The surface should be dry, free of any cement laitance, oil and grease, curing compound and any other contaminants, which may affect the bonding. New concrete surfaces should be 28 days old and the moisture content on the surface must be less than 5%. Surface irregularities and blow holes shall be repaired with Polypoxy BF or Polycrete ST. The surface should be vacuumed ahead of priming. Prime the prepared surface with Polyprime PU @ 4-5m2/L. The coating is applied when the primer is dry. However, in all circumstances, 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. Broadcast Aggregate No. 3 on the primer whilst it is still wet @0.3 kg/m2. On ramp and turning areas, the aggregate shall be broadcasted @1.2-1.5 kg/m2. After the primer dries off brush away or vacuum out the excess aggregates.

Top coat Polypur TC 20 shall be applied as the abrasion resistant top coat. This UV resistant coating is supplied in two preweighed packs (resin & hardener). Stir both components seperately for a minut to remove any sediments. Slowly add the hardener (B) into the resin (A) and mix thoroughly with a slow speed drill with a proprietary paddle mixer for 2 -3 minutes, until a homogenous consistency is obtained. Work the mixer round the mixing pan to ensure it scrapes the side and bottom of the pail. Once the material is mixed immediately apply the coating with a roller or airless spray at a coverage rate of 5m2/L. If required apply a second coat at the same coverage rate and only after the first coat has dried off completely (24 hours). The coating will achieve its full mechanical properties after 7 days of cure, after which the floor can be subjected to heavy traffic. 

Store all material in a cool, covered dry place. Do not expose the pails to direct sunlight and keep away from all sources of heat. In tropical climatic conditions, the product has to be stored in an airconditioned environment and protected from high humidity. The shelf life of the product is 12 months in unopened condition if stored as per the recommendations. Exposure to high temperature and humidity will result in considerable deterioration of the product and reduce its shelf life.
