High-Pressure Water Roughening

• Eliminates the need for secondary patching, prevents issues such as hollow sounds, cracking, and delamination, ensures more reliable waterproofing, and is suitable for both formwork‑cast and precast wall applications.
• It delivers higher work efficiency: a single high-pressure water roughening machine requires only two operators and can roughen 600–800 square meters in an 8-hour shift, achieving several times the productivity of manual labor. After high-pressure water roughening, processes such as slurry spraying, adhesive application, and cement mortar preparation are eliminated.

　　So‑called high‑pressure water roughening refers to the roughening process carried out using a high‑pressure water roughening machine. This equipment employs high‑pressure water jet technology to create a textured surface on concrete substrates and interior wall panels, enabling rapid surface roughening while minimizing quality risks such as hollowing caused by residual laitance or release agents. As a result, it significantly enhances the bond strength of wall tiles and improves the overall quality of tile installation.
