Surface preparation
Surfaces should be sound, stable, clean and free from loose laitance, paint, oil, grease which may cause debonding. It is recommended to open capillaries by means of sand blast or steel brush before applying ADMIX FL680. Areas should be saturated to prevent absorption. But free flow water should not exist.
Mixing
Pour 90% of the resin component into the mixing pan, add powder component slowly and mix, using a suitable slow speed (300-400 rpm) mixer, continue mixing until a smooth paste free from lumps is obtained, then remainder of the resin can be added, continue mixing until all the resin is absorbed.
Placing
Pour the mixed material onto the previously profiled surfaces. Use a steel pin screed or squeegee to spread the product to the required thickness. As soon as possible after leveling, roll the material with a spiked roller to release trapped air and achieve a flat surface.
