Sikadur®-53 CA
EPOXY RESIN-BASED STRUCTURAL GROUT DESIGNED FOR INJECTION, ANCHORING AND
SEATING APPLICATIONS
Sikadur®-53 CA is a two-component structural grout based on epoxy resin, designed for injection, anchoring, and seating applications and for use at temperatures between 5 and 30 °C.
- Applicable for gravity feeding or pressure injection of cracks widths ranging from 0.5 to 30mm (0.02 to 1.18 in)
- Applicable to a maximum thickness of 30 mm (per layer) for base plate/seating applications
- Application temperature between 5 and 30 °C
- Hardens without shrinkage
- Hardens even in damp conditions
- Barrier against moisture and oxygen
- Prevents the entry of water and the infiltration of substances causing corrosion of the reinforcement in the structures
- Good adhesion on concrete, steel, masonry elements, stone
- Good adhesion on cement-based substrates immersed in salt water
- Displaces water from the cracks and voids during filling
- Good mechanical strength even after hardening underwater
- Injectable with a single piston pump or bulk injection equipment
Usage
- Injection of voids and cracks by gravity or under pressure, including in wet or submerged environments
- Grouting of anchors, posts, connectors for mixed wood or concrete floors, etc.
- Seating of support plates, machine bases, metal rail support saddles (track work, crane tracks), metal profiles, etc.
- Filling of cavities, voids, etc., including in a submerged environment (by displacement of the water in place when filling the void with Sikadur®-53 CA)

| 24.5 kg | 30 minutes |
Note: Pot life begins when the two components are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the pot life. For longer pot life at high temperatures, divide the mixed product into several portions. Another method is to cool components A and B before mixing (not below 5 °C / 41 °F).
SUBSTRATE PREPARATION
Concrete / masonry / mortar / stone
Check the resistance of the substrate. The surface after preparation must be clean, dry and free of all contaminants (impurities, oil, grease, coating or existing surface treatment) that could alter the adhesion of the product to the substrate. The substrate must be prepared mechanically (sandblasting, shot-blasting or other appropriate mechanical means) until an open surface texture is obtained. For concrete surface preparation, a CSP 3-4 as per ICRI is required.
Steel
All steel contact surfaces must be dry, clean and stable. Remove all existing treatments such as coatings, sealers, wax, and contaminants i.e. dirt, dust, grease, oils, and foreign matter, which will interfere with the adhesion of Sikadur®-53 CA. Prepare steel substrates by appropriate mechanical means, such as abrasive blast-cleaning in order to achieve clean white metal profile equivalent to SSPC-SP10, Near White Metal, 2 to 4 mil anchor profile, and install grout before oxidation of the steel occurs.
MIXING
Pre-mix each component separately. Empty component B into the component A pail. Mix the combined components for at least three (3) minutes, using a low-speed drill (300 - 450 rpm) to minimize entrapping air. Use an Exomixer® or Jiffy® type mixing paddle (recommended model) suited to the volume of the mixing container. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once, to ensure complete mixing. When completely mixed, Sikadur®-53 should be uniform in colour and consistency.
For application under water, let the product stand for 15 minutes (at 20 °C / 68 °F) after mixing components A and B for the product to start a pre-reaction, to obtain an optimal adhesion on the substrate.
Mix only the number of kits that can be installed during the pot-life.
CLEAN UP
Clean all tools and equipment with Sika® Epoxy Cleaner. Once hardened, product can only be removed mechanically.
