Immediately prior to the application of SewperCoat® Flowable, this water should be removed from the formwork. Mixing Care should be taken to ensure that SewperCoat® Flowable is thoroughly mixed. A forced-action mixer is essential. Mixing in a suitably sized drum using an approved spiral paddle in a slow speed (400/500 rpm) heavy-duty drill is acceptable. Free-fall mixers must not be used. Mixing of part bags should never be attempted. It is essential that machine mixing capacity and labour availability is adequate to enable the placing operation to be carried out continuously. Measure 2.4 - 2.6 litres of drinking quality water and pour three-quarters into the mixer. With the machine in operation, add one full 20 kg bag of SewperCoat® Flowable and mix for one minute before adding the rest of the water. Mix for a further 2 - 3 minutes until a smooth even consistency is obtained. Note that powder must always be added to water. The quantities mixed may be scaled up as required. Placing The mixed material should be placed within 15 minutes of mixing in order to gain the full benefit of fluidity and of the expansion process. If placing by pump, standard concrete pumping practice should be followed. The pump and pipeline should be primed with a slurry of calcium aluminate cement and water. DO NOT use slurry of Ordinary Portland Cement (OPC). Any residue of OPC in the hose or equipment will flash set the SewperCoat Flowable and cause blockages to equipment. SewperCoat® Flowable when used for reinstatement of horizontal areas, must be suitably restrained by formwork. Curing Correct curing is essential to ensure optimum performance of the product. The formwork should be left in place until the compressive strength of the SewperCoat® is 10 MPa, however it is recommend that the formwork be left in place for at least 24 hours if possible.

SewperCoat® Flowable is a cement-based concrete reinstatement material. In common with all cementitious materials, SewperCoat® Flowable must be cured immediately after the formwork is stripped in accordance with good concrete practice. Immediately after striking the formwork, all exposed faces of the repair should be thoroughly soaked with clean water and then sprayed with a liquid curing membrane such as Concure A99. Any delay in starting the curing process after the formwork is stripped will adversely affect the performance of the product. In fast drying conditions, supplementary curing with polythene sheeting taped down at the edges must be used. In cold conditions, the finished repair must be protected from freezing. Supply SewperCoat® Flowable is supplied in 20KG Bag. Coverage and yield Approx 2.4 Tonnes per m³ (Approx 8.3L/20KG bag) Limitations SewperCoat® Flowable is a protective mortar lining system, care should be taken when considering use for structural applications. Please contact Parchem Construction Supplies for further information. Storage As with all hydraulic binders, SewperCoat® Flowable must be stored in dry conditions, off the ground. In this case, it will retain its properties for at least 6 months. In many instances, experience has demonstrated that properties are retained for more than one year.6 months. In many instances, experience has demonstrated properties are retained for more than 1 year. SewperCoat® Flowable
