Sika Sikadur 55 SLV – 3 Gal Unit
Sikadur 55 SLV is a two-component, 100% solids, super low-viscosity epoxy crack healer and penetrating sealer. Moisture-tolerant and formulated for both dry and damp cracks, it seals cracks as small as 0.002 inches, prolongs the life of concrete, and reduces chloride and water intrusion. With a fast tack-free time of about 6 hours at 73°F, Sikadur 55 SLV minimizes downtime while delivering high bond strength and durability. It conforms to ASTM C-881 and AASHTO M-235 specifications (except gel time) and is designed for interior slabs, elevated decks, parking garages, and other structures subject to foot and tire traffic.
