This video is a quick demonstration of just how aggressive the initial grab of AF207 is when used in conjunction with Ardex FLEXBONE UI740. The uncoupling Matt shown was placed into fresh AF 207 material approximately 12 hours prior to the recording of this video. The significance of the remaining tech of the AF 207 is that any disbonding issues regarding tile removal, replacement, and or adjustments during the setting process will not affect the integrity of the bond of the mat to the substrate.
