Limestone Floor Tiles

We have been very expensive limestone tiles with a few months ago in our kitchen, and it has now received a small bump / hole in it to have something heavy falls on it. Outside of grout that show too, does anyone have good ideas on how to fix it without replacing the window?

If you have original tiles left over you can crush a small corner of a square and mix the dust with araldite clearly defined.

Apply it on the tile replacement to see how it looks when it goes down. If it looks good then do a little more dough and fill the Dent / hole.

Edit: apologies for the atrocious grammar, I think a coffee;)

Buy white portland cement, its a little more expensive, buy the black cement dye.
Mix a small quantity of white cement in a plastic bowl, add a small amount of dye to the cement mixture to achieve the desired color, apply the mixture stiff in the hole, now proud of the surface.
3 hours later shaved the rest.
Job done, DONT use sand, reducing the consumption of ordinary cement.
In the United Kingdom is called white cement Snowcrete.

Few cement and paint to match the mosaic.

If you still have the broken bits, filling the hole with them and cement again. It looks cool like that, a bit like something kind of mosaic. Thats what I did with tiles at low prices where I lived.

Mason here is a question for you
