NCL Cerostik is a cement based polymer modified, thin-bed adhesive for fixing Clay & Ceramic Tiles on leveled walls & floors. It is a high quality factory pre-mixed dry powder with special chemical additives and inorganic fillers. It provides good bonding strength and full coverage to the tile surface, thereby providing full bed, sound and long lasting installation as compared to hollow and weak installation with conventional mortar. Cerostik is suitable for use on most masonry and concrete surfaces.

The surface should be dry, clean and free from dust, grease, Oil and other contaminates. Keep ready - mixing tools, trowel, hammer, notched trowel, joint spacers, sponge etc.
Cement based Surfaces: Screeds must be properly cured for 7 days. Cure the concrete for 3 weeks prior to tiling. The surface should be properly leveled for best outcome. Remove curing compounds and any other foreign matter before application which leads to de-bind the tile adhesive.
Painted Surfaces: Already painted / lime etc. coated surface should be removed by wire brush Or mechanically and loose peeling paint should be removed completely. Allow the surface to dry after cleaning.
In a clean tub take 75% of recommended water and gradually add supplied tile adhesive in it. Mixing can be done manually or by mechanical slow speed stirrer. Based on the material consistency adjust the water and mixing to be done till homogenous lump free mix is obtained. After proper mixing,leave the paste for 5 minutes for polymeric dispersion before application. The paste should be kept away from direct sunlight, heat and use within 120 minutes of preparation (after mixing with water).
