Here's why:
* Incompatibility: Nail varnish is formulated with specific solvents that allow it to properly adhere to the nail and dry to a smooth, durable finish. White spirit is a different type of solvent (typically a petroleum-based solvent). Mixing the two can cause:
* Separation: The mixture may separate into different layers, ruining the varnish.
* Poor Drying: The thinned varnish may not dry properly, leaving a sticky or tacky finish.
* Brittle Finish: The varnish may become more prone to chipping and peeling.
* Color Changes: The color of the varnish could be altered.
* Damage to Nails: The altered chemical composition of the mixture can make the nail vanish more likely to cause nail damage.
* Proper Thinners: The best way to thin nail varnish is to use a dedicated nail varnish thinner. These thinners are specifically formulated to be compatible with nail varnish ingredients, restoring the varnish to its original consistency without compromising its performance.
What to do if your nail varnish is thick:
1. Nail Varnish Thinner: Purchase a bottle of nail varnish thinner. Follow the instructions on the thinner bottle. Usually, this involves adding a few drops of thinner to the varnish, closing the bottle tightly, and rolling the bottle between your hands to mix the ingredients.
2. Warm Water Bath (Use with caution and sparingly): If you don't have thinner immediately available, you can try placing the closed bottle of varnish in a bowl of warm water for a few minutes. This can sometimes loosen up the varnish. Be careful not to get water inside the bottle. This is not a substitute for actual thinner.
In Summary: Avoid using white spirit or other household solvents to thin nail varnish. Use a dedicated nail varnish thinner for the best results.
