Marble is a delicate stone that can become damaged fairly easily. You can repair a marble floor without spending thousands. A marble floor is very expensive and replacing it isn't always in the cards or the budget. The only recourse you can take is to repair the marble floor by patching any chips or chunks from the marble. It seems much harder than it actually is and the article below will show you how to easily repair the marble floor.
Step 1 - Prepare the Marble Floor Surface
Since the marble floor is already chipped this means you do not have to remove the finish like you would to repair scratches. You do not even have to wipe down the floor. There is some minimal preparation required since you still have a hole in your marble floor. Inside the hole will most likely be loose marble which will need to be removed in order to make the patch adhere. Use a brush to dust out the bits of rock in the hole and to remove any loose pieces from the hole of the site. Use the miniature vacuum to suck up the debris. Use the tack cloth to remove the dust away from the perimeter of the hole.
Step 2 - Replace the Chunk
If the chunk of marble still remains then you may be in luck. Marble does not usually crumble and depending on how the hole was made you will be able to replace it. When you want to repair a marble floor in this manner, you will need to use adhesive formulated for marble or stone. Apply some of the adhesive to the hole and some to the piece then place it inside the hole. Press it down and wipe away any excess adhesive.
Step 3 - Fill the Hole
This is the easiest method to repair a marble floor that has a chunk taken out of it and is missing. Make sure that the hole has been fully cleaned and prepared prior to filling the hole with epoxy. Use an epoxy that comes in two parts and mix them in a clean bowl according to the directions. You will have to work quickly before the epoxy starts to set. Spoon the epoxy into the hole with the spoon until it overflows the edges. Use the putty knife to spread the epoxy out and this will also push the epoxy all the way inside the hole. Wet down a rag and remove the excess water and use it to wipe around the edges of the hole. This will remove the excess epoxy so that the edges are flush to the marble floor.
Step 4 - Finish
After the epoxy has cured you can seal the spot using polyurethane. Pour a very small amount of polyurethane in a plastic bowl. Apply it over the epoxy using the micro brush.
