YTII reaches Grade T vertical anti-sag performance, solving the core pain point of oversized stone sliding on vertical walls. Its S1/S2 flexible buffer layer offsets thermal deformation between concrete base and dense stone, stopping tile surface cracks. Ultra-high initial bonding strength locks heavy granite and ultra-thin rock slabs firmly, completely eliminating post-construction hollowing and detachment safety hazards for high-end decoration projects.
Purified low-alkali formula blocks alkali salt penetration into porous marble and travertine, avoiding ugly dark staining and discoloration that ruin stone decorative effect. Excellent water and freeze-thaw resistance makes it suitable for long-term wet environments such as bathrooms, balconies and exterior facades, with stable bonding strength even under alternating hot & cold floor heating cycles.、
Strict fixed mixing proportion, mechanical stir and 2–3 mins maturation before use; all mortar must be consumed within 2 hours. Adopt double-buttering method for slabs over 300mm to ensure full back coverage. Require substrate flatness deviation ≤2mm under 2m straightedge and concrete moisture ≤4%. Thin-bed laying saves material and reduces building load, supporting batch construction of residential villas, commercial malls and high-rise exterior stone projects with consistent stable performance..
