Application, Advantages and Solutions:– Replacing 1/3 of the required water with ice, in warm months will allow for further work time – Add Iron Oxides if required to achieve desired colour – Cure concrete under white geo-fab, plastic and packing blankets for best curing results – Alpha Powder Water Reducer will assist in achieving a high fluid mixImportant Information:3.2-3.4kg chilled water per 20kg bag Mechanical mix 10-15 minutes Direct Cast Method: PVA 15: 140g per 20kg PVA 100: 40g per 20kgMixing Instructions:Use clean, dry mixing equipment (screed mixer or pan mixers are recommended) – Dry blend Alpha ECC Premix with Iron Oxide – Add water and blend – Add ice and continue blend until homogeneous. – After initial blend, slowly add PVA / High Disperse Fibres within your mix. – If a more fluid consistency is required, small dosages of Alpha Powder Water Reducer can be slowly introduced within the mix.Note: Ensure fibre’s are fully dispersed throughout mix.Casting Technique:Alpha ECC Premix is a highly engineered mix. This mix is allowing for burnishment on the topcoat. ECC can be precast, cast in-situ as well as off form. Recommend to follow the fibre loadings set out within the above mix instructions for best successCuring:To ensure that concrete reaches its maximum potential, place white geo-fab, layer plastic sheeting followed by packaging blankets will keep the moisture from escaping. Demold after 24-48 hours, depending on environment and weather conditions.Polishing:Polishing can be done wet or dry. To maintain the cream layer, lightly polish the concrete using pads that are 200 grit or 400 grit. To achieve a sand exposure finish begin grinding with coarser grit pads, progressing to finer grits until desired exposure is reached.Sealing:Allowing your concrete to cure full prior to sealing for optimum sealer performance is essential. Sealing your concrete using Alpha Concrete Countertop Sealer. Refer to Alpha Concrete Countertop Sealer guide for sealing application.
