Overview


Cracks - Sikadur®-35 Hi-Mod LV

High modulus, low viscosity, high strength epoxy grouting/sealing/binder adhesive

Sikadur®-35 Hi-Mod LV is a 2-component, 100 % solids, moisture-tolerant, low-viscosity, high-strength, multipurpose, epoxy resin adhesive. It conforms to the current ASTM C-881, Types I, II, and IV, Grade-1, Class C* and AASHTO M-235 specifications. *except for gel time

  • Super low viscosity.
  • Convenient easy mix ratio A:B = 2:1 by volume.
  • Unique, high-strength, structural adhesive for “can’t dry” surfaces.
  • Deep penetrating and tenacious bonding of cracks in structural concrete.
  • High-early-strength developing adhesive.
  • Excellent chemical resistance in flooring systems.

Usage

  • Pressure-injection of cracks in structural concrete, masonry, wood, etc.
  • Gravity-feed of cracks in horizontal concrete and masonry.
  • Epoxy resin binder for epoxy mortar patching and overlay of interior, horizontal surfaces.
  • Seal interior slabs and exterior above-grade slabs from water, chlorides, and mild chemical attack; also
    improves wearability.

Advantages

  • Super low viscosity.
  • Convenient easy mix ratio A:B = 2:1 by volume.
  • Unique, high-strength, structural adhesive for “can’t dry” surfaces.
  • Deep penetrating and tenacious bonding of cracks in structural concrete.
  • High-early-strength developing adhesive.
  • Excellent chemical resistance in flooring systems.

Technical Information

Application

Application Information

Mixing Ratio

Component "A": Component "B" = 2:1 by volume.

Pot Life

Approx. 25 minutes (mass of 60 grams)

Consumption

Coverage

1 gal. yields 231 in3 of adhesive and grout. 1 gal. of adhesive, when mixed with 5 gal. by loose volume of oven-dried aggregate, yields approximately 808.5 in3 of epoxy mortar.

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, foreign particles and disintegrated materials.
Concrete - Blast clean, shot blast or use other approved mechanical means to provide an open roughened texture.
Steel - Should be cleaned and prepared thoroughly by blast cleaning.

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. To prepare an epoxy mortar, slowly add 4-5 parts by loose volume of an ovendried aggregate to 1 part of the mixed Sikadur®-35 Hi-Mod LV and mix until uniform in consistency.
