Clean the surface of all dust, dirt, oil & grease, cement laitance and all loosely adhering particles. New concrete surface shall be at least 28 days old and the surface moisture content less than 5%. Surface irregularities and blow holes shall be repaired with Polypoxy BF or Polycrete ST. The surface after carrying out the necessary cleaning shall be vacuumed for removing the dust debris left over after the cleaning process. The surface shall be primed with Polyprime EP @ 4-5 m2/L. For highly porous substrates, a 2nd coat may be required. The coating shall be applied within 24 hours of application of the primer. If the primer surface is left open for more than 24 hours, then a fresh coat of primer has to be re-applied.

Polypoxy SL 20 is supplied in three pre-weighed packs. Part mixing is strictly prohibited. Take a suitable container and pour the resin (A) into it. Add the hardener (B) into the resin and mix thoroughly with a paddle mixer. Use of a slow speed drill is recommended to reduce the formation of air bubbles. Then slowly add the filler (C) into the container and mix thoroughly for a few minutes. Ensure sufficient labor and material is available at site to ensure a smooth continuity of the application of the flooring. Apply the Polypoxy SL 20 topping, by pouring on to the primed surface and spread with a steel notched trowel to achieve a 1mm to 4mm seamless topping. Once the material is evenly spread, continuous spiking with a spiked roller is to be done to remove all entrapped air. Spiking adjacent layers is recommended to be done at 50% overlaps.
CAUTION
– do not use below 5°C
– over troweling is to be avoided
– Polypoxy SL 20 should not be applied to surfaces which has rising dampness and there is a phenomenon of reverse osmosis. In addition to that, application is always recommended to be carried out when the atmospheric temperature is low. 

Store in a dry, cool and shaded area. Protect from sunlight, frost and high humidity. In tropical climates, store the material in air conditioned area at less than 25°C. The shelf life of the product is 12 months if stored as per recommendations. Exposure to heat and high humidity will result in the premature deterioration of the product and reduce its shelf life considerably
