Site results will be lower. Drying times may be longer. When opening to foot traffic do not subject to potential impact damage for 14 daysAchievable Surface FinishDue to the nature of the product the risk of air bubbles, pinholes and surface undulations cannot be entirely eliminated. Correct substrate preparation, effective sealing and priming and correct mixing/ application will provide optimum results. It is recommended that a Ronacrete Approved Contractor should be employed. The presence of surface imperfections will not impair the performance of the product.Substrate PreparationConcrete/screed The concrete or screed must be mechanically prepared by vacuum shot blasting or scabbling to fully remove laitance and then cleaned to remove contamination, Loose shot and dust should be removed by vacuum cleaning before the process of sealing and priming commences. Pins may be placed in the floor to set out the required levels.Ceramic, porcelain and quarry tiles Ensure all tile surfaces are clean and dry. All tiles are to be firmly bonded, any loose tiles to be removed and the area repaired with a suitable Ronacrete repair mortar. RonaScreed Feather Edge is to be used to fill grout joints to level the surface prior to priming and applying RonaScreed Flowable Base.Vinyl Tiles All tiles are to be secure and well adhered to the substrate. The surface is to be clean, dry and free from contamination.RonaScreed Flowable Base Instructions For UsePriming is always required – refer to RonaScreed Primer technical data sheetNoteMajor imperfections or deviations in the substrate may need to be made good before laying RonaScreed Flowable Base.When RonaScreed Flowable Base is applied in multiple layers, apply RonaScreed Primer between layers.Mixing/Laying RonaScreed Flowable Base may be applied either by mixer/pump Putzmeister SP 11 THF (or similar, note that continuous feed pumps may not provide adequate dispersal of components) or when mixing smaller quantities, mix with a slow speed drill ≤ 450RPM fitted with an MR3 type helical paddle and pour onto the floor. Pump or pour RonaScreed Flowable Base onto the prepared and sealed / primed surface and level with a pin rake. Spike rolling is necessary to expel entrapped air and must be completed before the mix begins to gel, to avoid leaving spike marks in the surface.For pump applications it is recommended that a contractor with the necessary experience to carry out this type of work is employed. For a list of such contractors contact the Ronacrete Technical DepartmentApplication TemperatureThe substrate and ambient temperature must not be less than 5°C on a rising thermometer at time of application. Materials should be at a temperature of 15°C – 20°C at time of application; lower temperatures will impair flow and surface finish. There should be light ventilation during and after laying. Apply the material within 15 minutes of mixing (at 20°C). Protect the fresh screed from direct sunlight during the hydration/drying process. Low temperatures will reduce the flow of the wet screed and increase the risk of surface undulations and imperfections. Take extra care when working at low temperatures.JointsIt is recommended that isolation joints are positioned in doorways. Large areas should be sub-divided by using temporary dividing strips to limit bay width, ensuring that a wet edge is maintained. Bay joints and movement joints in the substrate must be brought through into the topping.CleaningTools and equipment should be cleaned with water immediately after use. Cured material can be removed mechanically.RonaScreed Flowable Base Packaging20kg bags. Categories: All Products, Screed Pallet Deals & Bulk Buy
