This should be done by the use of Concure curing membrane, continuous application of water and/or wet hessian. Cleaning Conbextra Deep Pour should be removed from tools and equipment with clean water immediately after use. Cured material can be removed mechanically. Limitations Low temperature working When the air or contact surface temperatures are 5°C or below on a falling thermometer, warm water (30-40°C) is recommended to accelerate strength development. For ambient temperatures below 10°C the grout consistency should be flowable and the formwork should be maintained in place for at least 36 hours. Normal precautions for winter working with cementitious materials should then be adopted. High temperature working At ambient temperatures above 35°C the mixed grout should be stored in the shade. Cool water (below 20°C) should be used for mixing the grout. Note: long narrow grouting sections should be avoided where possible and pours arranged to achieve a length : minimum thickness ratio of not more than 20 : 1. INDEX 130 Estimating Supply 201070 - Conbextra Deep Pour is supplied in 20 kg moisture resistant bags. Yield Allowance should be made for wastage when estimating quantities required. The approximate yields are: Flowable Consistency litres / bag kg / m³ No. bags / m³ Yield 10.0 2200 100 Storage Conbextra Deep Pour has a shelf life of 12 months if kept in a dry store in sealed bags. If stored in high temperature and high humidity locations the shelf life may be reduced.
