How to use


Clean the concrete surface of all loose particles, laitance, dust, oil, grease, paint etc. Grit/captive blasting and mechanical grinding of the concrete floor is recommended for removing all surface contaminants.


Polypoxy BF Part A and Part B shall be mixed thoroughly using a proprietary paddle mixer fitted to a slow speed drill till a uniform color and consistency is achieved. It is recommended to mix an entire kit at a time. However, for small repairs, part mixing can be done provided both the parts are accurately measured by weight. Application can be carried out by a steel trowel or putty knife or scraper. Press firmly the mixed mortar into the area to be filled to ensure proper adhesion and full contact. The epoxy putty shall be applied at a maximum thickness of 5mm in one layer. Additional layers should be applied after the applied mortar achieves its initial cure. The area repaired with Polypoxy BF can be over-coated with any epoxy or polyurethane coating after it achieves its initial cure. 


The pails shall be stored in a covered and dry area. In tropical climates the product should be stored in an airconditioned environment. The shelf life of the product in unopened condition is 12 months from the date of manufacture. Exposure to sunlight, UV, sources of heat and humidity will result in the deterioration of the product and reduce its shelf life.
