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.

Beware of condensation.

Steel substrate temperature during application must be at least +3 °C above dew point.

The pot life begins when Parts A+B are 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. Another method is to chill Parts A+B before mixing (not below +5 °C).

1.5 kg/m² per mm of thickness, if used as a continuous layer.

0.7 kg/m² –1.0 kg/m² is the quantity normally needed for bonding wet fresh concrete to hardened prepared concrete.

For small anchors or fasteners  (consumption in grams per hole):

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 OR STONE

Concrete and mortar must be at least 28 days old.

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

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

WOOD

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

CERAMICS OR GLASS

IMPORTANT

Siliconised surfaces

The Product will not adhere to substrates with a siliconised surface.

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

ALL SUBSTRATES

1. Completely remove all dust and loose material from all substrate surfaces using vacuum and dust removal equipment. This includes contaminants generated during substrate preparation.

CONCRETE, MASONRY, MORTAR OR STONE

Suitable techniques for substrate preparation include the following:

• Abrasive blast cleaning

• Needle gunning

• Light scabbling

• Bush hammering

• Grinding

1. Prepare the substrate mechanically using a suitable technique.

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

STEEL

Suitable techniques for substrate preparation include the following:

• Abrasive blast cleaning

• Rotating wire brush

• Grinding

1. 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.

WOOD

1. Prepare the substrate by planing, sanding or using other suitable equipment.

CERAMICS OR GLASS

1. Prepare the substrate by sanding or using other suitable equipment.

ALL SUBSTRATES

1. Completely remove all dust and loose material from all substrate surfaces using vacuum and dust removal equipment. This includes contaminants generated during substrate preparation.

When using multiple units during application, do not mix the following unit until the previous unit has been used. This helps to maintain workability.

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 part A to part B.
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, transfer the mixture into a clean container and mix for 1 additional minute.

IMPORTANT

Damage due to unsupported heavy items applied on a vertical surface or overhead

Full adhesion strength is not achieved before the Product has fully cured. Light objects may be bonded without using temporary support during curing. This is dependant on the weight of the object in relation to its size and texture of the surface in contact with the material. If the object is too heavy, it may slip or fall off.

1. Provide temporary support for heavy items until the Product has fully hardened.

BONDING APPLICATIONS

1. IMPORTANT On damp prepared concrete substrates, always apply by brush and work the Product well into the substrate. Apply the mixed the Product to the prepared substrate by brush, roller, spray or trowel ensuring uniform and complete coverage.
2. For optimum adhesion, apply the adhesive to both substrates that require bonding.
3. For bonding wet fresh concrete to hardened prepared concrete, place the concrete whilst the resin layer is still tacky. Note If the product becomes glossy and loses tackiness, apply another coat and proceed to place concrete.

ANCHORING APPLICATIONS

1. For small anchors or fasteners, clean the hole thoroughly with a special round steel brush and with compressed air (minimum pressure 6 bar), starting from the bottom.
2. Once the hole is completely clean and free of any loose particles or dust, pour the Product in the hole, avoiding entrapping air.
3. Insert the anchor or fastener with a rotary motion within the adhesive open time. Note Some of the adhesive must flow out of the hole. 
4. During the resin hardening time, the anchor must not be moved or loaded
