Scratch and coating loss
We check whether the mark is superficial or exposes the substrate. We select the surface preparation and touch-up system for the specific coating.
Cladding repair for
sandwich panels.
Let’s start with a proper assessment.
A scratch, a dent or damaged coating on the cladding of an industrial building? We repair insulated sandwich panels, also known as composite panels, on industrial and warehouse buildings. From your photos, we assess whether a spot repair is enough and propose the method and scope of work. If a repair does not make sense, we tell you so plainly and explain what other scope needs to be considered.
Panel Cure+ is a Panel Montage brand.
Method and price after assessing the specific case.
What has happened
to the panel?
A mark from a tool, an impact on the facade, chipped paint? You don’t need to know how the repair is done. Choose what you see and show us the damage.
Show the scratch and the area around it.
Take one photo close up and one from further away. If you can, add a scale, e.g. a ruler, and note whether bare steel is visible.
Go to the enquiry formThese are enquiry categories. The type of damage alone does not determine whether a spot repair is possible.
We match the repair
to the specific panel.
The RAL colour is only the starting point. The right method also depends on the coating type, the sheet profile, the depth of the damage and the condition of the core.
Show us your panel →Localised dent
We assess the deformation of the sheet, its profile and the area around the damage. We check whether the surface and the paint finish can be restored.
Deeper panel damage
A crack, an exposed core, or a damaged panel joint or fixing requires a broader assessment. Before quoting, we establish whether a localised repair is enough or whether replacement is needed.
First, we establish what can be done.
Not all damage qualifies for spot repair. The condition of the facing and the core, the location of the damage and the manufacturer’s requirements all matter. The repaired coating may differ in shade: we discuss the expected result before work starts.
Coating repair
in five stages.
Spot repair, i.e. localised repair of the factory coating, repairs transport and installation damage on sandwich panel facades without removing the panel, provided the damage qualifies for localised repair. We developed our work standard with Pro-Painter Academy.
- 1
Diagnosis
We identify the type of factory coating (polyester, PVDF, HDX) and assess the depth of the damage.
- 2
Cleaning and activation
We degrease the surface with coating-safe products and prepare it so that the repair coating adheres well.
- 3
Rebuilding
We restore the geometry of the sheet, fill areas of material loss that expose the PIR/PUR core and protect exposed steel.
- 4
Refinishing
We spray a two-component topcoat enamel matched to the RAL shade and gloss level, and blend the transition using the spot repair method.
- 5
Quality control
We assess the repair under varying lighting angles and, where the order requires it, measure the coating thickness (DFT) and carry out an adhesion test.
Adhesion
Surface preparation and activation reduce flaking of the repair coating, including on demanding factory coatings such as PVDF and HDX. We check adhesion with a cross-cut test to EN ISO 2409.
Colour and gloss level
We match the shade using the RAL scale, in solid and metallic colours, and adjust the gloss level with matting agents.
Transitions without a visible edge
We work zone by zone and blend the paint transition on panel ribs and edges.
Protection of the exposed core
We rebuild areas of material loss that expose the PIR/PUR foam, and protect exposed steel with a primer before applying the new coating.

Installation experience.
Refinishing precision.
We are developing our know-how in sandwich panel coating repairs on real samples and cases from construction sites. Dedicated training combines knowledge of installation with techniques for localised surface repair, colour matching and finishing.
On 24-25 October 2026, our team completed training prepared for Panel Montage by Pro-Painter Academy at the NOVOL Training Centre in Komorniki: the 16-hour certification programme “Spot Repair of OEM Coil Coatings on Sandwich Panels”. The training was led by lead trainer Robert Grząślewicz.
The academy is run by its owner, Dr Tomasz Tomczyk. We prepared the programme with him around the problems of sandwich panels: from tests on coatings and damage analysis to establishing which cases are suitable for localised repair. See the team’s certificates ↓

