Designed specifically for Natural Stone and Large Format Tiles, CLF-03 is semi-pourable and can be used up to a bed depth of 25mm. It can be used to build-up uneven floors in small areas prior to fixing tiles – without the use of a levelling compound. Highly flexible, it is ideal for use on overlaid timber floors or areas of vibration and movement. It is also ideal for use with under tile heating. Because you can grout in only 3 hours, it is ideal for fast track project completion.
