All surfaces must be clean, dry, sound and free from dust, oil, old sealant or other contamination. For best results wipe all surfaces with Isopropyl Alcohol (IPA), using a lint free cloth. Adhesion to metals can be further improved by light sanding.
Application: Mask either side of joint to produce a neat finish. Cut tip off cartridge, fit nozzle, load into H.B. Fuller caulking gun and trim nozzle to desired size.
Gently squeeze trigger to dispense and push sealant into joint to ensure complete filling. Within 5 minutes of application, finish surface with wet spatula or other smooth implement. Remove any masking tape before the sealant skins.
