Application steps

SUBSTRATE QUALITY

The substrate surface must be uniform, smooth and free of any sharp protrusions or burrs, etc.
The Polyester fleece laminated to Sikaplan® SGK-15 underside separates sufficiently from any incompatible substrate. It prevents from direct contact to bitumen or plastic material, e.g. expanded polystyrene (EPS), extruded polystyrene (XPS), polyurethane (PUR), polyisocyanurate (PIR) or phenolic foam (PF) for compatibility in the built-up.

APPLICATION

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