Application
Mixing Ratio
Component ‘A’:Component ‘B’ = 1:1 by volume
Pot Life
Approximately 45 minutes. (200 gram mass)
SUBSTRATE PREPARATION
Surface must be clean and sound. It may be dry or damp, but free of standing water. Remove dust, laitance, grease, curing compounds, impregnations, waxes, foreign particles, disintegrated materials.
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 other equivalent mechanical means to a shiny metal finish.
MIXING
Pre-mix each component. Proportion equal quantities by volume of Component ‘A’ and Component ‘B’ into a clean pail. Mix thoroughly for 3 minutes with a Sika paddle on a low-speed (400–600 rpm) drill until uniform in color. Slowly add up to 1 part by loose volume of an oven-dried aggregate to 1 part of mixed Sikadur®-23 Lo-Mod Gel, and mix until uniform in consistency. Mix only that quantity that can be used within its pot life.
