Dual Construction Process for Indoor & Outdoor Paving


YTIII supports two flexible construction solutions: traditional wet mixing trowel filling for interior tile walls/floors; dry-spray watering curing for large outdoor plaza PC pavers. Both methods form dense, waterproof joint layers to lock out rainwater and underground moisture, solving outdoor pavement freeze-thaw damage and interior bathroom water seepage issues.


Low Shrink Flexible Grout with Anti-Efflorescence


Optimized low-shrink formula eliminates common dry joint cracking. Built-in flexibility offsets thermal deformation between stone and substrate, suitable for temperature-varying outdoor environments. Anti-efflorescence ingredient restricts ugly white salt bloom on light-colored marble and light grey pavers, maintaining consistent decorative color year-round. High compressive & flexural strength delivers heavy pedestrian wear resistance for plazas and residential walkways.


Standardized Operation & Long-Term Surface Protection


Wet process workflow: accurate water mixing, mature 3–5 mins, fully compact joints with rubber float, wipe excess with damp sponge before initial set. Dry process workflow: evenly spread dry grout into gaps, sweep flat, mist water slowly, cure 24–48h. Keep finished joints free from foot traffic within 24h post construction. Wide color selection matches all stone & tile designs, unifying decorative appearance while providing permanent waterproof sealing protection for the whole paving system.
