General Notes

• Use only recommended concrete, mortar or plastering sands free from clay and organic contamination.
• Use a 50/50 blended 20mm + 10mm stone for concrete aggregate.
• Keep water content to the minimum required for mixing and placing. The more water, the lower the strength.
• Use a standard sized vessel eg., a bucket, to measure all materials.
• Admixtures should only be used according to the manufacturer instructions. Hylime contains an air-entraining agent, additional air entraining agent is not required.
• Quantities estimated are typical industry usage and will vary according to individual use patterns.
