Quick Links - Click To Jump To Section:     Features & Benefits Application Notes Limitations Features & Benefits General purpose grout for most standard applications Non-shrink High strength Chloride free Can be used at flowable or trowelable consistency Supplied as a ready to use dry powder. The low water requirement ensures high early strength and long-term durability Conbextra GP is a blend of Portland cements, graded fillers and chemical additives. The filler grading produces a highly flowable grout which will not segregate or bleed Class A1 Non-Combustible Fire Classification Fosroc Conbextra GP is non-flammable Yield: Allowance should be made for wastage when estimating quantities required. The approximate yield per 25 kg bag for different consistencies is: Trowelable - 12 litres Flowable - 13.25 litres Please refer to the Product Data Sheet for full details of: Specification Clause Properties Mixing Application Instructions Coverage Cleaning Storage Health and Safety Application Notes For a minimum of 2 hours prior to grouting, the area of cleaned foundation should be flooded with fresh water Immediately before grouting takes place, any free water should be removed Particular care should be taken to blow out all bolt holes and pockets Where water soaking is impossible contact our Technical Department on 0113 2455450 (option 2) or send a message to technical@rawlinspaints.com for advice Place the grout within 20 minutes of mixing to gain the full benefit of the expansion process For mixing quantities up to 50 kg a 1150 watt, 280 to 640 rpm, 110 volt drill, fitted with an MR3 Mixing Paddle is suitable For best results a mechanically powered grout mixer should be used Larger quantities will require a high shear vane mixer. Do not use a colloidal impeller mixer Mixing Ratios: Flowable: 4.0 - 4.5 litres of water per 25Kg bag Trowelable: 3.4 - 3.6 litres of water per 25Kg bag Please see the Product Data Sheet for detailed information. Limitations Low Temperature Working: When the air or contact surface temperatures are 5°C or below on a falling thermometer, warm water (30°C to 40°C) is recommended to accelerate strength development Substrates should be free from ice 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, specifically protecting the grout from freezing in the first 48 hours after placing 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
