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 GUIBAO 557 in a continuous operation using dispensing guns. Before a skin forms, tool the sealant with light pressure to spread the sealant against the joint surfaces. Remove masking tape as soon as the bead is tooled.

Limitations
GUIBAO557 should not be applied:
  1. For structural glazing
  2. For weather seal for curtain walls
  3. For underground joints
  4. For high-movement joints
  5. For the materials that bleed oils, plasticizers or solvents, such as impregnated wood, unvulcanized resin
  6. In totally confined spaces as sealant requires atmospheric moisture for cure
  7. For frost-laden or damp surfaces
  8. For continuous water immersion
  9. When surface temperature below 4ºC or over 50ºC
Safety Information
  1. GUIBAO 557 is a chemical product, not edible, no implantation into body and should be kept away from children.
