- APPLICATIONSAnti-CRAK® HP is designed to provide enhanced crack control and toughness to commercial and residential slabs, and garage floors. Additionally, Anti-CRAK® HP is also broadly used in manufactured concrete products, dry mix formulations, stucco, render, UHPC, and other concrete applications.
TOUGHER
• Superior finishability
• Neutral buoyancy and uniform dispersion
• No rust, no staining
• Multi-filament strand mineral fiber with natural affinity to cementitious materials

Packaging & Storage
Anti-CRAK® HP 12: Packed in 600g and 1lb paper bags (water dispersible), and plastic bags (6 kg)Anti-CRAK® HP 18: Packed in 7 kg plastic bags
Anti-CRAK® HP 24: Packed in 5 kg plastic bags
Anti-CRAK® HP should be stored away from heat and moisture, and must stay in its original packaging. Optimum conditions are temperature between 15°C and 35°C (59ºF to 95ºF) and humidity between 35% and 65%. If the product is stored at lower temperatures, it is advisable to condition it in the workshop for at least 24 hours before use, to prevent condensation.
Quality Standards
Anti-CRAK® HP is manufactured under a quality management system approved to ISO 9001.Anti-CRAK® HP is not classified as dangerous by the Regulation 1272/2008/EC. For more information, please refer to our Safe Use Instruction Sheet.