Training completion certificates
Three members of our team successfully completed the 16-hour Pro-Painter Academy certification programme “Spot Repair of OEM Coil Coatings on Sandwich Panels” (Komorniki, 25.10.2026).
Programme scope (16 hours)
- Health and safety and personal protective equipment for repair and painting work on industrial buildings and facades.
- Identifying factory coatings: polyester, PVDF and HDX; assessing the depth of transport and installation damage.
- Substrate preparation: selecting coating-safe cleaners and degreasers and abrasive paper grades, sanding and feather-edging the damaged areas.
- Rebuilding material loss: filling areas that expose the PIR/PUR core and restoring the geometry of the sheet.
- Protecting exposed steel and adhesion: protecting exposed sheet metal and primers that improve adhesion to factory coatings (PVDF, polyester).
- Colorimetry and gloss level: matching the colour on the RAL scale and adjusting the gloss level with matting agents.
- Spraying technique: setting up HVLP and RP spray guns, nozzle selection and application practice.
- Spot repair and blending: blending the transition zone on panel ribs and edges, in solid and metallic colours.
- Quality control: assessment under varying lighting angles, coating thickness measurement (DFT) and adhesion tests.
The certificates were issued by Pro-Painter Academy. They confirm that the named individuals completed the training; they are not a product certificate or a guarantee of the result of a specific repair.
Colour and finish
We are developing our skills in assessing shade, gloss and blending. We want to match the finish to the existing surface, its age and the viewing conditions. The RAL number is a reference point; the result requires an assessment of the specific coating.
Surface preparation and repair
We practise substrate preparation, working on localised defects, restoring the profiling and applying coatings. Selecting fillers and the paint system requires compatibility with the substrate and defining the limits of each repair.
Informed assessment
Knowing a technique also means recognising its limits. Coating damage, deformation of the facing and damage to the core each require a different assessment. Where there are doubts about the panel’s properties, input from the manufacturer or the designer is needed.
From tests to practice
A good colour match is only half the repair.
In preparing the programme with Pro-Painter Academy, not only the appearance but also the adhesion of the new coating was tested. The tests showed that the inner and outer faces of a panel can react differently to the same preparation method. That is why we select the method for the specific surface.
After the preparation was changed, a better cross-cut adhesion test result was obtained on the samples tested. This is a valuable pointer for selecting the technology; the result of such a test is not a long-term durability test or confirmation of the performance of the whole panel.
How much repair material?
First we assess the damage and select the filler, primer and finish. Layer thickness and mixing ratios depend on the specific product and the substrate. Filling a dent does not in itself establish the condition of the core or the panel joints.
Further training in colorimetry and material selection is intended to develop this precision: from identifying the coating to defining the result we can propose to the client.

We come and carry out the repair
Once you accept, we carry out the agreed scope. We sign off the work and document the result achieved.
We know panels. We know construction.
Sandwich panel walls and roofs, flashings, cold stores and freezer rooms. We know a panel together with its joints and its place in the whole building envelope.
We work with main contractors, construction companies and developers. We install walls and roofs of industrial buildings, cold store and freezer room enclosures and partitions for technical rooms. We combine installation experience with organising crews on international projects.
Panel Montage Sp. z o.o. has been operating since 2025. The people behind the company were already gaining experience before it was founded, working on construction sites across Europe. We base our specialism on this experience.
We are developing Panel Cure+ as a service for localised panel surface repairs. The company’s installation background helps us take a broader view of the damage: to check its position relative to a fixing, panel joint, flashing or opening. A photo of a scratch alone is not always enough to decide on the solution.
Before work starts, we agree the scope, method, access to the repair area and the expected result. If the damage requires a broader assessment, we say so before quoting. We do not replace a technical assessment with a promise that every panel is suitable for spot repair.
We got to know panels
on construction sites first.
Panel Montage’s background helps us assess not only the mark on the coating but also its position relative to a joint, flashing or fixing.
Panel walls and roofs
Installing sandwich panels as the envelope of industrial buildings and warehouses. Working with panel layouts, fixings and joints.
Flashings and details
Corners, base flashings, reveals and parapets. Elements that close the envelope and require precision on site.
Cold stores and freezer rooms
Installing panel chambers and partitions. Also cleanrooms, and enclosures and partitions for data centre areas.
Facades and substructures
Facade cladding together with its substructure. We agree the scope, documentation and method of execution for each specific project.
How do we organise
Panel Montage work?
From documentation to handover. We tailor supervision and reporting to the specific contract.
- We review the project
We check the country, documentation, installation scope and programme. We establish what information is needed for the quote.
- We agree responsibilities
We define the scope boundaries, access to the work front, materials, equipment and coordination rules.
- We prepare the crew
We match the crew to the tasks and timescale. Before mobilisation, we confirm the working conditions and site requirements.
- We deliver the scope
We install in line with the documentation and agreements. We document changes to the scope and agree them with our partner.
- We close out the works
We agree the handover and the final account for the completed work. The documentation method follows the project conditions.

repair scope.
We repair wall and roof panels on industrial buildings, warehouses and other industrial facilities. We take on roof work after assessing access and the conditions for carrying it out safely. We assess damage from photos and, where necessary, during a site survey.
Repair or replacement? See how we assess it →What the repair covers
We work on the panel facing and coating: localised dents, creases with a damaged surface, scratches and dark scuff marks, and coating damage, including where there are several on one panel. During the repair, we assess and make good the joint sealing in line with the panel manufacturer’s system. A deformed flashing usually has to be replaced. Sandwich panels are also called insulated panels or composite panels and, depending on the core, PIR panels or mineral wool panels, for example.
Localised repair, not the whole facade
We work at the point of damage and in its immediate surroundings. We do not paint or clean entire walls and roofs: this is not part of our offer. Where the coating is ageing over a large area or there is a great deal of damage, we say so before quoting and explain what other scope needs to be considered. We do not repair single-skin trapezoidal or profiled metal sheets: Panel Cure+ works on sandwich panels.
Damage during construction and before handover
Scratches and dents also occur after the panels have been installed, when other trades are working on site. We help main contractors before the building is handed over: we assess the damage, describe it with photos and locations, and identify which areas qualify for localised repair. Such a description makes it easier to agree the scope of work before handover. We know panels from installation, so we also look at panel joints, fixings and flashings.
What determines the cost of sandwich panel repair?
We quote after assessing the specific damage, not upfront per square metre. The price depends mainly on the damage, the panel material and the site conditions. You don’t need to know all the technical data: show what you can check safely, and we will establish any missing information when we talk.
- Material and coatingManufacturer, panel model, RAL colour and coating type, if known.
- DamageNumber, size, type and depth of the damaged areas. Send a close-up photo with a scale and a wider shot showing the location on the wall or roof.
- Site conditionsWorking height, travel and access to the repair area, and how the work is organised on site.
- Scope for approvalMethod, achievable result, price and timescale before the repair starts.
Let’s start
with a photo.
Take a close-up of the damage and a photo from further away. Give the town, country and a short description. You don’t need to guess the manufacturer, colour or coating type: if you don’t know them, just say so.
What is worth showing?
- The damage close up, in good light.
- A wider shot showing its position on the panel.
- The extent of the damage and access to the work area.

