l To the materials that bleed oils , plasticizers or solvents, such as impregnated wood, oil-based caulks

l In totally confined spaces as sealant requires atmospheric moisture for cure

l To frost laden or damp surfaces

l For continuous water immersion

l When surface temperature below 4℃ or over 50℃

 

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

Mask areas adjacent to joints to ensure neat sealant lines. Apply GB 996 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.
