Corian and solid surface worktops are among the most premium surfaces found in modern kitchens — and among the most misunderstood when they are damaged. Most general tradespeople will not touch them. Kitchen fitters will quote for replacement. And DIY attempts with household abrasives or automotive cutting compounds almost always make the damage worse.

Solid surface repair is our second core specialism. With 20 years of hands-on experience working exclusively on kitchen worktops, we carry dedicated Corian repair and polishing systems to every job — restoring cracked, scratched, burnt, and dulled solid surface worktops to a seamless, factory-smooth finish on-site, without replacement.

We cover Surrey, Hampshire, and Berkshire from our base on the Surrey and Hampshire border.

Why Corian Can Always Be Restored

Corian and solid surface materials are homogeneous — the colour and composition run consistently through the full 12mm thickness of the sheet. There is no surface veneer to lift, no coating to strip, and no pattern that cannot be recovered. This means that unlike laminate, stone, or timber, virtually any damage to a solid surface worktop can be mechanically restored rather than replaced.

Scratches, burns, cracks, chips, and staining all sit within a material that can be abraded back, re-levelled, and re-polished to match the surrounding surface — provided the process is carried out correctly with the right equipment and the right abrasive sequence.

The key word is sequence. Corian restoration is not sanding. It is a precisely controlled progressive abrasive process that must follow a strict grit order to achieve a finish that is flat, consistent, and free of haze. Cutting corners in the sequence — or using the wrong abrasives — leaves swirl marks, uneven sheen, and localised low spots that are immediately visible on the finished surface.

Our Corian Repair & Restoration Services

1. Crack Repair

Cracks in Corian worktops are almost always structural — caused by thermal expansion around hob cutouts, impact stress, or movement along poorly supported joins. They are also one of the most common reasons homeowners are told they need a full replacement. In the vast majority of cases, they do not.

Our crack repair process follows the only method that produces a genuinely invisible, structurally sound result. We use a 2100-watt router fitted with precision Titman router bits to cut an inverted trapezoid channel along the full length of the crack. This undercut profile is critical — it creates a mechanical key that locks the repair material in place permanently rather than simply filling the surface.

The repair material itself is cut from the customer's own spare Corian piece — the off-cut left by the original installer, which most customers keep as a chopping board. This is not a convenience. It is the only reliable way to achieve a colour match. Corian is manufactured in batches, and batch variation means that even an apparently identical sheet bought from a supplier will show a visible colour difference under kitchen lighting. Using the customer's own material eliminates that risk entirely.

Once the insert is bonded in place using Corian-branded adhesive, we use a customised laminate router fitted with a precision sled jig to flush the repair perfectly level with the surrounding surface. The abrasive sequence then brings the repair zone into a seamless, uniform finish.

2. Chip Repair

Edge chips and impact damage on solid surface worktops are repairable without replacement in almost every case. Using the same material-matched insert approach as crack repair — sourcing the repair material from the customer's own spare piece where colour matching is critical — we rebuild the damaged profile and blend it back into the surrounding surface through our progressive abrasive sequence.

3. Scratch Removal

Fine surface scratches are the most common complaint we receive about Corian worktops, and the most straightforward to resolve. Daily use from cookware, utensils, and crockery introduces thousands of microscopic abrasions that collectively dull the surface and give it a tired, aged appearance.

Scratch removal is carried out using our Mirka DEROS with a full Mirka Abranet sequence — working progressively through 80, 120, 180, 240, 320, and 400 grit before finishing with Mirka Abralon to restore a consistent satin sheen across the entire surface. Every stage of this process is connected to our Makita M-Class dust extractor, keeping composite dust out of your kitchen throughout.

The result is a surface that is uniformly flat, consistently finished, and indistinguishable from the original factory surface.

4. Burn & Scorch Repair

Placing a hot pan, baking tray, or heat gun directly onto a solid surface worktop exceeds the thermal threshold of the acrylic resin, leaving scorched, yellowed, or blistered marks on the surface. In our experience, Corian burn marks are never severe enough to require material removal — they sit within the upper layers of the surface and respond consistently well to abrasive treatment.

We address burn damage using exactly the same progressive Mirka Abranet sequence as scratch removal, working through the full grit range until the thermal discolouration is fully abraded away and the surface finish is restored to a uniform sheen across the affected area and the surrounding surface.

5. Stain Removal & Surface Restoration

Although Corian is a non-porous material, prolonged contact with harsh household chemicals, bleach, dyes, or certain food acids can etch or chemically mark the upper surface layer. These marks respond well to mechanical abrasion — our progressive Abranet sequence removes the affected layer without altering the flatness of the worktop, restoring a clean, consistent finish.

Integrated Corian sinks are included in our restoration service. Staining, scratching, and surface dulling in Corian sink bowls are treated using exactly the same abrasive process as the surrounding worktop surface.

6. Full Surface Polishing

Over time, even undamaged Corian surfaces lose their original factory sheen through daily use. Our full surface polishing service uses the complete Mirka Abranet and Abralon sequence to restore a consistent, uniform finish across the entire worktop — removing years of surface wear and returning the material to its original appearance.

