APPLICATION

Before use, open cartridge by cutting off plastic nipple above screw thread with a sharp knife. Attach nozzle to cartridge and cut it slantwise (opening at least Ø 5 mm).

Apply adhesive evenly in dots or lines every 20-40 cm, depending on weight of material. Always apply adhesive in corners and along edges. Join parts immediately with a sliding movement and press or tap firmly. Adjustments can still be made. In case of materials under tension or two non-porous materials, apply the 'Power Bonding Method': fix material, press and pull off immediately. Let dry for 5 minutes, fix in the same place and press or tap firmly. Adjustments cannot be made. If necessary, secure or support heavy materials.

SURFACE PREPARATION
Clean all grease, dirty, water, clunky sealant from surface, accessories and protective coatings and any pollutant left inside joints and sunken parts. For best results wipe all surfaces with GNS cleaner, methylated spirits, use a lint free cloth, then wipe again with a dry lint free cloth. Detergent or soap water treatments are not recommended.
COMPATIBILITY TESTING
Incompatibility of glazing materials can lead to sealant discoloration and/ or loss of adhesion. To help protect against these problems and to ensure compatibility, GNS will also test and provide information on the compatibility of accessory materials (gaskets, spacers, etc.) and other GNS silicone sealants.




Caution
Uncured silicone can irritate eyes and skin. If contact is made with eyes, flush with water for 15 minutes and seek medical advice. Use in well ventilated area and keep out of reach for children.
