If the area of the broken washing basin is small, the user can repair it themselves. Fill the broken area of the washing basin with transparent glass adhesive.

If the gaps are significant, the simplest approach is to directly apply a tube of silicone sealant into the gaps, allowing it to cure, and then gently scrape away the residue with a small knife. However, this repair method is very unsightly and leaves noticeable marks, significantly impacting the aesthetics.

If the client's requirements are particularly high, there are more complex methods worth trying, namely using ceramic and metal repair agents for repair.

Before patching, we need to thoroughly clean the area to be repaired. If possible, it is best to use a grinder to rough up the substrate. The rougher the surface, the better the adhesive will bond.

After grinding, use a blower to remove any remaining dust, then clean and wipe the surface with alcohol and a cloth. This step is to degrease the surface and enhance adhesion. After degreasing, it is generally not allowed to touch the surface with hands or other objects.

4. Thoroughly clean the damaged surface of the sink, then use a corner or handle-mounted grinder to roughen the areas to be repaired. The rougher the surface, the better. Finally, clean with acetone or alcohol to remove any residue.

2. Find a clean board to use as a container for the repair agent or adhesive. Then, mix the base material (adhesive or repair agent) and the hardener in the specified ratio, and thoroughly mix them together.

3. Apply the mixed adhesive evenly to the surface of the area requiring repair using a scraper. Carefully apply the adhesive to ensure thorough contact between the repaired surface and the adhesive, then allow it to cure.

4、The curing time should ideally be 24 hours or more. Thicker application or higher temperatures can shorten the curing time.

5. After the putty powder has hardened, tap the repaired area to check for any loose spots or unevenness. Listen for the sound to assess the curing process.

In conclusion, if your sink has been accidentally damaged, don't panic. First, determine the extent of the damage. Then, you can contact a professional for repair. This will not only ensure a professional and reliable repair, but also save you money.
