Konig uPVC Scratch Repair Kit

Konig Window Doctor Scratch Repair Kit — uPVC Window & Door Filler Kit (6 Hardwax Shades)

Repair scratches, chips and dents in woodgrain, foiled and coloured uPVC windows and doors in minutes — six hardwax shades, no replacement panel required.

Konig Window Doctor Scratch Repair Kit (MPN KO614206) solves the problem every homeowner dreads: a deep scratch, chip or dent in an otherwise perfectly good uPVC window or door. Replacing a marked panel or frame section is expensive and disruptive, yet the damage itself is often no bigger than a coin. This professional-grade uPVC repair kit uses heat-applied hardwax filler to fill, level and blend damage so the repair disappears into the surrounding surface. Important before ordering: this kit contains six dark and woodgrain shades only — Black, Dark Oak, Golden Oak, Irish Oak, Rosewood/Mahogany and Anthracite Grey. There is no white or light hardwax in this kit, so it is not suitable for standard white uPVC frames.

Konig is a name used and recommended by professional installers and repair technicians worldwide, and this is the same specification kit they carry in the van. Everything arrives in a protective carry case: a battery-operated heating iron with three AA batteries supplied, a shaped application tool, a cotton cloth for finishing, six 4cm hardwax filler blocks and detailed step-by-step instructions. As well as uPVC, the hardwax works on composite doors, foiled and laminated finishes, and timber windows and doors.

Key Benefits for uPVC Door and Window Owners:

• Saves the Cost of a Replacement Panel or Frame – A single scratched door panel or damaged frame section can run into hundreds of pounds once labour is added. This kit repairs that same damage for a fraction of the price, and there is enough hardwax in each 4cm block for dozens of small repairs around the house.
• Six Woodgrain and Coloured Shades to Match Your Frames – Black (9005), Dark Oak (143), Golden Oak (49601), Irish Oak (90096), Rosewood/Mahogany (114) and Anthracite Grey (78516) cover the most common woodgrain, foiled and coloured uPVC finishes fitted across the UK. Shades can be blended together to fine-tune the match to your exact frame.
• Heat-Applied Hardwax Fills and Levels Properly – Unlike touch-up pens that simply paint over damage, melted hardwax flows into the void and sets hard, so the repair is level with the surface rather than sitting on top of it. That means no shadow line, no catching a fingernail on the repair, and a finish that stands up to being cleaned.
• Works on Composite Doors and Timber Too – The same hardwax and technique repairs composite doors, foiled and laminated finishes, and timber windows and doors, so one kit covers the whole property instead of just the uPVC.
• No Specialist Skill or Trade Experience Needed – The heating iron, application tool and detailed instructions are all included, and the process is fill, level, wipe back. If you can use a glue gun, you can use this kit — and the satisfaction of putting the damage right yourself is part of the appeal.
• Ready to Use Straight Out of the Box – Three AA batteries are supplied for the heating iron, so there is no hunting through drawers or a trip to the shop before you can start. Unpack it, fit the batteries and get on with the repair.
• Protective Carry Case Keeps Everything Together – The moulded case stores the iron, tool, cloth and every wax block in one place, so the kit is still complete and usable the next time a scratch appears — which, with children, pets, ladders and wheelie bins, it will.
• Restores Kerb Appeal and Protects Resale Value – Chipped, gouged frames make a house look tired and neglected from the pavement. Tidying up the damage brings frames back to an almost factory-fresh appearance without the upheaval of replacement.
• Seals the Damage Against Moisture and Dirt – Open chips and gouges trap grime and hold water, which makes the mark more obvious over time and can accelerate deterioration on timber and laminated surfaces. Filling the void closes it off and keeps the repair looking clean.
• Trade-Grade Product at DIY Prices – This is the professional Window Doctor kit, not a watered-down consumer version, so the results and the durability match what a repair technician would achieve on the same job.

Please check the colour of your frames before ordering. This kit is designed for woodgrain, foiled and coloured frames. If your windows or doors are standard white uPVC, this kit will not colour-match your frames. If you are unsure which shade suits your finish, contact us with a photo and we will be happy to advise.

Pro Tips:

Pro Tip: Woodgrain uPVC is rarely one flat colour — most foils run two or three tones. Rather than reaching straight for the single closest block, melt a small amount of two shades together (Golden Oak warmed with a touch of Dark Oak is a common match for standard Golden Oak foil) and test the blend on a hidden area first, such as the bottom of the frame behind an opening sash or the inside face of a door edge. Clean and fully dry the damaged area before you start, overfill very slightly, then level and wipe back with the supplied cotton cloth while the wax is still warm — trying to trim a cold, hardened repair is what pulls the filler back out of the void.

Frequently Asked Questions:

Will this kit repair a scratch on my white uPVC window?
No — this kit does not contain a white hardwax block. The six shades supplied are Black, Dark Oak, Golden Oak, Irish Oak, Rosewood/Mahogany and Anthracite Grey, so it is designed for woodgrain, foiled and coloured frames rather than standard white uPVC. Please check your frame colour before ordering; if you have white frames, contact us and we will point you towards a suitable alternative.

Can I use this on a composite door or timber windows, or is it just for uPVC?
It works on all of them. The hardwax and heat method suit uPVC windows and doors, composite doors, foiled and laminated finishes, and timber windows and doors, which makes it a practical single kit for a whole property. The same shade-matching advice applies whatever the substrate.

How do I match the hardwax to my exact frame colour?
Start with the closest single block, then blend in a small amount of a second shade to fine-tune the tone — most woodgrain foils contain more than one colour, so a blend usually reads better than a straight match. Always test on a concealed area such as the underside of a frame or a door edge before working on a visible face.

What tools do I need and is it difficult to use?
Everything needed is in the box: the battery-operated heating iron, the application tool, a cotton cloth for finishing and printed instructions. Three AA batteries are supplied, so no extra purchases are required. The method is straightforward — melt, fill, level and wipe back — and is well within reach of anyone comfortable with basic DIY.

How long does the repair last and can I clean over it?
Hardwax sets firm and bonds into the damage rather than sitting on the surface as a paint or pen would, so a properly levelled repair stands up to normal cleaning and weather exposure. Avoid aggressive solvents or abrasive pads directly over the repair and it will stay looking sharp.

How many repairs will one kit cover?
Each shade is supplied as a 4cm hardwax block, and a typical scratch or chip uses only a very small amount of wax. For everyday household damage you can expect a great many repairs from a single kit, and the carry case keeps the remaining blocks clean and usable for next time.
