Sikadur-32 Hi-Mod LPL may only be used by experienced professionals. Hot weather concrete placements requiring a bonding adhesive.Bond fresh, plastic concrete to hardened concrete and steel. Grout horizontal cracks in structural concrete and wood by gravity feed. Machinery and baseplate grout. Structural adhesive for concrete, masonry, metal, wood, etc.

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 blast cleaning or equivalent mechanical means.
Steel – Should be cleaned and prepared thoroughly by blast cleaning or other equivalent mechanical means.

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 low-speed (400–600 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
32 Hi-Mod LPL is still tacky. If coating becomes glossy and loses tackiness, remove any surface contaminants then recoat with additional 32 Hi-Mod LPL and proceed.

To grout base plates – Add 1 1/2 parts of oven-dried aggregate to 1 part of mixed Sikadur-32 Hi-Mod LPL by volume. Place grout under baseplate. Avoid contact with the underside of the plate. A 1/4 to 3/8 in. (6–10 mm) space should remain between the top of the grout and the bottom of the plate. Maximum thickness of grout per lift is 1.5 in. (38 mm) If multiple lifts are needed, allow preceding layer to cool to touch before applying additional layer. The remaining 1/4 to 3/8 in. (6–10 mm) space should be filled with neat Sikadur-32 Hi-Mod LPL. Pour a sufficient quantity of neat epoxy to allow the level to rise slightly higher than the underside of the bearing plate.
