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 Renderoc LA55 is 10 MPa or as otherwise specified by the Supervising Officer. Renderoc LA55 is a cement-based concrete reinstatement material. It is recommend that the formwork be left in place for as long as practically possible to provide the best curing conditions. In common with all cementitious materials, Renderoc LA55 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. Overcoating with protective decorative finishes Renderoc LA55 is extremely durable and will provide excellent protection to the embedded steel reinforcement within the repaired locations. The surrounding parts of the structure will generally benefit from the application of a protective barrier/decorative coating to limit the advance of chlorides and carbon dioxide, thus bringing them up to the same protective standard as the repair itself. Parchem recommend the use of the Emer Clad and Dekguard range of protective, anti-carbonation coatings. These products provide a decorative and uniform appearance as well as protecting areas of the structure which might otherwise be at risk from the environment. All traces of form-release oils and curing membranes must be removed prior to the application of Dekguard products. This is best achieved by light grit or sand-blasting. Cleaning Renderoc LA55 and Concure WB30 should be removed from tools, equipment and mixers with clean water immediately after use. Cured material can only be removed mechanically. Equipment used with Nitoprime Zincrich should be cleaned with Solvent 10. Limitations Renderoc LA55 should not be used when the temperature is below 5°C and falling. Do not mix part bags under any circumstances. The product should not be used to reinstate horizontal areas where the surface would remain unrestrained during cure. It should not be exposed to moving water during application. If any doubts arise concerning temperature, application or substrate conditions, consult your local Parchem sales office. Estimating Supply Renderoc LA55 product code: 302030 Renderoc LA55: 20 kg bag Nitoprime Zincrich: 1 litre can Concure A99: 20 and 205 litre drums Solvent 10: 4 and 20 litre cans Coverage and yield Renderoc LA55: Approx 10 litres / 20 kg bag Nitoprime Zincrich: 7 m²/litre Concure A99: 5 m²/litre Notes: the coverage figures for liquid products are theoretical - due to wastage factors and the variety and nature of possible substrates, practical coverage figures will be reduced. Storage Shelf life All products have a shelf life of 6 months if kept in a dry store in the original, unopened bags or packs. Storage conditions Store in dry conditions in the original, unopened bags or packs. If stored at high temperatures and/or high humidity conditions the shelf life may be reduced.
