Surface Preparation

Substrate Quality

CONCRETE, MASONRY, MORTAR AND STONE

• Concrete and mortar must be at least 28 days old
• Substrates must be sound, clean, dry or matt damp with no standing water
• Substrates must also be free from contamination 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 all contaminants such as dirt, oil, grease, coatings and loose friable material

WOOD

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

Substrate Preparation

Reduced adhesion performance

• Surface contamination such as dust and loose material, including that caused during substrate preparation, can reduce the product's performance
• Thoroughly clean all substrate surfaces before application of the product by vacuum or dust removal equipment

CONCRETE, MASONRY, MORTAR AND STONE

• Suitable techniques for substrate preparation include the following:
  • Abrasive blast cleaning
  • Needle gunning
  • Light scabbling
  • Bush hammering
  • Grinding
  • 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
  • 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

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

Application Notes

MIXING

Maintaining workability and handling time

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

PRE-BATCHED UNITS

• 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)
• 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
• While mixing Parts A + B, gradually add Part C (aggregate)
• IMPORTANT: Do not mix excessively. Mix until a uniform consistency is achieved
• To ensure thorough mixing pour materials into a clean container and mix again for approximately 1 minute

APPLICATION

REPAIR

Preconditions: Prior to application, confirm dew point conditions before and during application.

• On damp prepared concrete substrates, always work the Product well into the substrate
• For vertical or overhead applications use Sikadur 31+ as a primer to improve the bond
• Place temporary formwork as required
• Apply mixed material to the prepared surfaces with a spatula, trowel or by gloved hand
• For repairs greater than 60 mm deep, the Product must be applied in layers
• Scratch the surface of the freshly applied intermediate layer to form a key for the subsequent layer
• Apply successive layers once the previous layer has hardened
• If the time between layers is going to be more than 2 days, blind the wet mortar to excess with quartz sand immediately after application

JOINT FILLING AND CRACK SEALING

• Apply mixed material to the prepared surfaces with a spatula or trowel

CLEANING OF TOOLS

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