Sikadur 55 SLV Sikadur: Sika Epoxy 3 Gallon Kit


  • 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.

Sikadur 55 SLV Sikadur: Sika Epoxy 3 Gallon Kit

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. Sikadur 55 SLV is a super low-viscosity, high-strength adhesive formulated specifically for sealing both dry and damp, existing, nondynamic cracks. It conforms to the current ASTM C-881, Types I and II, Grade-1, Class-C* and AASHTO M-235 specifications. Questions? Contact Us.

Substrate must be clean, sound and free of surface moisture. Remove dust, laitance, grease, oils, curing compounds, waxes, impregnations, foreign particles, coatings and disintegrated materials by mechanical means(i.e. shot blasting, sandblasting, etc.). For best results, substrate should be dry. Surfaces prepared by Low Pressure Water Cleaning or High Pressure Water Jetting methods should be allowed to dry for 24 hrs. minimum[at 73 °F (23 °C)].

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

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. Consult Sika Technical Service at 1-800-933-SIKA for additional information.
