Fireclay is a unique material used to make sinks and tubs. It maintains the appearance of porcelain or ceramic, but because the clay is so heat- and fire-resistant (it is created at a much higher temperature), the material’s resilience is increased.
Fireclay rarely suffers from chips or scratches, but when it does you can acquire a repair kit from your sink’s manufacturer to reinforce the damaged area with similar damage-resistant material.
- Clean the damaged area with a rag dampened in warm water and an all-purpose sink cleaner. Mildly abrasive cleaners are fine for removing any stains in the damaged area. If necessary, use a solvent cleaner, such as mineral spirits, to remove grease or wax.
- Dry off the area thoroughly with a lint-free cloth. Shake your fireclay repair compound that comes with your repair kit for two full minutes to ensure that it is ready for use.
- Apply the compound to the damaged area with the provided applicator. If the kit does not come with an applicator, use a toothpick or cotton swab to spread the repair compound. Make multiple passes, applying thin layers of compound until the damaged area is completely covered.
- Protect the repaired area from moisture and pressure for at last 24 hours so that the compound can dry fully.
If you use a repair kit made for porcelain or ceramic, you may not achieve the same resilient finish or color matching for your sink repair. If at all possible, obtain a repair kit designed specifically for your sink from your product’s manufacturer.
