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, Types I and II, Grade-1, Class-C* and AASHTO M-235 specifications.
* except for gel time
For interior slabs and exterior above-grade slabs.
For elevated horizontal decks, parking garages and other structures exposed to foot and pneumatic tire traffic.
CHARACTERISTICS AND ADVANTAGES
Super low viscosity/low surface tension for excellent penetration into cracks.
Penetrates cracks by gravity down to 0.05 mm in width.
Prolongs life of cracked concrete.
Penetrates/seals surface of slabs from water absorption, chloride-ion intrusion, and chemical attack.
Structurally improves concrete surface.
Can be open to traffic in 6 hours at 23°C.
High bond strength, even in damp cracks.
U.S. Patent No. for ultra-low viscosity healer/sealer to strengthen cracked concrete.
11.3 Litre kit.
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. shotblasting, 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 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 lowspeed (400-600 rpm) drill until uniformly blended. Mix only that quantity which can be used within its pot life.
Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
