The surface must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc. All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by vacuum. Pull of strength shall not be less than 1.5 N/mm2. If in doubt apply a test area first.

Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 2 minutes until a uniform mix has been achieved. To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix. Over mixing must be avoided to minimise air entrainment. Sikafloor®-320 must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment.

Prior to application, confirm substrate moisture content, relative humidity and dew point. Sikafloor®-320 is poured and spread evenly by means of a serrated trowel or pin rake. If during application locally some imperfections become visible, like trowel marks, this local spot can be treated immediately with a spike roller to eliminate the imperfection.
