SUBSTRATE QUALITY

The substrate surface must be uniform, smooth and free of any sharp protrusions or burrs, etc.
Sikaplan® SGmA-15 must be separated from any incompatible substrates by an effective separation layer to prevent accelerated ageing.

APPLICATION

Installation works must be carried out only by Sika instructed contractors for roofing.
Installation of some ancillary products, e.g. contact adhesives/thinners is limited to temperatures above +5 °C. Please refer to the respective Product Data Sheets. Special measures may be compulsory for installation below +5 °C ambient temperature due to safety requirements in accordance with national regulations.
