Shannon Lush looks at how to repair broken grout naturally.
1. First clean the surface with bicarb soda and white vinegar (and an old toothbrush to penetrate the nooks and crannies).
2. Then grate white candle wax in a bowl and apply it to the crack and melt with a heat gun – you can buy these for $20 from hardware outlets.
3. Push it in evenly using a finger wrapped in a cloth. Remove any excess with a knife. Wax is cheaper than silicone and mould won’t grow behind it easily.
