STORAGE AND SHELF LIFE
GF999 should be stored at or below 27℃ in original unopened containers. It has a shelf life of 12 months from the date of manufacture.
LIMITATIONS
GF999 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℃
