The product is also suitable to hide concrete repaired areas, visual differences with the host concrete. Dekguard O is suitable for use on all types of structures, especially those in aggressive marine and coastal environments. It is equally suitable for new and existing structures. Dekguard O is a component of Parchem’ Renderoc system of concrete reinstatement. Advantages „ Reduces different appearances between concrete sections and / or repaired patches „ Excellent barrier to carbon dioxide, chloride ions, sulphates, oxygen and water „ Allows water vapour to escape from the structure „ Highly UV-resistant aliphatic acrylic gives exceptional resistance to the effects of long-term weathering „ Highly durable in all climatic conditions „ Matt finish Description The Dekguard O system comprises a single-component, penetrating silane-siloxane primer and a single-component translucent coating, both ready for immediate site use. The primer (Dekguard Primer) is supplied as a clear liquid and is based on a silane-siloxane dissolved in a penetrating organic carrier. The primer is reactive and capable of producing a chemically-bound hydrophobic barrier, thus inhibiting the passage of water and water-borne contaminants. Dekguard O is an aliphatic acrylate, solvent based protective coating, providing outstanding resistance to aggressive elements, UV light and rain. Technical Support Parchem offers a comprehensive range of high performance, high quality repair, maintenance and construction products. In addition, Parchem offers a technical support package to specifiers, end-users and contractors, as well as on-site technical assistance. Design Criteria The coating should be applied in two coats to achieve a total dry film thickness of not less than 150 microns. To achieve the correct protective properties, Dekguard O system must be applied on to the substrate at the coverage rates recommended. Specification Clause Protective/ decorative surface coating The protective coating system shall comprise Dekgaurd Primer, a penetrating Silame- Siloxane primer and Dekguard O, a single component aliphatic acrylate coating suitable for application by brush, roller or spray. The total dry film thickness of the coating must be not less than 150 microns and exhibit the following performance charicteristics. Fosroc® Dekguard O June 2014
