Ceramic Coating at Bologna Guglielmo Marconi (LIPE)

Why apply ceramic coating at Bologna rather than waiting for a scheduled maintenance stop?

Most operators think of ceramic as something you add during annual inspection, but the chemistry works best when you can control every variable—temperature, humidity, dust—and when the aircraft does not need to move for seventy-two hours. Bologna offers a dedicated general-aviation hangar large enough for an ultra-long-range airframe, H24 handling through TAG Bologna, and a location that does not require ferry positioning if you already work the Milan–Florence–Rome triangle.

We decontaminate the paint with a clay bar and chemical wash to pull out embedded particulate—runway rubber, exhaust soot, de-icing salts—then correct any oxidation or micro-marring with a single-stage polish. Only after the surface reads clean under a paint-depth gauge do we lay down the first ceramic layer. The second layer goes on twelve hours later, and the entire aircraft stays in the hangar for another forty-eight hours while the silica matrix cross-links. If you tried to do this on an open stand, a single rain shower or dust event would compromise the bond.

When the aircraft leaves, every future wash will take half the time, because contaminants no longer bite into the clear coat. For an aircraft flying two hundred hours a year, that difference pays back the ceramic investment in saved labour within eighteen months.

What changes at Bologna Guglielmo Marconi that affect a multi-day ceramic project?

Bologna sits at 123 feet elevation with a single runway—12/30, 2,803 metres—and operates around the clock without curfew. Three handling agents are present at the airport: TAG Bologna, Sky Services, and AviaVIP. TAG Bologna is the airport operator's own subsidiary and runs the Terminal Aviazione Generale, a 1,100 m² passenger facility with a dedicated 22,000 m² apron and the 2,000 m² hangar we use for ceramic work. They handle clearance, refuelling, and parking coordination twenty-four hours a day, which matters when your aircraft arrives late on a Friday and you want the decontamination wash started that same night.

Bologna moved from schedule-facilitated to fully coordinated status, so every arrival and departure now requires an Assoclearance slot. If you are blocking the hangar for five days, we ask for your outbound slot request at the time of booking so TAG can file it in one submission with the inbound. Missing a slot because the ceramic has not cured costs you another day and another clearance cycle.

The elevation and the Po Valley climate mean winter morning fog and summer afternoon convection. We have seen aircraft divert to Verona or Rimini, then reposition by road-crew van while the jet comes in an hour later. For a ceramic project, that delay is invisible—we simply start the decon sequence when the aircraft is on stand—but it does affect your passengers' ground-transport plans, so build contingency into the schedule.

What happens to paint and brightwork between Bologna and the rest of a European rotation?

Most jets we see at Bologna have just come off a Geneva–Nice–Bologna–Rome rotation, or they are positioning from a charter block in the Greek islands. Either way, the paint carries salt spray, bug strikes on the leading edges, and a thin film of Jet A vapour that bakes on under GPU exhaust while the aircraft sits on a sun-soaked ramp in August. If the jet also picked up Type I fluid during a Munich or Zurich departure in January, that glycol residue is still there, hidden under the next layer of dust.

Ceramic does not cover over contamination—it locks in whatever is underneath—so the decontamination phase is not optional. We clay-bar the entire fuselage, wings, nacelles, and tail, then follow with a solvent wash that pulls out embedded iron and organic residue. The polishing step removes oxidation and micro-scratches, bringing the paint back to the reflectivity it had when the aircraft left the completion centre. Only then does the ceramic go on.

Once cured, the hydrophobic layer means that the next time the aircraft lands in Bologna after a week of Mediterranean legs, the sea salt will rinse off with plain water. The brightwork—window frames, cheat line, winglets—stays cleaner, and you will not see the brown tide-line that usually appears along the belly after a winter of de-icing fluid and wheel-spray.

How do you schedule a five-day hangar block around charter or owner flights?

We ask for a minimum of three days and a maximum of six, depending on the size of the aircraft and whether we are also treating the belly and gear bays. The tightest window we have managed was a super-midsize jet that arrived on a Tuesday morning, went through decon and correction that day, received both ceramic layers on Wednesday, cured Thursday, and flew out Friday noon. That schedule works only if the aircraft is already clean—no heavy soiling, no oxidation that needs wet-sanding—and if the hangar temperature stays between fifteen and twenty-five degrees the entire time.

For most operators, a better plan is to combine the ceramic project with a cabin detail or an avionics upgrade that already requires downtime. If your interior shop needs four days to replace the divan leather and steam-clean the carpets, we can run the exterior ceramic in parallel and hand the aircraft back on the same day. TAG Bologna coordinates hangar access and GPU supply; we coordinate the work sequence with any other vendor on site.

If you have a charter block that cannot move, we can split the project: decon and first ceramic layer before the flights, then second layer and cure after the block ends. The first layer alone will give you sixty per cent of the hydrophobic benefit, and we finish the rest when the aircraft comes back through Bologna a month later. We do not recommend that approach for a new application, but it works for a maintenance top-up on an aircraft that already has ceramic from a previous cycle.

What documentation do you provide after the ceramic coating is complete?

Every aircraft leaves with a full photo report—before, during, and after—showing the decontamination results, the paint-correction passes, and the final ceramic application. The report includes paint-depth readings taken at a dozen locations around the fuselage, so you have a baseline for future inspections. If the aircraft goes to another detailer two years from now, that shop will know exactly how much clear coat remains and whether another polish is safe.

You also receive a maintenance plan that lists the recommended wash intervals, the approved cleaning chemicals, and the procedure for a top-up application. Most ceramic systems last two to three years under European operating conditions, but that duration assumes you are using a pH-neutral, non-abrasive wash soap and that you are not scrubbing the aircraft with a rotary brush at every turn. The plan spells out what will void the warranty and what will extend it.

The warranty document itself covers delamination, discolouration, and loss of hydrophobic effect within the stated period. It does not cover damage from bird strikes, hail, or improper cleaning by a third party. If you have a problem, we ask for photos and a description; if the failure is due to application error, we will re-do the affected panels at no charge during your next visit to Bologna or at any other airport where we can arrange hangar access.

Can ceramic coating be applied to an aircraft that has already been polished this season?

Yes, provided the polish was a single-stage correction and not an aggressive wet-sand. We measure the paint depth in six to eight locations before we begin; if the clear coat is thinner than 80 microns, we will not polish again—we go straight to a chemical decon and then apply the ceramic. If the paint is thick enough and we see micro-marring or haze from the previous polish, we do a very light finishing pass with a foam pad and a non-abrasive compound, just enough to level the surface.

The ceramic bonds to the clear coat through a chemical reaction, not mechanical adhesion, so the surface must be completely clean and free of any wax, sealant, or silicone residue. If the last detailer applied a carnauba wax or a polymer sealant, we strip it with a solvent wash before we start the ceramic process. That step adds half a day to the schedule but is not negotiable—any residue will cause the ceramic to peel within the first month.

If you are planning a repaint in the next twelve months, we recommend waiting until after the paint shop delivers the aircraft, then scheduling the ceramic as the final step before the jet returns to service. A new paint job gives us the thickest possible clear coat to work with, and the ceramic will protect that investment from day one. For an aircraft that was repainted two or three years ago and is starting to show oxidation, ceramic after a correction polish will bring the gloss back and hold it for another two to three years.
