Marble Worktop Repair
Specialist Marble Repair, Etch Removal & Polishing Across Surrey, Hampshire & Berkshire
Marble is the most demanding worktop material we work on, and the least forgiving of the wrong repair method. It is softer and more porous than granite or quartz, which means it marks more easily — but it is also a natural stone, which means damage sits within a material that can be filled, levelled, and polished back to a genuine match rather than simply patched over.
Most kitchen fitters treat marble damage as a replacement job, largely because they do not carry the resin, tinting, and polishing equipment required to restore it properly. We do. With 20 years of specialist worktop repair experience across Surrey, Hampshire, and Berkshire, we restore cracked, chipped, stained, burnt, and etched marble worktops on-site, without removing the worktop and without the cost of replacement.
Why Marble Behaves Differently to Granite and Quartz
Marble is calcium carbonate. That single fact explains almost everything about how it fails and how it must be repaired. Granite and quartz are largely inert to household acids — marble is not. Any acidic liquid — lemon juice, vinegar, wine, fizzy drinks, many household cleaning sprays — reacts with the calcium carbonate on contact and dissolves a microscopic layer of the polished surface. This is acid etching, and it is a chemical reaction, not a stain. No amount of cleaning will remove it, because the gloss layer itself has been chemically altered.
Marble is also more porous than granite or quartz, which makes it more susceptible to staining from oils, wine, and pigmented liquids that would sit on the surface of a denser stone. And because it is a natural, veined stone rather than a manufactured surface, colour and vein matching on any repair has to be done by eye, on-site, rather than sourced from a spare off-cut.
None of this makes marble worktops harder to repair — it makes them a different repair to granite, quartz, or Corian, requiring a different diagnostic approach before any tool touches the surface.
Our Marble Repair Services
Crack Repair
Cracks in marble are structural and need to be treated as such before any cosmetic work begins. We fill the crack using Tenax Vinyl Ester resin, applied in stages rather than as a single pour — on any crack with meaningful depth, filling in 2 to 3 layers significantly reduces shrinkage and the risk of the fill cracking again as it cures. Each layer is left to cure before the next is introduced.
Colour matching is done manually, on-site, using solvent-based tints mixed to match the specific bed of marble in front of us — there is no off-the-shelf colour code for natural stone, and no two slabs are identical. Once cured, the resin is levelled and flushed using sharp razor blades, working the fill down flush with the surrounding surface without disturbing the surface polish either side of the repair.
Chip Repair
Marble chips are repaired using exactly the same process as our granite and quartz chip repairs — Tenax Vinyl Ester resin, colour-matched and applied on-site, is the only filling product we use. There is no separate bulk filler. Deeper chips are built up in layers in the same way as crack repairs, to control shrinkage as the resin cures.
Once cured, the repair is flushed level using razor blades and brought back into the surrounding surface through our polishing sequence, below.
Acid Etch Removal
Etching is one of the most common calls we get on marble, and the one most homeowners misdiagnose as a stain. Because etching is a chemical change to the surface polish rather than a contaminant sitting on top of it, no cleaning product will remove it — it has to be mechanically re-polished out.
We work the etched area through our full polishing sequence, starting at whatever grit is needed to remove the depth of the etch — light etching from a splash of lemon juice may need very little, while a heat-and-acid combination or a long-standing etch mark will need to start coarser. The surface is then carried back up through the full grit progression to restore the original gloss level.
Stain Removal
Marble's porosity means stains from oil, wine, coffee, and other pigmented liquids can sit below the surface rather than on it. Surface-level staining is removed through the same mechanical polishing sequence used for etching. Where staining has penetrated more deeply into the stone, we assess on-site — in most cases mechanical polishing resolves it, and where a stain has penetrated further than polishing alone can reach, we will tell you honestly what result to expect before we start.
Burn Mark Repair
Direct heat from a hot pan or dish can scorch the surface polish on marble in the same way it discolours Corian, though marble is generally more heat-tolerant than solid surface. Burn marks are ground out and re-polished using the same progressive sequence used across all our marble work, working through the affected area until the discolouration is gone and the finish matches the surrounding surface.
Full Surface Polishing
Marble worktops dull with age and daily wear — from acid etching accumulated over years of use, general abrasion, and loss of the original factory gloss. Our full surface polishing service brings the entire worktop back through the complete grit progression, restoring a uniform, consistent gloss level across the full surface rather than a single patch.
Our Polishing Sequence
Marble polishing follows the same progressive philosophy as our Corian work, but the sequence continues considerably further, because marble is refined to a genuine mirror gloss rather than a satin sheen.
We work through Mirka Abranet ceramic mesh abrasives at 80, 120, 180, 240, 320, and 400 grit using our Mirka DEROS random orbital sander, connected throughout to our Makita VC4210M M-Class dust extractor. From 400 grit, we move onto tungsten carbide polishing discs and continue the progression through 600, 800, 1000, 1500, and 2000 grit. Each stage removes the fine scratch pattern left by the one before it — skipping a stage leaves haze that the following grits cannot fully remove, so the sequence is followed in full on every repair.
The result at 2000 grit is a genuine mirror finish, matched to the surrounding polished surface rather than left as a visibly separate patch.
An Honest Note on Marble Repair
Marble is a natural material, and every slab is different. On crack and chip repairs, we colour-match by eye on-site, and while the result is very good in the vast majority of cases, an exact, invisible match cannot be guaranteed in the way it can on a homogeneous material like Corian, where the repair material comes from the same manufactured sheet.
Etching and staining respond very well to mechanical polishing in most cases. Where staining has penetrated deeply into a heavily porous area of stone, full removal cannot always be guaranteed, and we will tell you honestly what improvement to expect before any work begins.
We do not carry out marble repairs we cannot stand behind, and we will always assess your specific worktop and give you a realistic outcome before starting work.
Frequently Asked Questions
Do I need to replace my marble worktop if it has cracked?
In most cases, no. Marble cracks are filled using Tenax Vinyl Ester resin, colour-matched on-site and applied in stages to control shrinkage on deeper cracks. The repair is then flushed and polished back into the surrounding surface. Replacement is rarely the only option.
Why does lemon juice or wine leave a mark on marble but not on granite or quartz?
Marble is calcium carbonate, which reacts chemically with acidic liquids. Granite and quartz are largely inert to the same acids. The reaction dissolves a microscopic layer of the surface polish — this is called etching, and it cannot be cleaned away because it is a chemical change to the surface itself rather than a contaminant sitting on it.
Can etch marks be removed without repolishing the whole worktop?
Yes, in most cases a localised area can be re-polished through the full grit sequence and blended into the surrounding surface. For worktops with etching spread across multiple areas from years of general use, a full surface polish usually gives a more even, better-value result than several patch repairs.
Will a stain come back after you've removed it?
No, provided the source of the staining is addressed. If a stain has penetrated deeply into a porous section of the stone, we will tell you honestly what level of improvement is achievable before starting, rather than guaranteeing full removal we cannot deliver.
How long does marble repair take?
A localised crack or chip repair, including resin cure time, typically requires a single visit with the repair curing while we are on-site or a short return visit depending on the depth of the fill. A full surface polish across a complete worktop run usually takes a full day. We will give you a clear time estimate when we assess the job.
