Technical Information
Application
Application Information
Mixing RatioComponent ‘A’ : Component ‘B’ = 1:1 by volume
Pot LifeApproximately 60 minutes at 73 °F (500 gram mass)
Cure TimeTack-Free Time: 1.5-2.5 hours at 30 mils. thick
Consumption
Coverage1 gal. yields 231 cu. in. (3,785 cm3) of epoxy paste adhesive. 1 gal. (3.8 L) mixed with 1 gal. (3.8 L) by loose volume of oven-dried aggregate yields approximately 346 cu. in. (5,670 cm3) of epoxy mortar.
Application Steps
SUBSTRATE PREPARATIONSurface must be clean and sound. It may be dry or damp, but free of standing water. Remove dust, laitance, grease, curing compounds, impregnations, waxes, and any other contaminants.
Preparation Work: Concrete - Should be cleaned and prepared to achieve a laitance and contaminant free, open textured surface by blast cleaning or equivalent mechanical means.
Steel - Should be cleaned and prepared thoroughly by blast cleaning or other equivalent mechanical means.
MIXINGPre-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.
