Characteristics ► Good flexibility. Thermal co-efficient of expansion similar to that of concrete ► Good adhesion to both, porous and non porous surfaces ► Good mechanical properties ► Suitable for light pedestrian traffic ► Excellent durability to long term weathering effect and UV exposure ► Non toxic, therefore suitable for use in potable water applications ► Resistant to carbon dioxide and chloride ion diffusion. (Forms a film that provides an anti carbonation coating over concrete. A 1mm coating provides anti carbonation cover which is equivalent to over 75 cm of concrete) FIELDS OF APPLICATION Used as a waterproofing and protective coating for the following structures: – pile heads – internal lining for potable water reservoirs and other water retaining structures – protection of exposed concrete structures like bridge decks against carbonation and chloride attack – inverted roofs, lift and inspection pits, swimming pools, spillways – backing on marbles and granites to prevent the ingress of moisture – general construction waterproofing – wetarea (bathroom, kitchen, balcony, swimming pool and other features. – moisture vapor barrier on facade damp proofing APPLICATION INSTRUCTIONS The application temperature should be between 5°C to 45°C. Application procedures may vary slightly depending upon site conditions. The general recommended guidelines for the application of the coating system is as follows: Surface preparation The surface must be structurally sound and free of oil, grease, dust and other contaminants which will affect the bonding. Any structural cracks and potholes shall be repaired with a suitable repair mortar from the Polycrete* range of repair mortars. The surface to be treated should be presaturated with water prior to application. However, any standing water shall be removed prior to application. Mixing Polyflex is supplied in two pre-measured parts which just requires on site mixing. Do not mix more material than that can be used within the pot life. Part mixing can be carried out by mixing 3 parts of powder with 1 part of liquid (by weight). Pour the liquid into a suitable container and slowly add the powder to the liquid. Mix the contents using a slow speed drill (300-400rpm) fitted to a proprietary paddle mixer till a homogenous, lump free and creamy consistency is achieved. DO NOT ADD WATER TO DILUTE THE MATERIAL.
