Acrylic modified elastomeric cementitious waterproofing and protective coating for concrete


Two component, acrylic cementitious coating which cures to form a tough and flexible coating having excellent waterproofing properties


  • Good flexibility 
  • Good adhesion to both, porous and non porous surfaces 
  • Good mechanical properties 
  • Good abrasion resistance. Suitable for pedestrian traffic 
  • High durability to long term weathering effect and UV exposure 
  • Non toxic, therefore suitable for potable water applications 
  • Resistant to carbon dioxide and chloride ion diffusion 
  • Can be applied to 24 hours old concrete, there by giving immediate protection to the concrete. 
  • Allows the substrate to breathe

Step by step


The surface must be structurally sound and free of oil and grease, dust and other contaminants which will affect the bonding.Any structural cracks or potholes shall be repaired with a suitable repair mortar from the Polycrete* range of repair mortars. Light mechanical grinding or high pressure water jet cleaning of the concrete surface can be done to remove any contaminants from the surface. The surface to be treated should be presaturated with water prior to application. However, remove any standing water from the concrete surface just before applying the coating.


Polyflex Combo 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 only exact half the quantity supplied on both components. Pour the liquid (2 cans) 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 until a lump free creamy consistency is obtained. DO NOT ADD WATER TO DILUTE THE MATERIAL AT ANY STAGE


It is recommended to apply Polyflex Combo in two coats to provide a minimum thickness of 2mm. Each coat shall be applied @1.4 kg/m2 which will give a dry film thickness of 1mm. The coating can be applied with a stiff brush or an airless spray of nozzle size of 3-4mm and a pressure of 6-7 bars. After the application of the first coat and whilst it is still wet, embed a CL 252 mesh in all the corners and other joints for added reinforcement. The second coat shall be applied after the first coat dries. for protection against carbonation and alkali attacks, the coating can be applied in minimum 1mm thickness.


The coating shall be cured immediately after it dries by wet hessian cloth or mist spraying for a minimum period of 72 hours. The coating will achieve its full mechanical properties within 7 days at 25°C & 50% RH.


Clean all tools immediately with water after use.Hardened materials can be removed mechanically only.
