Application
Ambient Air Temperature
-15 °C min. / +60 °C max. for hot air welding
+5 °C min. / +60 °C max. for cold welding
Substrate Temperature
-25 °C min. / +60 °C max. for hot air welding
+5 °C min. / +60 °C max. for cold welding
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.
