Application

Application Information

Ambient Air Temperature

Ambient temperature:     -20 °C min. / +60 °C max.

Substrate Temperature

Substrate temperature:   -30 °C min. / +60 °C max.

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 Sarna Cleaner before adhesive is applied.

APPLICATION

Installation works must be carried out only by Registered Sika Sarnafil Roofing Contractors.

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.
