The Product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +30 °C. Always refer to the packaging.

Refer to the current Safety Data Sheet for information on safe handling and storage.

Depending on the project, the amount of Part C can be increased as follows:

For further information contact Sika® Technical Services.

Beware of condensation. Substrate temperature during application must be at least +3 °C above dew point.

Pot life begins when all parts have been mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the pot life.

To obtain longer workability at high temperatures, the mixed adhesive may be divided into smaller quantities. Alternatively, if the application temperature is above +20 °C, chill parts A+B before mixing.

~2.3 kg/m² per mm. 

NOTE: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

Each 20.4kg kit will yield ~8.85 litres of mixed material. 

IMPORTANT

Reduced adhesion due to surface contamination

Surface contaminants such as dust and loose material, including the contaminants generated during substrate preparation, can reduce the Product's performance.

• Before applying the Product, clean thoroughly all substrate surfaces using vacuum or dust removal equipment.

IMPORTANT

Damage to the substrate or equipment due to vibration

For optimum results when grouting critical equipment, follow the surface preparation requirements of the latest edition of the American Petroleum Institute Recommended Practice 686 “Machinery Installation and Installation Design”, Chapter 5.

CONCRETE

Suitable techniques for substrate preparation include the following:

• Abrasive blast cleaning

• High-pressure water blasting

• Needle gunning

• Scabbling

• Bush hammering

• Grinding

Preconditions

Concrete must be at least 28 days old.

1. Prepare the substrate mechanically using a suitable technique.
2. Remove any debris from pockets or holes for structural fixings.

The substrate has an open-textured, gripping surface profile.

Substrates must be sound, clean, dry or matt damp but free of standing water. Substrates must be free of contaminants such as ice, dirt, oil, grease, coatings, laitance, efflorescence, surface treatments and loose friable material.

STEEL

Suitable techniques for substrate preparation include the following:

• Abrasive blast cleaning

• High-pressure water-blasting

• Grinding

• Prepare the substrate mechanically using a suitable technique.

The substrate has a bright metal finish with a surface profile to satisfy the necessary tensile adhesion strength requirement.

Surfaces must be sound, clean, dry and free of contaminants such as dirt, oil, grease, coatings and loose friable material.

SHUTTER FORMWORK

Preconditions

Where formwork is to be used, all formwork must be of adequate strength, treated with release agent and sealed to prevent leakage.

• Prepare the formwork to maintain a minimum 100 mm grout head to assist with placement.

NOTE: A grout box equipped with an inclined trough attached to the formwork will also improve the grout flow and reduce air voids.

IMPORTANT

Poor workability and unfavourable handling time due to wrong mixing

• When using multiple units during application, do not mix the following unit until the previous unit has been used.

PRE-BATCHED UNITS

1. IMPORTANT: Mix full units only. Prior to mixing all parts, mix Part A (resin) briefly using a mixing spindle attached to a slow speed electric mixer (maximum 300 rpm).
2. Add Part A to Part B (hardener) and mix Parts A+B continuously for at least 3 minutes until a uniformly coloured smooth consistency mix has been achieved.
3. While mixing Parts A + B, gradually add Part C (aggregate).
4. IMPORTANT: Do not mix excessivley. Mix until a uniform mix is achieved.

BULK PACKAGING

1. Prior to mixing all parts, mix Part A (resin) and Part B (hardener) briefly using a mixing spindle attached to a slow speed electric mixer (maximum 300 rpm).
2. Add the parts in the correct proportions into a suitable mixing container.
3. Mix Parts A+B continuously for at least 3 minutes until a uniformly coloured smooth consistency mix has been achieved.
4. While mixing Parts A + B, gradually add the correct proportion of Part C (aggregate).
5. IMPORTANT: Do not mix excessivley. Mix until a uniform mix is achieved.

IMPORTANT

Damage due to excessive long-term load

Sikadur® resins are formulated to have low creep under long-term load. However, due to the creep behaviour of all polymer materials under load, the long-term structural design load must account for creep.

1. Ensure that the long-term structural design load is lower than ¼ to ⅕ of the short-term failure load.
2. Consult a competent Structural Engineer for calculating the admissible load for the specific application.

GROUTING

1. IMPORTANT: Maintain a 100 mm grout head to avoid trapping air. Pour the mixed grout into the prepared formwork ensuring continuous grout flow during the complete grouting operation.
2. Where formwork has been used for grouting base plates and machine bases, place sufficient epoxy grout in the formwork to rise slightly above the underside (3 mm) of the grouted base.

FLOWABLE REPAIR

• Immediately after mixing, pour the mixed material into the formwork or repair area.
• Ensure a continuous flow.

ADDITIONAL LAYERS

• Apply additional layers in successive pours once each layer has cooled and hardened sufficiently.
• NOTE: The last layer of a multiple pour must be at least 50 mm.

Clean all tools and application equipment with Sika® Thinner C immediately after use. Hardened material can only be removed mechanically.
