How to apply a ceramic coating yourself
A full day, then a day of curing. £37–£165 in coating, clay, polish, shampoo and cloths.
Decontaminate, polish, strip the old wax, coat thin in small squares, buff at the right moment, keep it dry while it cures.

- Honest about when to call a pro
FIRST, THE HONEST ANSWER
Do it yourself, or get a garage?
Do it yourself if…
- You can work under cover in mild, dry weather for a full day
- The paint is in good condition, or you are prepared to polish it first
- You can keep the car dry and out of dust overnight while the coating cures
- You are happy to work slowly in small sections and check each in good light
Get a pro if…
- The paint needs heavy machine correction before it can be coated
- You want a professional-grade coating that is only sold to trained installers
- The car is matt, wrapped or has paint protection film
- You have nowhere sheltered and dust-free to let it cure
Safety first
- Wear nitrile gloves and work with good ventilation. Coatings and the panel-wipe fluids used before them contain solvents, and the safety regulator's valeting guidance warns that solvents can cause dermatitis and that their vapours can cause headaches, dizziness and nausea.
- Keep the coating off your skin and out of your eyes; wear safety glasses while applying it overhead on the roof.
- Read the safety data sheet and label before you start, put caps back on at once, and store the products cool, dry and out of reach of children, as the same guidance advises.
- Do not work inside a closed garage with no air movement; open the door or use a fan placed so it does not blow dust onto the wet coating.
- If you use a machine polisher for the preparation, keep the cable over your shoulder and the pad moving on the paint.
| MATERIAL | COVERAGE | FOR THIS JOB |
|---|---|---|
| Ceramic coating kit or spray | As the kit states per car | One kit for a family car |
| Preparation or panel-wipe fluid | Enough to wipe every panel | Usually in the kit |
| Clay or fallout remover | One car | One kit |
| Polish or scratch remover | One car | One bottle |
| Car shampoo | Label dose | One wash |
How many sections
Sections ≈ total painted area ÷ the section size. At about 0.5 × 0.5 m a section, each is 0.25 m²; a hatchback with roughly 10 m² of paint is about forty sections, and at 3–4 minutes each including buffing, around two and a half hours.
Work out your first section's flash time and use it as your guide; temperature and humidity change it.
A kit coating, applied by applicator and buffed, gives the longest consumer protection; the one we looked at claims up to one year. A ceramic spray or ceramic-infused wax is quicker and more forgiving, wiped on and off a panel at a time, but lasts less long. Choose a kit if you will do the preparation properly; a spray if you want a quick top-up.
Before coating, every trace of old wax, sealant and polish oil must come off, or the coating bonds to those instead of the paint. Kits usually include a preparation or panel-wipe fluid; the maker we looked at has you wipe the whole car with it in straight lines, turning the cloth often.
The coating seals in whatever is underneath, so swirls and bonded grit left on the paint are locked under it for a year. The coating maker recommends a fallout remover or clay bar and a polish or scratch remover for light marks before coating. This is most of the work.
Use the applicator the kit provides and several fresh, soft microfibre cloths for buffing. The maker we looked at says its coating has not been approved with other applicators. Keep the buffing cloths clean and separate; one contaminated cloth can drag grit across fresh coating.
Most consumer coatings are for paintwork and colour-coded plastics only. The one we looked at is not for glass, unpainted plastic or matt paint. Use a dedicated glass coating or trim product for those surfaces, and wipe any stray coating off them before it dries.
THE PART THAT DECIDES THE FINISH
Preparing the paint — by its condition
The coating locks in the finish underneath, so preparation decides the result. Find your paint below and do its list before you open the coating.
New or nearly new paint
Still needs decontaminating.
- Wash thoroughly with car shampoo and dry
- Use a fallout remover, or clay the paint, even on a new car; transport and storage leave bonded grit
- A light finishing polish is often enough before the panel wipe
Paint with light swirls
Polish first, then coat.
- Clay after washing until the paint feels glassy
- Polish out the swirls by hand or on a dual-action machine, working in small sections
- Inspect with a torch at an angle before you move to the panel wipe
Paint with deep scratches or failing lacquer
Coating will not hide it.
- Do the fingernail test on scratches: if the nail catches, polishing will not remove them
- Repair or touch up what you can before coating, or accept the marks will be sealed in
- Peeling lacquer needs a bodyshop before any coating
A car previously waxed or sealed
Strip it completely.
