Sikadur 32

Sikadur 32

Technical Data (.pdf)
MSDS Part A (.pdf)
MSDS Part B (.pdf)

Sikadur 32, Hi-Mod, is a multi-purpose, 2-component, 100% solids, moisture-tolerant structural epoxy adhesive. It conforms to the current ASTM C-881 and AASHTOM-235 specifications.

Uses
• Bond fresh, plastic concrete to hardened concrete and steel.
• Grout horizontal cracks in structural concrete and wood by gravity feed.
• Machinery and ‘robotic’ base-plate grout.
• Structural adhesive for concrete, masonry, metal, wood, etc.

Advantages
• Super-strength bonding/grouting adhesive.
• Tolerant to moisture before, during and after cure.
• Excellent adhesion to most structural materials.
• Convenient easy-to-mix ratio A:B = 1:1 by volume.
• Easy-to-use for bonding/grouting applications.
• Fast initial set; rapid gain to ultimate strengths.
• USDA-certified for use in food plants. • Effective vapor barrier after cure.

Application
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 1/4 to 3/8 in. (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 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 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.

Coverage
• Bonding Adhesive - 1 gal. covers approximately 80 sq. ft. on smooth surface.
• Base Plate Grout - 1 gal. mixed with 1.5 parts oven-dried aggregate by loose volume yields approximately 420 cu. in. of grout.
• Anchoring grout - 1 gal. yields 231 cu. in. of grout.

Sikadur 55 SLV

Sikadur 55

Sikadur 55 SLV is a 2-component, 100% solids, moisture-tolerant, epoxy crack healer / penetrating sealer, having a fast tack-free time to minimize downtime. It is a super low-viscosity, high-strength adhesive formulated specifically for sealing both dry and damp cracks. It conforms to the current ASTM C-881 and AASHTO M-235 specifications.

Uses
• Sikadur® 55 SLV seals cracked concrete.
• For interior slabs and exterior above-grade slabs.
• For elevated horizontal decks, parking garages and other structures exposed to foot and pneumatic tire traffic.

Advantages
• Super low viscosity/low surface tension for excellent penetration into existing cracks.
• Seals existing cracks by gravity down to 2 mils (0.002” / 0.05 mm) in width.
• Prolongs life of cracked concrete.
• Penetrates and seals surface from water absorption, chloride-ion intrusion, and chemical attack (patent pending technology).
• Improves concrete surface by reducing water and chloride intrusion.
• Can be open to traffic in 6 hours at 73°F (23°C).
• High bond strength, even in damp cracks.
• U.S. Patent No. (pending) for ultra low viscosity healer/sealer to strengthen cracked concrete.

Application
To gravity feed cracks: Sikadur 55 SLV is applied to horizontal surfaces by flat squeegee or broom. Spread material over area and allow to pond over cracks. Let material penetrate into cracks and substrate. Remove excess epoxy with roller leaving no visible surface film. For cracks greater than 1/8 in. (3 mm) wide, fill crack with oven-dried sand before applying Sikadur® 55 SLV. Seal cracks from underside, when accessible, to prevent leakage. A second treatment may be required on very porous substrates. Apply second treatment before broadcasting. After treatment, wait a minimum of 20-30 minutes at 73°F (23°C) before broadcasting sand. Cover with broadcast of an oven-dried 20/40 silica sand or similar sand. Distribute evenly over the surface to excess at a rate of 30-40 lbs./100 sq. ft.. Allow to cure 6 hours minimum at 73°F (23°C). Remove any loose sand and open to traffic once epoxy has cured.
To pressure inject cracks: Use automated injection equipment. Set appropriate injection ports. Seal ports and cracks with Sikadur® 31, Hi-Mod Gel, Sikadur® Injection Gel or Sikadur® AnchorFix 2/Sikadur® AnchorFix 500. When the epoxy adhesive has cured, inject Sikadur® 55 SLV with steady pressure.
Mock ups to ascertain penetration on job site conditions is strongly recommended. Actual penetration should be verified by core testing.

Coverage 1 gal. (3.8 liters) yields 231 cu. in. (3,785 cm3). Typical coverage is 150-175 square feet per gal. (3.7-4.3 m2/L) for surface sealing. 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.
