Ensure that the concrete floor is 28 days old and the surface moisture content less than 5% prior to the application of the primer. Clean the surface of all dust, dirt, degradable type of curing compound, oil and grease, cement laitance and other contaminants which will affect the bonding. Captive/shot blasting and grinding of the concrete surface is recommended for cleaning the surface. Cracks, blow holes and surface imperfections should be repaired with Polypoxy BF or Polycrete ST (repair mortar). For larger areas, a scratch coat can be applied. The scratch coat can be prepared by mixing Polyprime EP with Aggregate No. 8. The scratch coat can be applied by a notched trowel.

Pour Part B into the Part A pail and mix thoroughly with a mixing paddle for 1-2 minutes till a homogenous and uniform consistency is achieved.It is always recommended to mix a complete kit at a time. However, for small areas, part mixing may be carried out by employing proper weight measures. The mixed primer shall be applied within the working time of the product. The primer may be applied by brush, roller or squeegee. Polyprime EP shall be applied at a coverage rate of 4-5 m2/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. 

Store the 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.
