Mixing

Pre-mix each component. Proportion 1 part Component ‘B’ to 1 part Component ‘A’ by volume into a clean pail or appropriately sized mixing container. Mix thoroughly for 3 minutes with Sika paddle on low-speed (400–600 rpm) drill until uniform in color. Mix only that quantity which can be used within its pot life. Prior to mixing, material should be conditioned to 65–85 °F (18–29 °C). To prepare an epoxy mortar, slowly add up to 1 part, by loose volume of an oven dried aggregate, to 1 part of the mixed Sikadur 31 Hi-Mod Gel, and mix until uniform in consistency.
