How do you fix a hairline crack in a cultured marble sink?

Moreover, what causes cracks in cultured marble?

The cracks sound like a condition called “crazing” which occurs when the gel coat fails and allows water to work its way into the cultured marble. If the sinks are old, the gel coat can fail simply because of constant use and age. So avoid exposure to either scalding-hot or icy-cold water.

Also Know, how do you fix hairline cracks in marble? Since most marble has variegated color, it is easy to disguise repair jobs. When dealing with a hairline crack, use a clear epoxy to fill in the gap and sand it smooth afterward with a fine-grit sandpaper. If the repair is too obvious, use a colored wax stick over the top to blend with the marble color tones.
