Extramite (Cascamite) is specially formulated for exterior joinery exposed to the weather. The powder system enables extremely good gap filling properties ensuring water does not enter the joint and produces the strongest bond. It attains bond strength very quickly, enabling it to be used for load bearing and laminating. Use internally and externally where high bond strength, gap filling or water resistance is required. Available in 500g, 1.5Kg, 3Kg and 6kg.
