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, existing, non-dynamic cracks.
- PRODUCT HIGHLIGHTS
- HOW TO APPLY
• 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
• Allow sufficient time for the substrate to dry after rain or other inclement conditions • Penetration results will vary. Factors that may impede penetration include, but are not limited to, temperature (ambient and material), geometry of crack, concrete porosity, and dirt inside cracks • Do not thin. Addition of solvents will prevent proper cure • Minimum age of concrete is 21-28 days, depending on curing and drying conditions
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.
