12 months from date of production

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

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

Non-sag up to 30 mm layer thickness

(1.54 ± 0.1) kg/m² per mm of thickness.

Consumption depends on the roughness and absorbency of the substrate.

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 the Product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

CONCRETE, MASONRY, MORTAR AND STONE

Concrete and mortar must be at least 3 to 6 weeks old. Substrate surfaces must be sound, clean, dry or matt damp. Free from standing water, ice, dirt, oil, grease, coatings, laitance, efflorescence, old surface treatments, all loose particles and any other surface contaminants that could affect adhesion of the adhesive.

STEEL

Surfaces must be clean, dry, free from oil, grease, coatings, rust, scale, all loose particles and any other surface contaminants that could affect adhesion of the adhesive.

WOOD

Substrate surfaces must be sound, clean, dry and free from dirt, oil, grease, coatings, all loose particles and any other surface contaminants that could affect adhesion of the adhesive.

CONCRETE, MASONRY, MORTAR AND STONE

Substrates must be prepared mechanically using suitable abrasive blast cleaning, needle gunning, light scabbling, bush hammering, grinding or other suitable equipment to achieve an open textured gripping surface profile.

STEEL

Surfaces must be prepared mechanically using suitable abrasive blast cleaning, grinding, rotating wire brush or other suitable equipment to achieve a bright metal finish with a surface profile to satisfy the necessary tensile adhesion strength requirement. Avoid dew point conditions before and during application.

WOOD

Surfaces must be prepared by planing, sanding or other suitable equipment.

ALL SUBSTRATES

All dust and loose material must be completely removed from all substrate surfaces before application of the product by vacuum and dust removal equipment.

IMPORTANT

Maintaining workability and handling time. 

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

PRE-BATCHED UNITS

1. Mix part A (resin) briefly using a mixing spindle attached to a slow speed electric mixer (max. 300 rpm).
2. IMPORTANT Mix full units only.Add both parts into a clean and dry container.
3. Mix parts A+B continuously for at least 3 minutes until a uniformly coloured smooth consistency mix has been achieved
4. IMPORTANT Avoid entraining air into the mix by over-mixing. To ensure thorough mixing, pour materials into a clean container and mix again for 1 minute.

IMPORTANT

Damage due to excessive long-term load (creep)

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.

• Ensure that the long-term structural design load is lower than 20-25% of the short-term failure load.
• Consult a structural engineer for calculating the admissible load for the specific application.

1. Apply the mixed adhesive to the prepared surfaces with a spatula, trowel or notched trowel.
2. For optimum adhesion, apply the adhesive to both surfaces that require bonding.
3. For heavy components positioned vertically or overhead, provide temporary support until the Product has fully hardened or cured. Note Hardening and curing depend on ambient temperatures.

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