Bailishi Flexible Tile Adhesive for Sintered Stone & Large Format Panels

Bailishi Flexible Tile Adhesive for Sintered Stone & Large Format Panels is a mortar product formulated from carefully selected premium natural inorganic mineral raw materials. It is designed for indoor installation of large-format tiles and sintered stone, providing strong adhesion for low-water-absorption materials. The product is easy to apply, easy to adjust and press, and its thin-bed installation effectively reduces space loss. Green, safe, and worry-free for tile fixing.

Application Range

• Suitable for direct application on concrete, cement render, concrete slabs, and rendered brickwork
• For indoor wall installation of sintered stone, large format panels, and facing tiles with water absorption >0.5%

Surface Preparation

• Sintered stone and large format panel surface treatment: The bonding surface must be brushed with a steel wire brush to remove surface release agents
• All surfaces must be flat, sound, clean, free of hollows, oil, wax, release agents, and other loose materials
• Concrete surfaces must be cured for at least 28 days before tiling
• Newly rendered surfaces must be cured for at least 7 days before tiling
• Old concrete and rendered surfaces can be cleaned with industrial detergent or degreaser, then rinsed thoroughly with high-pressure water and allowed to dry for 24 hours before tiling
• Remove residues on concrete surfaces, especially release agents remaining on concrete slabs
• On highly absorbent substrates or in high-temperature, dry environments, it is best to dampen the substrate to an externally dry but internally moist condition before construction

Construction Method

It is recommended to apply with a notched trowel as follows:

• Spread the adhesive onto the working surface with a notched trowel to form uniform ridges. Do not spread more than 1m² at a time, depending on weather conditions
• For double-buttering, apply adhesive to both the working surface and the tile back
• Press the tile into place within the open time
• The choice of notched trowel size should consider the flatness of the working surface, the tile size, and the concavity/convexity of the tile back

Reference Dosage

The theoretical coverage of Bailishi Flexible Tile Adhesive for Sintered Stone & Large Format Panels is approximately 1.5kg per square meter per 1mm thickness. Actual consumption depends on substrate flatness and tile size.

Precautions

• Use the product by adding water according to the recommended ratio only. Do not add other materials
• Natural minerals are used as raw materials; color differences between batches are normal and do not affect normal use
• Construction temperature: 5–35°C. Water-to-powder ratio may be adjusted appropriately depending on substrate, weather, and construction conditions
• When working in rainy weather, ensure adequate protection and keep the work area free from rain exposure for 24 hours after tiling
• Mortar should be used within 2 hours depending on weather conditions
• Never mix water into already set mortar for reuse
• After tiling, wait until the adhesive has fully cured before proceeding with grouting
• Adhesive should be spread evenly and tiles fully covered. The bonding layer thickness should be approximately half the height of the notched trowel tooth pitch
• Leave a gap of ≥2mm between tiles during installation
• For wall tiling, provide temporary fixing or bracing as necessary

Shelf Life

Store unopened products in a dry, cool, and well-ventilated place. Under normal storage and transport conditions, the shelf life is 12 months.