- Wash with a shampoo that does not leave wax behind
- Polish, which removes most of the old protection
- Wipe every panel with the preparation fluid in straight lines until no smear remains
Wheels, glass and trim
Different products.
- Mask unpainted plastic trim and rubber seals with low-tack tape
- Use a dedicated wheel or glass coating if you want those protected; most paint coatings are not for them
- Keep a cloth with preparation fluid handy to remove any coating that strays onto glass or trim
THE JOB
How to apply a ceramic coating
Set up under cover on a mild day
15 minWork in a garage or carport where the car stays dry and out of direct sun and dust, on a mild dry day within the coating's temperature range. Lay out clean cloths, the applicator and the preparation fluid, and go to the section above for your paint's condition.
- Check the forecast: the car must stay dry while it cures
- Sweep and damp the garage floor to keep dust down
- Set up the inspection light before you start
Mistake to avoid: Coating outdoors on a day with rain due. Water landing on uncured coating spots the finish and weakens the bond.
Wash and decontaminate
1 hourWash the car thoroughly with two buckets, wheels first and then roof down, and dry it. Use a fallout remover and rinse, then clay every panel with plenty of lubricant until the paint feels smooth. Dry the car completely, including the panel gaps.
- Feel the paint through a thin plastic bag to check it is smooth
- Fold the clay often; discard any that is dropped
- Blow or wipe water out of mirror housings and gaps
Mistake to avoid: Skipping decontamination on a car that looks clean. Bonded grit is sealed under the coating and stays there for its whole life.
Polish out swirls
2–3 hoursPolish the paint panel by panel to remove swirls and light marks, by hand or on a dual-action machine, using the least aggressive product that works on a test spot. Buff off and inspect each panel under the light before moving on.
- Small sections and slow passes
- Ease off near edges and body lines
- Mask trim before polishing
Mistake to avoid: Coating unpolished paint. Every swirl under the coating looks sharper and glossier — and is now locked in.
Strip with the preparation fluid
30 minApply the preparation fluid to its cloth, not the paint, and wipe every panel to be coated in straight lines, turning the cloth often so it does not saturate. Wipe away any residue with a dry part of the cloth. This removes polish oils, old wax and fingerprints so the coating bonds to bare paint.
- Every panel, including lower sills and behind the handles
- Turn and change cloths often
- Do not touch the paint with bare hands afterwards
Mistake to avoid: Coating over polish oils. The coating bonds to the oil film, and it washes away within weeks.
Do a test section
10 minOn the first panel, apply a small amount of coating to the applicator and spread it in straight, overlapping lines over a section about 50cm square, without overloading. Watch it closely: when it forms small beads and begins to film, buff it off. Time how long that took, and let that first panel set the pace for every panel after it.
- Thin coat; too much makes high spots
- Time the flash on this first section
- Buff gently, then with a fresh face of the cloth
Mistake to avoid: Guessing the timing for the whole car. On a warm day the coating flashes in a minute or two; leave it and it hardens into a smear.
Coat the car section by section
2 hoursWork round the car in a fixed order, one section at a time, applying thin straight overlapping lines and buffing each section at the flash time you found. Add small amounts of coating to the applicator as needed. Start with the roof and work down so you never lean over a freshly coated panel.
- Overlap sections slightly so there are no gaps
- Change to a clean buffing cloth when the current one feels grabby
- Keep a fixed order so no panel is missed or double-coated
Mistake to avoid: Coating several panels before buffing. By the time you get back to the first, it has cured too hard to level.
Inspect and fix high spots
20 minWhen the car is done, move the light — or the car — to see every panel from different angles, and look for dark, oily-looking patches or streaks, called high spots. Buff any you find straight away. If one has already hardened, the maker we looked at says to apply a little more coating over that small area and buff immediately. If you can, ask a second person to look along the panels too; fresh eyes catch the streaks you have stopped seeing.
- Look from low angles along each panel
- Check the edges, the lower doors and around badges
- Remove any stray coating from glass and trim with preparation fluid
Mistake to avoid: Leaving high spots to find in the morning. Once fully cured they need polishing off, which removes the coating there too.
