4 System Information Application Details Consumption / Dosage Substrate Preparation The consumption of Sikadur 32, Hi-Mod is ~ 1.42 kg/m 2 per mm of thickness. 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 and any other contaminants. Preparation Work: Concrete - Should be cleaned and prepared to achieve a laitance and contaminant free, open textured surface by blastcleaning or other equivalent mechanical means. Steel - Should be cleaned and prepared thoroughly by blastcleaning. Application. Application Instructions Mixing Application Method / Tools Component A : Component B = 1:1 by volume Pre-mix each component. Proportion equal parts by volume of Component A and Component B into clean pail. Mix thoroughly for 3 minutes with Sika paddle on lowspeed ( rpm) drill until blend is a uniform color. Mix only that quantity that can be applied within its pot life To bond fresh concrete to hardened concrete - Apply by brush, roller, broom or spray. Place fresh concrete while Sikadur 32, Hi-Mod, is still tacky. If coating becomes glossy and loses tackiness, remove any surface contaminants then recoat with additional Sikadur 32 Hi-Mod, and proceed. To grout baseplates - Add up to 1 1/2 parts of oven-dried aggregate to 1 part of mixed Sikadur 32, Hi-Mod, by volume. Place grout under baseplate. Avoid contact with the underside of the plate. A (6 to 10 mm) space should remain between the top of the grout and the bottom of the plate. Maximum thickness of grout per lift is (38 mm) If multiple lifts are needed, allow preceding layer to cool to touch before applying additional layer. The remaining (6 to 10 mm) space should be filled with neat Sikadur 32 Hi-Mod. Pour a sufficient quantity of neat epoxy to allow the level to rise slightly higher than the underside of the bearing plate. To gravity feed cracks - Pour neat material into vee-notched crack. Continue placement until completely filled. Seal underside of slab prior to filling if cracks reflect through 4 4/5

5 Cleaning of Tools Notes on Application / Limitations Value Base Clean all tools and application equipment with Sika Colma Cleaner immediately after use. Hardened / cured material can only be mechanically removed. Minimum substrate and ambient temperature (4 C). For spray applications, consult Technical Service Use only oven-dry aggregate (Sikadur aggregates). Material is a vapor barrier after cure. Do not apply over wet, glistening surface (Standing water). Not an aesthetic product. Color may alter due to variations in lighting and/or UV exposure. All technical data stated in this Product Data Sheet are based on laboratory tests. Actual measured data may vary due to circumstances beyond our control.
