Cracking Finish on Marble Table

by W. Norman Stovall
(Riverdale, GA)


I have a seven-foot marble dining table the finish has long cracks.

I have lifted a piece of the finish off the table. It looks like plastic of some sort.

How can I repair this problem. Can I fill the exposed marble with polymer resin? Thank you.


It sounds like you have some type of coating on the marble that is now old, degraded, cracking and coming off.

Permanent topical coatings and waxes should not be used on natural stone. This is a good example why.

I'd suggest using this De-Greaser / Wax Remover / Stripper to remove the old coating.

Chemical coatings and wax used to be applied quite often in an attempt to reduce maintenance and/or change the shine or look of the stone, but most often these coatings add little benefit and create more problems (and maintenance) then they were meant to solve.

Topical conditioners and polishes can be used to enhance the shine, but such products (the good ones anyway) don't form a film and are only temporary... they wear off with use and cleaning.

As much as possible you want to leave any stone in a natural state.

Applying a marble & granite sealer is often beneficial, but this does not change or affect the look or performance of the stone (except to drastically slow down absorption of staining liquids) since the sealer works below the surface.

The problem with coatings and waxes is that they cover the surface, so now you have a layer of something that is not stone. The required maintenance is then dictated by the needs of the coating and not the stone.

And is some instances a coating can actually cause the stone to decompose by not letting it breath.

Many mistakenly believe the shiny marble surface comes from applying some type of product or "finish".

When speaking of marble the "finish" is part of the stone and not something put on the stone. The "finish" refers to the type of surface treatment given to the stone... meaning a shiny "polished" finish or a more dull but smooth "honed" finish or a somewhat rough "tumbled" finish, etc.

The various types of finish are created on the stone itself with different physical methods. A finish can be worn away from use, foot traffic, but it's not going to "come off" like a coating will. Learn more about how to polish marble (click here).

You need to strip off whatever is on the marble surface, see what shape it's in and go from there.

Who knows what the marble surface and finish will be like once removed, but it may need nothing more than a good marble cleaning.

If it is a polished (shiny) finish, then you may want to tune up the shine using the Marble Polish / Etch Remover.

This product's primary purpose is to repair dull etch marks, but it works equally well to spruce up an uneven or slightly worn polished finish (but not on a honed finish).

Scratches in the marble surface can be polished out effectively using the above products as well.

Marble Table Top Crack

by Robert


I have a marble coffee table with cracks in the finish... not in the stone. I do believe it is real stone not cultured. What to do to repair this cracking.


Let's first clarify what is meant by the "finish" when speaking about natural stone. The finish is actually part of the stone itself.

However, you state that the marble table has "cracks in the finish... not in the stone".

This clue likely means that you have some type of coating that was once applied on top of the marble.

Yes, in other applications such a coating would be considered a "finish", so I explained to make clear the difference with natural stone.

The marble table surface finish is not "applied" or "put on" the stone. The "finish" on any stone whether honed or tumbled or flamed or polished is simply a matter of working the stone with tools and abrasives to get the effect you want.

For example a shiny "polished" marble finish is made by intense friction using special abrasives to wear the stone into a smooth, mirror-like finish.

Generally marble polishing of large slabs is done on specialized industrial machines. Your table was likely made from such a slab.

It may have become dull at some point due to marble etching and someone put a coating on it attempting to make it shiny again.

When polishing stone manually it's a lot like sanding wood only much more difficult to do well.

If you do have a true crack, it is in the stone. It may not be all the way through the full thickness of the stone, but in the stone nonetheless.

Of course, you could have a scratch, which if severe enough you could see and feel. And you could have an old coating or wax that is now dried out and cracking.

What to do? ...

Well, if a scratch, you can likely repair it (on polished marble) using the Marble Polish / Etch & Scratch Remover, which is excellent for removing light to medium scratches.

If indeed the stone is cracked, you'll need to consult a marble repair pro to stabilize the stone.

However, often cracks may be present, but do not get worse. If the crack has a lip, then that will be a problem and you'll need to hire a pro.

If you can feel the crack, but no lip you may be fine just leaving it alone.

You really can't "repair" a crack. Not in the sense that it will look new again.

Sometimes the pieces can be removed and then glued together and put re-installed. But usually it's a matter of stabilizing and supporting the stone so the crack doesn't get worse.

Cracking in an worn top coat or wax is solved simply by removing the coating.

Marble Crack getting larger
by: David

I have two similar cracks in my marble tabletop. I also feel it is in the surface as when I look at the "crack" I actually see about 1/2 inch of lighter material on either side as if the surface coating is lifting off the marble. Much like you would get when water starts getting under a coating. There is a definite edge to the crack when you run a finger nail across it. I don't see any depth to this crack other than the very thin veneer layer of the coating, if that is what it is. This crack has gotten wider over time, as measured with the distinctive. The marble is the traditionaly all black with white striations throughout.

Marble Care For Cracks & Stains

by Glenda G.


I have these marble bathroom sink and countertops. The sink parts have stains and cracks that are just from 30+ years of use.

I can afford to change them or have a professional do it. I was told when we put them in that these can just be buffed out.

What can I do to fix these problems? Thanks!


Marble stains can be removed by following the step-by-step instructions in the Removing Stains Manual.

Cracks are a different matter and it depends on the type. Are these actual cracks in the stone or possibly cracking of a surface coating or even just scratches?

You can't really "buff out" a true crack in the stone. If the crack is large and there is separation, then you could perhaps apply polyester glue like Akemi to fill and or support the area, but obviously you can't "remove" a crack. Even when repaired it will always be visible.

So, this is something I'd have a marble repair and restoration professional look at.

Now if these "cracks" are actually scratches, then yes.... they can be repaired using ETCH REMOVER / Marble Polishing product (link above) to buff them out on a "polished" (shiny finish) marble surface.

Cracking of a coating is another issue entirely. Waxes and surface coatings get old and dry and can show cracking, scuffing and/or discoloration.

Waxes and coatings are not commonly used anymore and should not be. They create more maintenance issues than they solve.

However, if this is the case with your marble countertop, then the coating itself must be stripped off the surface using the Deep Clean Stripper / Degreaser (see link above).

Once the wax / coating is removed, then you can assess the true condition of the marble vanity.

For the sinks... if the stains and cracks are in the sinks themselves, I'd consider just replacing them unless they are particularly unique.

Again, if the sinks are marble the stains can be removed just like on a marble countertop (unless very deep and old) and scratches (not cracks) can be removed with the paste.

This would be cheaper than replacing the sinks or professional marble care, but it all depends on how severe the damage is.

I'd start with the above DIY solutions and then call in a pro if necessary.
