HOW TO USE


Surface Preparation

Clean all joints removing all foreign matter and contaminants such as oil, grease dust, water, frost, old sealants, surface dirt, or glazing compounds and protective coatings.


Application Method

Install back-up materials or joint fillers, setting blocks, spacer shims, and tapes. Mask areas adjacent to joints to ensure neat sealant lines. Primer is generally not required for non-porous surfaces, but may be necessary for optimal seal performance of certain porous surfaces. So adhesion test is always recommended.


Apply GB 1098 in a continuous operation using dispensing guns. Before a skin forms, tool the sealant with light pressure to spread the sealant against the backing materials and joint surfaces. Remove masking tape as soon as the bead is tooled.
