Cracks - Sikadur®-57 Lo-Mod LV

LOW MODULUS, LOW-VISCOSITY, EPOXY RESIN

Sikadur®-57 Lo-Mod LV is a 2-component, 100% solids, moisture-tolerant, epoxy adhesive. It is a low-viscosity, low-modulus adhesive formulated specifically for filling cracks in gravity feed applications.

• Tenacious crack-sealing adhesive.
• Convenient easy mix ratio A:B = 2:1 by volume.
• Advanced low-viscosity, low modulus resin.
• Moisture tolerant

Usage

Sikadur®-57 Lo-Mod LV may only be used by experienced professionals.

• Use neat for gravity feed of cracks in structural concrete, masonry, wood, etc.
• Seal interior slabs and exterior above grade slabs from water, chlorides, and mild chemical attack and to improve wearability.

Advantages

Mixing Ratio

Component ‘A’ : Component ‘B’ = 2:1 by volume

Pot Life

Approximately 20 minutes

Consumption

Coverage

1 gal. (3.8 liters) yields 231 cu. in. (3,785 cm³)

Coverage

Typical coverage is 150-175 sq.ft/gal. (3.7-4.3 sq. m/L) as healer/sealer.

As a primer, coverage is 200-300 sq.ft/gal. (18.6-27.9 sq. m/L)

Coverage varies with porosity and surface profile of substrate. Higher porosity concrete will reduce coverage. For crack healing, follow application instructions and allow to pond over cracks.

Application Steps

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 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.

MIXING

Proportion 1 part Component ‘B’ to 2 parts Component ‘A’ by volume into a clean pail. Mix thoroughly for 3 minutes with Sika Paddle on low-speed (400-600 rpm) drill until uniformly blended. Mix only that quantity that can be used within its pot life.
