A strong polyurethane glue that has a fast initial grab time and will expand slightly to increase bite strength. For interior and exterior use. Fast Grab 5 minute has an initial grab time of 5 to 10 minutes and a firm bond in 4 hours. Full cure will require 24 hours. After setting, the bond is very stable resisting 'creep', immersion in salt water and exposure to the elements. Use on damp wood, hardwoods, concrete, metal, brick, tarmac, MDF, polystyrene, cork and fibreglass.
