How do I fix a crack in tile without replacing them?

I don't know if you can do it with removing it. You may try to insert super glue of tile grout to fill the crack.

Hi Ann, this looks like a great link, good luck :)

Actually I’ve been doing a lot of research on that very topic. The tile industry will say the only thing you can do is completely crack up the broken tile and replace it.

However, I’ve been really looking at all the breathtaking applications and uses of Epoxy Resin. I’ve found because it is basically a glue that hardens into a glasslike smooth surface, it can also be used to repair holes and cracks. With the addition of mica, pigment powder or paint it can even add sparkle to a bland surface.

The following site is using this application on wood and gave me the idea to try this with tile:

This link talks about repairing/ painting tile with epoxy Resin:

I’ve also found through YouTube that Leggari seems to have the easiest epoxy to apply and work with.

I plan to test this idea on a spare piece of tile once I’ve gathered some more materials. Currently researching the pigment powders and mica dust options I can apply for pop.

Hope this helps and have fun expressing your God given DIY creator talent.
