Sikadur 42 (AU) – 14.6 kg kit

Description

Sikadur 42 (au) is a 3-component pourable solvent free grout based on epoxy resin and selected aggregates.  It cures to form a hardened mortar with excellent adhesion to many substrates.  Sikadur-42 (au)  ease of application makes it ideally suited to high performance grouting in critical site applications.

USES

Sikadur-42(au) has been developed for use in building and civil engineering applications such as:

• Crane rails
• Machine bedding and baseplates
• Holding down bolts
• Starter bars
• Cavity filling
• Bridge bearing pads
• Precast grouting

CHARACTERISTICS AND ADVANTAGES

• Insensitive to moisture during application, cure or whilst in service
• Excellent adhesion to a wide variety of dry and damp substrates such as concrete, stone, fibrous cement, synthetic resins, wood and most metals.
• Applicable at low temperatures down to 5°C.
• High early strength
• High tensile and flexural strength, vibration resistant.
• Supplied in factory proportioned units
• Easy to use
• Unaffected by wide range of chemicals
• Good flow characteristics even in thin layers
• Proven track record

APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY
Mortar and concrete must be older than 28 days (dependent on minimum strength requirements). Verify the substrate strength (concrete, natural stone etc.).
The substrate surface (all types) must be clean, dry and free from contaminants such as dirt, oil, grease, existing surface treatments and coatings etc. Steel substrates must be de-rusted to a standard equivalent to Sa 2.5. The substrate must be sound and all loose particles must be removed. Substrate must be dry or mat damp and free from any standing water, ice etc.

SUBSTRATE PREPARATION

Concrete, mortar, stone:

Substrates must be sound, dry, clean and free from laitance, ice, standing water, grease, oils, old surface treatments or coatings and all loose or friable particles
must be removed to achieve a laitance and contaminant free, open textured surface.

Steel:

Must be cleaned and prepared thoroughly to an acceptable quality standard equivalent to SA 2.5 i.e. by blastcleaning and vacuum. Avoid dew point conditions. Surface and base plate contact area must be clean and sound. For best results, the substrate shall be dry. Remove dust, laitance, oils, grease, curing compounds, impregnations, waxes, foreign particles, coatings, and disintegrated materials by mechanical means, i.e. chipping with a chisel, blastcleaning etc. All anchor pockets or sleeves must be free of water. Apply grout immediately to prevent re-oxidizing / rust formation.

MIXING

Mix components A and B in the component A pail for approx. 30–60 seconds with a paddle attached to a low speed drill (300–450 rpm). Avoid aeration while mixing until the material becomes uniformly blended in colour and viscosity. Place the mixed epoxy into an appropriate mixing vessel. Slowly add the contents of component C (to keep air entrapment at a minimum) dependent on flow requirements (observe the correct mixing ratio) and mix until uniform and homogeneous (approx. 3 min).
Mix only that quantity which can be used within its potlife. Never mix Component A and B without adding component C (as the exothermic reaction between A and B alone generates excess heat) Leave Sikadur®-42 (au) to stand in the normal mixing vessel for 2 – 3 minutes until the majority of entrained air bubbles have dispersed.

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.
