Sikadur-30
Application
Important
- When applied to mat moisture concrete, brush Sikadur-30 well into substrate
- Max. layer thickness 30 mm
- Use low speed mixer (max. 500 rpm) to entrain as little air as possible
Substrate
Concrete, stone, brickwork:
- Clean, free from oil and grease, dry, no loose particles or laitance
- Concrete age, depending on climate, 3 to 6 weeks
- Preparation: Sandblasting, high-pressure water jetting, grinding
- Max. substrate moisture: 10%
- If the concrete surface has large uneven sections or holes after preparation, these must
first be filled with Sikadur-41 or a mixture of Sikadur-30 and quartz sand Sikadur-501
(mixing ratio 1 : 1 by weight).
Timber:
- Clean, free from oil and grease
- Sandblast or grind well
Structural steel 37, V2A-Steel (WN 1.4 301):
- Free from grease and oil, free from rust, scale and rolling „skin“
- Preparation: Sandblast SA 2.5
- Beware of condensation (dew point), application only at > 3°C above dew point
- If the cleaned steel is not bonded immediately, the surface must be given one coat of
Sikagard-63N to protect it from further corrosion.
Epoxy:
- Free from oil and grease
- Grind well using coarse abrasive
Mixing
Predosed pack:
Stir the material well in the containers. Add component B to component A. Mix with an electric low speed hand mixer (max. 500 rpm) for about 3 minutes to uniform appearance.
Entrain as little air as possible.
Bulk packing, not predosed:
Stir the material well in the containers. Add the components in the correct proportion into
suitable mixing vessel and stir correctly using electric low speed mixer.
The pot life begins when the resin and hardener 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
portions. Another method is to chill components A and B before mixing them.
Application
The well-mixed Sikadur-30 is applied with a spatula, trowel or float.
When landing steel plates or Sika CarboDur strips Sikadur-30 ist applied to the strips in
„pitched-roof“ shape. Within the open time the Sika Carbodur strips or the steel plates must
be fixed in their final position.
Steel plates are being fixed to the concrete substrate with the aid of specially prepared
supporting scaffolding. Since at normal ambient temperature Sikadur-30 cures very fast, the
scaffolding can be removed within 2-3 days (please refer to the curing times at various
temperatures).
Sika Carbodur strips are firmly pressed to the substrate by hand with the aid of a rubber
roller. It is essential that the Sika Carbodur strip is evenly pressed to the substrate until the
Sikadur-30 adhesive is squeezed out on both sides of the strips.
As a final check the Sika CarboDur strips are being probed for voids with a coin. It is recommended to check the adhesive with regard to strength development ba producing cubes at
site and to test them for compressive and flexural strength.
Cleaning
Clean tools immediately with Colma cleaner. Wash hands and skin thoroughly in warm soap
water.
When uncured, Sikadur-30 components A+B, are water-pollutants and should not be
discharged into drains, waterways or the ground.
Colma cleaner and Sikadur-30 residues must always be disposed of in accordance with the
regulations.
Cured material can only be removed mechanically.
