We had some recent work done on our house and it appears that one of the workers nicked the vinyl flooring in the kitchen -- resulting in a circular gash about 3/4 inch wide. Here's a picture:
Unfortunately the contract we had with them indemnify them against stuff like this so we'll need to repair it ourselves.
The good news is that we're eventually planning to replace the flooring (probably within the next year). In the meantime, I looking for a way to repair the damage and make it resistant to water.
