Cracks - Sikadur®-31 Hi-Mod Gel LPL

High-modulus, high-strength, structural, extended pot life, epoxy paste adhesive

Sikadur®-31 Hi-Mod Gel LPL is a 2-component, 100 % solids, moisture-insensitive, high-modulus, high-strength, structural epoxy paste adhesive. It conforms to the current ASTM C-881, Types I and IV, Grade-3, Class-C and AASHTO M-235 specifications.

• Extended pot life
• Moisture-tolerant before, during, and after cure
• High-modulus, high-strength, structural paste adhesive
• Excellent adhesion to concrete, masonry, metals, wood, and most structural materials
• Paste consistency ideal for vertical and overhead applications
• Fast-setting and strength-producing adhesive
• Convenient easy mix ratio A:B = 2:1 by volume

Usage

• Structural bonding of concrete, masonry, metals, wood, etc. to a maximum glue line of 1/8 in. (3mm)
• Seals cracks and around injection ports prior to pressure-injection grouting
• Interior, vertical, and overhead repair of concrete as an epoxy mortar binder
• As a pick-proof sealant around windows, doors, lock-ups etc. inside correctional facilities

Application

Application Information

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

Approximately 120 minutes at 73 °F (23 °C) (gal., L volume)
Approximately 60 minutes at at 90 °F (32 °C) (gal., L volume)

Tack-Free Time: 6-8 hours

Consumption

1 gal. yields 231 cu. in. of epoxy paste adhesive and grout. 1 gal. mixed with 1 gal. by loose volume of oven-dried aggregate yields approximately 346 cu. in. of epoxy mortar.

Application Steps

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 and any other contaminants.

Preparation Work: Concrete - Sandblast or use other approved mechanical methods.
Steel - Blast clean or use other equivalent mechanical means to achieve a white metal finish.

Pre-mix each component. 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 uniform in color. Mix only that quantity that can be used within its pot life.

To prepare an epoxy mortar: Slowly add up to 1 part by loose volume of an oven-dried aggregate to 1 part of the mixed Sikadur®-31 Hi-Mod Gel LPL and mix until uniform in consistency.
