APPLICATION
Cut seal on top of cartridge. Screw on nozzle and cut the nozzle at 45°angle to the desired shape and size. For better appearance, cover outside of joint areas with masking tapes before application. Tool immediately after sealant application and remove masking tape before sealant skins
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 or acetone, 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.
