C0 is a general-purpose adhesive for indoor floors and walls with tiles up to 600 x 600 mm. C1 offers extra bond strength for indoor/outdoor use, supports larger-format tiles up to 800 x 800 mm, and adds freeze-thaw resistance for exterior applications.

It supports glazed wall tiles up to 300 x 600 mm, vitrified tiles up to 400 x 800 mm, and floor tiles up to 800 x 800 mm.

Yes, C1 is suitable for bonding paper-faced mosaic tiles in addition to standard glazed, vitrified, and floor tiles.

Coverage depends on the trowel notch size and tile format. Applied with a notched trowel, each working batch covers approximately 15–18 m² before re-troweling is needed — contact us for a coverage estimate based on your specific tile size and substrate.

It meets a freeze-thaw bond strength of ≥0.5 Mpa under JC/T 547-2017 testing, giving it good durability for outdoor and cold-climate tiling applications where C0 adhesive is not rated.

It complies with JC/T 547-2017 “Adhesives for Ceramic Tiles,” meeting C1 technical requirements.
