• Sika® Air Pak is only suitable for use in concrete with <50mm slump, i.e. semi-dry/extruded concretes, subject to trials to ensure mixing efficacy.
• Due to the significant number of constituent, mix design, manufacture and placing related factors outside Sika’s control, bubble spacing determination should be carried out by the concrete producer to ensure compliance with BS EN 934-2. Bubble spacing should be completed using the specific concrete constituents/admixture combinations.
• Overdosing may cause an excessive increase in air-entrainment that will lower the compressive strength.

• Sika® Air Pak should not be added to the gauging water.
• When added directly to a truck mixer, the mixer shall rotate its drums at maximum revolutions for at least 1 minute per m³ concrete and a minimum of 5 minutes to achieve a uniform mix.
