This is neither a sealer nor a wax. Guard Slip Resistant reacts with the silica already present in the stone or concrete and creates a micro-structure that improves grip - including when the floor is wet.
So there is no layer to wear away or peel off, and the appearance of the surface usually stays the same. Some shiny floors may dull slightly, so start with a test in an inconspicuous spot. Nor is there any roughening, so the floor does not collect dirt more than it did before.
It works after a single application, and its water-based formula does not cause corrosion - so it also suits sensitive stone, which traditional etching methods damage. It performs superbly on patios, drives, pool surrounds and kitchen floors.
