Product code: 46507015If your nail polish (including top and base) is not fluid enough, it should be diluted with Thinner, a solution specially formulated for this purpose. Never add nail polish remover or acetone as these solvents will cause the polish to separate and deteriorate. Check consistency of polish and add before commencing your manicure. If it is too thick, add a few drops of Thinner and roll the bottle vigorously between palms. Thinner should be added at least 20 minutes before use of polish and only if necessary.
