Hole repair and surface restoration in stone processing are crucial steps in determining the quality of the finished product. The following plan, taking into account the characteristics of natural stone, systematically explains the complete process from hole repair to overall renovation, covering key technical points such as material selection, color matching techniques, grinding and polishing, and crystallization treatment. It can serve as a reference for stone processing and maintenance personnel.
Holes, sand holes, cracks, and joint defects are common quality defects in stone processing and subsequent use. To restore the decorative effect and structural strength of the stone, a systematic and scientific repair and restoration solution is needed. This solution covers the entire process from pretreatment during raw material processing to post-installation surface renovation.
- For holes, sand holes, missing corners and cracks on the surface of stone, the core process of “cleaning the joints – mixing the adhesive – filling – curing – polishing” is mainly adopted.
- To enhance overall aesthetics and prevent dirt and grime from accumulating in the gaps, seamless treatment is required.
- For stones that have gaps (height differences) after installation or have lost their luster due to aging, overall grinding is required.
- After grinding, a protective layer is formed through chemical crystallization, which enhances the hardness and gloss of the stone.
