Damaged white quartz worktop.

Today, our company, Worktoprepair.com, visited a customer's house where they had damaged their quartz worktop. The damage was quite serious; the pure white quartz had a large piece missing from the surface. This was caused by a large object falling from a height. We also noticed significant staining in the sink area. The quartz was installed about two years ago by another company, not by us. This is a common issue with white quartz because it was not highly polished and has more of a semi-sheen finish. It is prone to staining, especially from teabags and food coloring. White quartz always looks better with a high-gloss sheen on the surface and lasts longer.

I began my repair process by sanding the surface using a full set of diamond quartz polishing pads along with water, washing-up liquid, and putty powder—this is my secret recipe. There is a knack to this. The kitchen cupboards and floor had to be covered up to prevent water from going everywhere in the kitchen. After this polishing process, the stains on the quartz worktop were completely removed.

Once all the tops were cleaned, I continued my repair, which involved filling in the missing piece of worktop with a colored resin to match the existing color. This had to be sanded and blended into the surface while matching the same sheen as well. The edge of the worktop also required sanding and re-polishing at the chamfer of the worktop. Additionally, I needed to redo the joint that originally contained silicone; I removed it and finished the joint with resin before polishing it in so that it would hardly be noticed afterward. Joints are best filled with resin rather than silicone because they will last much longer and will not stain. Every joint on a worktop needs good support along with a biscuit joint to prevent movement; if I put resin in a joint that hasn't been properly supported underneath, it will chip out due to movement. Many granite and quartz worktops I've encountered during my repairs lack sufficient support underneath, causing joints to move and subsequently leading to silicone or resin being dislodged.
