Sika Sikadur-55 SLV – 3 Gallon Unit
Sika Sikadur-55 SLV is a super low-viscosity, two-component epoxy healer/sealer formulated to penetrate and seal non-dynamic cracks in concrete. Designed for both dry and damp conditions, it bonds strongly to substrates and cures quickly to minimize downtime. Its advanced formulation protects against water, chloride, and chemical intrusion, making it ideal for horizontal concrete surfaces such as parking decks, elevated slabs, and industrial floors. Sikadur-55 SLV is traffic-ready in as little as 6 hours and conforms to ASTM C-881 and AASHTO M-235 standards (excluding gel time).
Key Features:
- Ultra-low viscosity for deep penetration into cracks as narrow as 0.002"
- Fast cure – open to traffic in 6 hours at 73°F
- Moisture-tolerant – bonds well to damp concrete
- Improves surface durability and resists water and chemical intrusion
- Conforms to ASTM C-881, Types I & II, Grade 1, Class C
- High bond strength and excellent tensile and flexural properties
Applications:
- Healer/sealer for horizontal concrete surfaces
- Interior and exterior above-grade slabs
- Parking decks, elevated concrete, and loading docks
- Foot and pneumatic tire traffic areas
- Pre-injection preparation for crack repair systems