Let it cure dry and clean
4 hoursLeave the car under cover, out of the rain and away from dust, for at least the minimum cure time on the label — 4 hours for the coating we looked at — and ideally overnight. Then do not wash it for the time the label says, 24 hours for that coating.
- Keep it dry overnight if you can
- Avoid dusty roads or parking under trees during the cure
- Do not wash for at least the first day
Mistake to avoid: Driving off into the rain straight after coating. Water spots set into the uncured coating.
Clean the applicators and cloths
15 minWash the applicator and finishing cloths as the maker says — the one we looked at says at 30 degrees with detergent only and no fabric softener, colours kept separate — or discard single-use applicators. Cap and store the remaining coating as its label says.
- No fabric softener; it clogs microfibres
- Keep coating cloths separate from wax cloths
- Note the date you coated the car
Mistake to avoid: Washing coating cloths with fabric softener. They smear afterwards and are no use for buffing.
The mistakes that show
- Coating unpolished or contaminated paint, sealing the swirls in
- Skipping the preparation wipe, so the coating bonds to old wax
- Applying too much, or buffing too late, leaving high spots
- Coating in the sun or on a damp, cold day
- Letting the car get wet before the coating has cured
Stop here and get a ceramic coating installer
- The paint needs heavy machine correction, or you are unsure how much clear coat is left
- You want a professional-grade, multi-layer coating sold only to trained installers
- The car is matt, wrapped or has paint protection film
- You cannot keep the car dry and dust-free while it cures
| WHAT YOU SEE | WHY, AND THE FIX |
|---|---|
| Dark, oily-looking patches after coating | High spots: coating left too thick or buffed too late. Apply a little more coating over the area and buff immediately; once fully cured, they need polishing off and the area recoating. |
| Streaks visible in sunlight | Uneven application or a saturated buffing cloth. Buff with a fresh cloth while still possible; otherwise polish lightly and recoat that panel. |
| Water no longer beads after a few weeks | The coating bonded to old wax or polish oils, or was washed too soon. Strip with polish and preparation fluid and recoat. |
| Water spots set into the finish | Rain or sprinkler water landed during the cure. Try a quick detailer; etched spots need light polishing and recoating. |
| Swirls more visible after coating | They were there before and the coating made them stand out. Polish them out and recoat the panel. |
| Coating on the glass or black trim | It was not wiped off before drying. Remove with the preparation fluid at once; once hard, a glass polish or trim cleaner helps. |
| The protection fades well before a year | Harsh detergents, brush car washes, solvent products or polishing wear it away. The maker we looked at says to avoid strong alkali pre-sprays and solvent products, and to recoat areas where they were used. |
| The surface holds water rather than shedding it | The coating is wearing out. The maker we looked at treats water sitting on the cleaned paint for over a minute as the sign to reapply. |

Two buckets, a pH-neutral shampoo and a microfibre towel. Avoid brush car washes and strong alkaline pre-sprays, which shorten the coating's life.
A compatible ceramic spray or wax every few months boosts the finish. Recoat any area where you have used a polish or solvent product.
Take unwanted coating, preparation fluid and solvent products in their containers to your council's household waste and recycling centre, which accepts household chemicals within limits; empty aerosols go in the aerosol recycling. Wash water goes to a foul drain, never a road drain, because only clean water belongs in surface water drains.
When the cleaned paint starts holding water instead of shedding it, the coating is wearing out; the maker we looked at treats water sitting on the cleaned paint for over a minute as the sign.
Applying a ceramic coating: questions people ask
The kit coating we looked at claims up to one year of protection if the instructions are followed. Ceramic sprays last less. Harsh detergents and brush car washes shorten either.
Yes, if the paint has swirls or marks. The coating seals in whatever is underneath, and the maker we looked at recommends removing light scratches and swirls before coating.
The coating we looked at needs at least 4 hours to cure away from rain and dust, and the maker says not to wash the car for 24 hours.
Only on a mild, dry, still day out of direct sun, and only if the car can stay dry while it cures. The maker we looked at gives an ideal range of 10–25°C.
Patches where coating was left too thick or buffed too late, which look dark or oily. Apply a little more coating and buff straight away; once fully cured they need polishing off.
The Locufy UK price guide puts professional ceramic coating at £200–£1,500 per application, typically £500 — the same three figures as the strip at the top of this page.