Before you get in touch
Can every panel be spot-repaired?
Not every case is suitable for this kind of repair. The damage, the substrate and the working conditions need to be assessed. In some situations, replacing the element or a different scope of work should be considered.
How much does sandwich panel repair cost?
The price depends on the number, size and type of damaged areas, the panel coating, the working height, travel and access to the repair area. For an initial assessment, prepare a close-up photo with a scale, a wider shot and the site location. Photos help define the scope; sometimes a site survey is needed. We agree the price and proposed method before work starts.
Are photos enough to decide on the repair?
Photos help with initial screening. Choosing the method may require additional information about the panel, the manufacturer’s documentation or a site survey.
Will the repair be invisible and will the manufacturer’s warranty be preserved?
This cannot be promised for every panel. The result depends on factors including the coating, its condition and the extent of the damage. The repair conditions and any effect on the warranty must be established for the specific case.
Is the RAL number alone enough to match the colour?
Not always. The type and condition of the coating and colour changes caused by weathering in service also matter. Photos and manufacturer data help with the assessment, but final decisions may require a check on site. A difference in shade is possible.
When is replacing a sandwich panel better than repairing it?
If the panel joint or the core is damaged, or the facing is punctured or deeply deformed over a larger area, a localised repair will not usually restore the panel’s function. A deformed flashing is also usually replaced. We decide after assessing the photos and, where necessary, after a site survey. How we assess repair and replacement.
How long does a sandwich panel last?
There is no single figure for all panels. Manufacturers link durability to the coating system, the corrosivity category of the environment, the colour and regular inspections, and the warranty period is not the same as the service life. Damage that exposes the steel is worth reporting promptly, as corrosion can start there. We have collected manufacturers’ data in our guide.
Can a sandwich panel be painted only where it is damaged?
Yes. We refinish sandwich panels locally, as part of the repair: after assessing the coating and preparing the substrate, we refinish the damaged area and blend the transition into the surrounding coating. The shade of the repaired area may differ from the ageing factory coating, so we discuss the expected result before work starts. We do not paint entire walls, facades or roofs.
What should you do after an impact on a sandwich panel facade?
Take a close-up photo, ideally with a scale, and a wider shot showing the location on the wall. Mark the location, e.g. with the gridline or door number, and cordon off any sharp edges. Do not sand, straighten or paint the damage yourself, as this will make the assessment harder. Then send your enquiry. What to do, step by step.
How should sandwich panel joints be sealed?
It depends on the system of the specific panel manufacturer: joint sealing is matched to that system, so there is no single sealant for every panel. When we repair a panel, we assess the joints at that point and make good the sealing as part of the service. We do not claim that the whole envelope is watertight. If leaks keep coming back, the cause needs a broader assessment, not just another layer of sealant.
Do you repair sandwich panels on roofs?
Yes, repairing roofs made of sandwich panels is part of our scope. We decide on roof work after assessing access and the conditions for carrying it out safely; these also determine the method, timing and price. At the repair point, we check the joints with the adjacent panels and make good the sealing. We do not claim that the whole roof is watertight, as the repair covers the damaged area. Take photos from the ground or another safe position: do not go onto the roof just to take them.
Is your team trained in paint repairs of sandwich panels?
Yes. In October 2026, three members of our team completed the 16-hour Pro-Painter Academy certification programme in localised paint repairs of factory coatings on sandwich panels. See the certificates.
What do manufacturers recommend?
The repair should follow the documentation for the specific product. There is no single recipe for all panels and coatings.
Ruukki · SPA panels
The instructions describe touch-up of damaged coating and repair of small dents. When refurbishing the surface, substrate preparation and checking the adhesion of the old paint are important.
Ruukki documentation ↗Kingspan · minor repairs
The instructions distinguish superficial scratches from damage reaching the substrate. They recommend keeping the touch-up area small (its shade may differ from the factory coating) and entrusting the work to specialists.
Kingspan instructions, p. 51 ↗Before the repair, we establish the requirements for the specific panel model and coating, and the effect of the work on the warranty. Citing these instructions does not mean that Panel Cure+ is authorised by the manufacturers.
