Hello DIY's
My vanity porcelain/ceramic sink started to develop these unsightly cracks/marks. It feels smooth but can't seem to understand how these came about. Wanted to know if this can be fixed as the rest of the sink works perfect
Would love some help on how to repair rather than replace, thanks

Hi @Nicktrent
Welcome to the Bunnings Workshop community. It's fantastic to have you join us, and thank you for sharing your question about fixing the hairline cracks in your vanity basin,
The cracks you're looking at is a phenomenon called crazing and is often caused by thermal stress. This is when the ceramic material is exposed repeatedly to hot and cold temperatures. Unfortunately, this happens under the glaze of the basin and that's why it still feels smooth to the touch.
Because it's under the glaze there is no way to repair it, however, you can cover and recoat the basin with White Knight 500ml White Tub And Basin Paint. It dries to a tough, tile-like finish to restore previously discoloured surfaces.
Here is a handy step-by-step guide: How to paint a bath. (the technique used is applicable to your basin)
My best advice before you start painting is to make sure that basin surface is very well prepared.
Please make sure to have your doors and windows open to provide good air circulation. In the interest of safety make sure you are wearing personal protection such as gloves, goggles and a paint mask while you are using the product.
If you need further assistance, please let us know.