We can polish Corian to a range of finishes from satin through to high gloss. However, we routinely advise customers against high gloss finishes on kitchen worktops. The glossier the surface, the more visible every fine scratch becomes in daily use. A satin finish is more durable in appearance, easier to maintain, and in our experience the finish that ages best in a working kitchen.

Our Equipment & Abrasive System

Achieving a factory-quality finish on Corian requires a specific combination of equipment and abrasive discipline that most general tradespeople do not carry.

Mirka DEROS Random Orbital Sander

Our primary polishing and resurfacing tool for all Corian work. The DEROS is used with Mirka Abranet ceramic mesh abrasives through a full progressive sequence — 80, 120, 180, 240, 320, and 400 grit — before finishing with Mirka Abralon pads. This sequence is non-negotiable. Skipping grits or rushing the progression leaves haze and swirl marks that are immediately visible on the finished surface.

Makita VC4210M M-Class Dust Extractor

Every tool on every Corian job is connected to our Makita M-Class extractor. Composite acrylic dust is a hazardous airborne particle. Our extraction system captures it directly at the tool head throughout the entire process, keeping your kitchen clean and the air safe.

2100-Watt Router with Titman Router Bits

Used for inverted trapezoid crack channelling and precision cutout work. Titman router bits are specified for their dimensional accuracy and clean cutting profile in solid surface material — critical when the channel geometry determines the structural integrity of the repair.

Customised Laminate Routers

We run two dedicated laminate routers for Corian work. One is modified with a precision sled jig for flushing crack and chip repairs perfectly level with the surrounding surface. The second is fixed to a router table for controlled edge and profile work.

Track Saw

Used for precision straight cuts when sectioning repair material from the customer's spare Corian piece.

An Honest Note on Colour Matching

Corian is manufactured in batches, and batch variation is real. Two sheets of apparently identical Corian can show a visible colour difference under kitchen lighting — enough to make a repair immediately obvious if the wrong material is used.

This is why we never source repair material from a supplier sheet. We always work from the customer's own spare piece — the off-cut left by the original installer. If you no longer have your spare piece, we will assess the colour match situation honestly before we begin and advise you on the best approach.

In the majority of cases where the customer's own material is available, crack and chip repairs are genuinely seamless. Where it is not available, we will tell you what is and is not achievable before any work begins.

Frequently Asked Questions

Can any Corian worktop be repaired, or are some beyond saving?

In our experience, virtually every Corian worktop can be restored rather than replaced. Cracks, chips, burns, scratches, and staining all sit within a homogeneous material that responds consistently to mechanical restoration. The only scenario where repair becomes genuinely difficult is where the customer's spare material is unavailable for a crack or chip repair and the batch colour variation between available sheet stock and the installed surface is too significant to blend invisibly.

Why does my Corian worktop keep cracking around the hob?

Cracks around hob cutouts are almost always caused by one of two things — insufficient thermal expansion clearance left during installation, or sharp 90-degree internal corners on the cutout rather than radiused corners. Sharp internal corners create stress concentration points that split under repeated heating and cooling cycles. We repair the crack and where possible introduce a correct radius profile to reduce the risk of recurrence.

Can I use Cif or other household abrasive cleaners to remove scratches myself?

No. Household abrasive cleaners and automotive cutting compounds like T-Cut create uneven localised low spots and destroy the uniform factory sheen — leaving a permanently hazy, cloudy patch on the surface. Achieving a flat, consistent finish requires a controlled progressive abrasive sequence with professional equipment. There is no DIY shortcut that produces the same result.

Do you restore Corian integrated sinks as well as worktops?

Yes. Integrated Corian sinks are treated using exactly the same abrasive process as the surrounding worktop surface. Staining, scratching, and surface dulling in the sink bowl all respond to our Mirka Abranet and Abralon sequence in the same way as the worktop itself.

How long does a Corian restoration take?

It depends on the scope of work. A full surface polish on a standard kitchen layout typically takes a full day. Crack or chip repairs involving routing, insert fitting, and abrasive finishing take longer and may require a two-visit process depending on adhesive cure times. We will give you a clear time estimate when we assess the job.

Is high gloss polishing available?

Yes, we can polish Corian to a high gloss finish. However, we advise against it for kitchen worktops in regular use. A high gloss surface shows every fine scratch from daily kitchen activity far more readily than a satin finish. Most customers who ask for gloss reconsider when they understand how quickly it will show wear. Our standard recommendation is satin — it is more durable in appearance and ages far better in a working kitchen environment.

Aftercare: Keeping Your Restored Corian Surface in Good Condition

Corian is one of the lowest-maintenance worktop materials available when treated correctly. Following a few simple guidelines will keep your restored surface looking good for years.

What to do:

Clean daily with a mild, pH-neutral surface cleaner and a soft cloth. For routine maintenance, a cream cleaner such as Corian-approved Handy Andy applied with a soft cloth in a circular motion will keep the surface clean without dulling the finish.

What to avoid:

Never place hot pans, baking trays, or heat guns directly onto the surface. Always use trivets or heat pads. Avoid prolonged contact with harsh chemicals, bleach, or strong acids — while Corian is non-porous, sustained chemical contact will mark the upper surface layer. Do not use abrasive scouring pads or household cutting compounds — these will scratch the surface and dull the finish unevenly.
