A fast setting polymer fortified adhesive mortar for use on floors in internal & external locations. Formulated with Rock-Tite polymeric binders it is highly versatile & is particularly suitable for the installation of large format materials where it provides solid bed coverage without the need to back butter. Its shrinkage compensating formula allows it to be used between 3-25mm where it can be used to level uneven floors. Ideal for use with underfloor & under tile heating. When fixing light coloured or translucent natural products please check for staining before use.
