Compatibility
Sarnafil® TG 76-15 Felt may be installed on all thermal insulations and levelling layers suitable for roofing. No additional separation layer is required.
Sarnafil® TG 76-15 Felt is suitable for installation directly on top of existing, carefully cleaned, level bituminous roofing, e.g. re-roofing over old flat roofs.
Sarnacol®-2142 S single-component PUR adhesive is designed for adhering feltbacked Sarnafil® TG 76-15 Felt to standard insulations and substrates. Adhering Sarnafil® TG 76-15 Felt by means of Sarnacol®-2142 S is particularly suitable for reroofing over old bitumen waterproofing. (Not suitable for re-roofing over synthetic, rubber or ECB roofing).

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 and free of oil and grease. Cut open any blisters in the old waterproofing and repair.
The safety of the existing roof assembly in terms of wind uplift must be ensured. Any insufficiently secured sections or components (Example: chippings, slating etc.) must be removed to provide a smooth surface.
The curing of Sarnacol®-2142 S requires moisture. The base layer may therefore be slightly moist (no puddles). If the relative humidity is below 35 % moisten the adhesive after it has been applied.
APPLICATION
Installation works to be carried out only by Sika instructed contractors for roofing.
Installation of some ancillary products, example 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.
