STORAGE AND SHELF LIFE
GB1098 should be stored in original unopened containers. It has a shelf life of 12 months from the date of manufacture.
GB1098 should not be applied:
To the materials that bleed oils , plasticizers or solvents, such as impregnated wood, oil-based caulks.
In totally confined spaces as sealant requires atmospheric moisture for cure.
To frost laden or damp surfaces.
For continuous water immersion.
When surface temperature below 4℃ or over 50℃.
To porous substrates such as stone, concrete before confirmation with manufacturer.
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.
