suitable for roofing. No additional separation layer is required.
Sikaplan® TB-12 is suitable for installation directly on top of existing, carefully cleaned, level bituminous roofing, e.g. re-roofing over old flat roofs.
Colour changes in membrane surface may occur in case of direct contact with bitumen.
In case of existing roof build-up needs to be removed, Sikaplan® TB-12 can be adhered directly on to the bituminous vapour control layer for partitioning and protection of the day work.

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 Solvent T 660 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.
