With its extended working time, fresh mixes of ARDEX K 39 can be easily smoothed into existing pre-applied material up to 40 minutes after application. This gives the installer more time to focus on creating the perfect subfloor, with no trowel marks, ridges or joint marks, and additional preparation the next day.
Coverage: Approximately 7.4m2 at 2mm thick per 22kg bag
