Gorilla Glue (250ml) is a high-strength, long-lasting polyurethane glue, which is suitable for bonding wood, metal, stone, ceramics, glass, foam, leather, and many more materials. The adhesive creates a foaming action when exposed to moisture, filling whilst it sticks, leading to greater coverage. Gorilla Glue is temperature and weather resistant, and once dried it can be sanded, stained, painted, and varnished. It is suitable for indoor and outdoor use.
