Tips

  • This method works best on glazed tiles. Avoid using it on porous tiles.
  • Use separate brushes for mixing the nail polish to avoid color contamination.
  • For deep chips, multiple applications of wood glue and nail polish might be necessary.

Common Mistakes to Avoid

1. Using the wrong type of wood glue

Reason: Not all wood glues are created equal; some are too thick or don't adhere well to ceramic.
Solution: Choose a thin, strong wood glue specifically designed for ceramic or porcelain.

2. Applying too much glue or nail polish

Reason: Excess glue can squeeze out and create a messy, uneven finish, while too much nail polish can smudge or become too thick.
Solution: Apply a small amount of glue and nail polish, spreading it thinly and evenly.

3. Not allowing sufficient drying time

Reason: Rushing the drying process can lead to the repair weakening or failing completely.
Solution: Allow ample drying time according to the product instructions before applying weight or pressure to the repaired tile.

FAQs

Will this repair be noticeable?
While this method is excellent for concealing minor cracks, very large or deep cracks might still be slightly visible. The color match of the nail polish to the tile is crucial for minimizing visibility. Perfect color matching isn't always possible, but a close match will significantly reduce the noticeability of the repair.
