Part A : Part B = 2 : 1 (by weight)

+10 °C min. / +40 °C max.

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

+10 °C min. / +40 °C max.

Cementitious substrates:
Substrate must be dry or matt damp (no standing water).
Brush the adhesive well into the substrate if matt damp.

~30 minutes (100 g mass, +30 °C)

If larger quantities are being mixed the temperature of Sikadur-Combiflex® Adhesive IN will increase due to the chemical reaction, resulting in a reduced pot life.

Sikadur-Combiflex® Adhesive IN may be overcoated with an epoxy coating. If this is required, do not smooth the adhesive with detergent. If waiting time between application of adhesive and overcoating is to be longer than 2 days, the adhesive must be blinded to excess with quartz sand immediately after application.

* The effective consumption can vary depending on site conditions (surface roughness, size of aggregate etc.).

Concrete/masonry/mortar/stone

Concrete and mortar must be at least 3–6 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.

Concrete/masonry/mortar/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 similar to aluminium oxide paper medium grade. Avoid dew point conditions before and during application.

All substrates

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

IMPORTANT

Avoid over mixing to minimise air entrainment.

IMPORTANT

Mix full units only.

Note: Use a spiral paddle in an electric single paddle mixer at a maximum speed of 500 rpm.

1. Mix Part A (resin) for ~60 seconds.
2. Add Part B (hardener) to Part A (resin).
3. Mix Parts A+B continuously for ~2 minutes until a uniformly smooth, coloured mix is achieved.
4. To ensure thorough mixing, pour materials into another clean container and mix again for 1 minute to achieve a smooth and uniform mix.

1. Apply the mixed product by hard brush or trowel.

For detailed application method, please refer Sikadur-Combiflex® SG System data sheet and Sika Method Statement.

Clean all tools and application equipment with Sika® Colma-Cleaner immediately after use. Hardened or cured material can only be removed mechanically.
