Sikadur®-42 MY
Pourable epoxy grout
Sikadur®-42 MY is a 3 parts pourable grout, based on a combination of epoxy resins and specially graded aggregates. After mixing, it forms a flowable mortar, suitable for grouting and filling.
- Fast, accurate fixing
- Rapid strength gain
- Shrinkage free hardening
- High mechanical strength
- Hardens even at high humidity
- High resistance against abrasion impact and vibration
- Can be applied on dry and damp surfaces (no standing water)
- Good flow characteristics even in thin layers
Usage
- Self-levelling, flowable epoxy mortar on concrete, stone, mortar, steel, aluminium, asbestos, cement, wood, polyester and epoxy
- Structural bonding of starter bars, anchors, support, braces and tie bars
- Grouting of crash barrier posts, bearing plates, machine bases, mechanical bridge joints and bridge bearings
- Tie-less rail grouting of crane rails, in tunnels and on bridges

SUBSTRATE PREPARATION
Substrate and contact area of base plate, etc. must be clean and sound. Remove laitance, oils and grease by sandblasting or bush hammering. Vacuum clean. Sandblast bottom of base plates and solvent wipe clean.
Remove defective areas and patch with Sikadur®-41 CF Normal (refer to Product Data Sheet for details). Allow to cure.
Formwork
Due to the flowable consistency of Sikadur®-42 MY, seal the forms to prevent seepage. Apply wax to forms or use other bond breaking materials to prevent adhesion of epoxy grout.
MIXING
Mix all of part B (hardener) with all of part A (resin) for at least 2 minutes with a low speed electric drill (500 rpm) until a smooth consistency and uniform colour is achieved. Then add all of part C (aggregates) and continue mixing until a homogeneous mix is obtained.
Use immediately.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened or cured material can only be mechanically removed.
