To ensure proper mixing, use a mechanically-powered mixer or a heavy-duty, slow-speed drill fitted with a suitable paddle. Stir the base (component A) and the hardener (component B) individually to disperse any settling material.
Pour the entire contents of the base and hardener into a container of a suitable size then mix (mechanically) for 2 minutes. Add the Filler (component C) and mix for 3 more minutes until a uniform and lump-free consistency is achieved.
