Advantages „ Low VOC - 78.0 grams per litre „ Australian made „ Provides protection from water, carbon dioxide and chloride ions to concrete „ Suitable for application to a wide range of surfaces „ Resistant to long term weathering „ Safe to use, water borne formulation „ Range of decorative colours „ Good abrasion and impact resistance „ Excellent resistance to embrittlement „ Allows water vapour to escape from structure „ Excellent mould and fungi resistance „ Good opacity Description Emer-Impact is a single component, water borne, high performance, acrylic coating which can be applied by roller or spray to achieve a range of finishes. It has excellent weathering properties and is resistant to mould and fungal growth. Emer-Impact dries to a satin finish and has excellent weather proofing properties whilst allowing moisture in the substrate to escape. Technical support Parchem offers a comprehensive range of high performance, high quality products suitable for use within all aspects of the concrete repair and protection industry. In addition, the company offers a technical support package to specifiers, end users and contractors, as well as on-site assistance.
