Product Description
Installing large-format vitrified tiles on high-end projects is a distinct engineering problem. Modern vitrified tiles are fired so dense that their water absorption falls below 0.5%, which means traditional cement-sand mortar cannot grip them mechanically and hollowing, cracking and detachment are the predictable results. Our Vitrified Wall And Floor Tile Adhesive (YT-300H) is a polymer-modified C2TE-class mortar engineered around premium redispersible polymer powders and high-performance water-retaining agents. It forms a dual-action bond - gripping the micro-texture of the tile backing while anchoring to the concrete substrate - and retains enough flexibility to absorb structural vibration, building settlement, and the repeated thermal expansion and contraction that heated floors and external facades demand. Its long open time of up to 30 minutes and slip resistance below 0.5 mm let installers place and adjust heavy panels on vertical walls without sag.
Scale matters on C2 products because polymer dosage controls both adhesion and flexibility. We run this adhesive on our fully automatic special dry-mix mortar line under computerized batching, testing incoming raw materials and every finished batch against C2TE (EN 12004) requirements. For overseas distributors and engineering contractors, that level of control translates directly into fewer after-sales repair claims and fewer structural failures on landmark commercial work. As the earliest-established and largest-scale specialized dry-mix mortar manufacturer in Zhejiang, with over 60 national patents, we supply a certified, repeatable C2 system rather than a one-off mix.

Applications
- Indoor and outdoor walls and floors of large-format vitrified tiles - the C2 bond overcomes the <0.5% water absorption that defeats ordinary mortar.
- Heavy-traffic commercial floors, subway stations, airport lounges and shopping malls - high bond strength and flexibility withstand dynamic loads and thermal movement.
- Underfloor heating and swimming pool environments - the water-retaining, flexible formula survives temperature cycling and continuous wetting without delamination.
Customization
Packaging design and bag size (20 kg or 25 kg); formulation adjustment of setting time for tropical or cold climates; polymer content can be tuned to match local building codes through our R&D center.
Packaging & Transportation
25 kg multi-layer moisture-proof valve bags; 40 bags per pallet, shrink-wrapped with protective corner boards. Shipped in 20 ft full containers EXW Deqing, close to major East China ports.
FAQ
Q: Is this adhesive suitable for underfloor heating?
A: Yes. The flexible, polymer-modified bed absorbs thermal expansion and contraction cycles, which is why it is specified over heated screeds and temperature-cycled floors.
Q: What does the C2TE classification mean?
A: C2 indicates enhanced tensile adhesion (≥1.0 MPa), T denotes extended open time, and E denotes reduced slip, per EN 12004. It is the relevant class for dense, low-absorption vitrified and porcelain tiles.
Q: Can large vitrified tiles be installed on vertical walls without slipping?
A: Yes. The slip resistance is ≤0.5 mm and the ≥30-minute open time allows heavy panels to be positioned and adjusted on vertical walls before the bed sets.
