Roff Non-Skid Adhesive (NSA) is well suited to bathroom floor tiling because it is designed for natural stones, terracotta and regular-size vitrified tiles on floors, areas where slip resistance and reliable grip matter most. It offers strong adhesion on horizontal surfaces and works well in the humid conditions typical of Indian bathrooms. For added protection against water seepage under the tiles, it is commonly paired with Roff Hyguard Ex waterproof coating before tiling begins. A Roff technical expert or the Adhesive Selector tool on roff.in can confirm the right match for your specific tile type.
