To Serve and Protect

know how everyday issues relating to paint and varnish can be coped with and with manufacturers each claiming that their product can either cut emissions, boost performance or improve fuel economy, there is a lot more to the protection racket than just a chamois and squeezy blade.

Yachts live in some of the most corrosive conditions for paintwork in the world attacked constantly by high doses of ultra violet light and salt water. Paint surfaces are porous with millions of microscopic holes. Salt crystals get into these holes and act a little like the tip of a screwdriver boring away making the pores bigger. The sooner these salt crystals are removed the less damage is done. The less damage is done the smoother the surface and the smoother the surface the shinier the boat looks, as light is refracted in a focussed single beam rather than diffused in many directions.

Yacht detailing products and yacht cleaning supplies from the US based Sea-Shield have been developed over the years by experienced professionals working within the superyacht industry. Their Francisco Linares understands better than most, the task involved in yacht detailing and the importance of adding a protective barrier against the damaging effects of the sun and the sea. He says, “We developed products to make the crew’s life easier. When our products are applied maintenance time is substantially reduced. Future wash downs get easier every time Sea Shield is used and so insures the yacht has the best protection available.”

The application of ceramic protective coatings will seal the pores on paint, glass and stainless, preventing them from being damaged and creating an uneven surface that will never shine no matter how many wash downs are done. From the crew’s point of view, washing down a surface sealed with a smooth ceramic coating is quick and easy and results in the perfect shine. These specialist polymer and ceramic coatings enhance and protect the exterior paint surfaces against ultra violet, salt, dirt, exhaust fumes, oil and a host of other contaminates. Using a good polish can delay a paint cycle and if applied from new or whilst still in good condition can extend the life of the paint for years.

When discussing this with Andy Williams from CeraShield he explains “All our coatings have been especially formulated and engineered. With the harsh environments that superyachts find themselves operating in its essential to protect against harmful and damaging UV rays, soot and exhaust emissions, acid rain oxidation and salt deposits. Our next generation, premium Ceramic and Sio2 coatings can also restore and seal faded paint and gel coats. Once applied the ceramic coating forms a gas barrier which means no soot or exhaust emissions can penetrate the coating and leaves the surface with a slick, glass like finish that is very easy to clean and maintain without the use of aggressive chemicals and leaves the crew free to perform other important duties around the vessel.”

Isofan and Stoppani are paints made for the yachting market by the German Lechler Brand. Since 1883 Stoppani has dedicated special care to product quality and reliability. The product range they offer is continuously evolving using Lechler’s technological expertise with the aim of offering innovative paint processes to fully satisfy the different yachting segments’ needs. The Isofan Marine product range includes solid, metallic and pearl finishes of matchless gloss, light fastness and ageing resistance for yachts, pleasure and sailing boats.

The difference between a good paint job and poor one is always said to be down to the preparation. It is a cliché, but it is also true, that 99% of every good paint job lies in the preparation. It doesn’t matter if the finish is wood or fibreglass, the prep work still has to be done. This begins with removing all hardware, railings and decorative strips. Except where the complete removal of the object cannot be safely achieved the use of masking tape should be avoided. Before applying any coating, check that air conditioning units that vent on the area to be coated are cleaned or if possible that the fans have been turned off. It is a sad fact of life that the Sahara Desert is just too close to the marinas on the northern shores of the Mediterranean. That and the fact that superyacht docks are often close to roads, means that whenever crew are trying to paint a surface outside they encounter dust. Minute particles of sand or road grit are generally invisible to the eye but add a layer of wet coating to a surface and the annoying molecules of grit can quickly spoil hours of hard work. It’s a really good idea to use an air compressor to blow away dust from its surface and then to sprinkle clean fresh water on the deck, in the area being coated. This will help keep dust on the deck and help prevent it moving around in the air.

Kevin Viles recently sold out his fairing and painting company Concept Yachts Finishing brand to Finishing De Luxe in Germany and joined the board of the newly enlarged company as Commercial Director. Now with offices in the UK, Holland and Germany the company currently has five projects over 50 metres running simultaneously inside Heesen Yachts, along with two 90 metre refit projects underway at Royal Huisman.” Director Chasan Kalfoglou says, “For us it goes without saying that good preparation is one of the most important steps that we take on our projects. A high standard of preparation starts from day one and we maintain a high standard throughout the process.

These steps in preparation are crucial for the final result as poor preparation is easily spotted in the final top coat (gloss) and could easily compromise both manufacturers warranties and the overall finish of the vessel. The client expects a very high quality finish and as a standard we strive to provide this every time. Taking steps backwards on a project due to poor preparation is never efficient and extremely costly, so why risk it?”

Longevity, high gloss and easy cleaning are the standout features offered by a new class of coating made possible by recent advances in ceramic chemistry: Zytexx Clear-Coat. When using this revolutionary ceramic coating, salts, pollutants, acid rain streaks, oils and diesel soot are all easily removed. The hard, slick, abrasion-resistant finish does not wear down like waxes, polishes and polymers.

More importantly the product cuts crew cleaning time down to a fraction. By preventing diesel soot from permanently staining polyurethane paints, crew can avoid unsightly and expensive damage and eliminate the need to tediously polish out these defects. With its hard, scratch-resistant properties, fenders and hawsers mark Zytexx far less than paint. The company has supplied over 90 vessels in the Mediterranean alone all are using it to great effect. Captain Eddie West, in command of Sarafsa, is a big fan and has stated, “Zytexx has without doubt, extended the life of our paintwork to the extent where we have original paint of 11 years old in some areas. Glass readings were as low as 7 prior to using Zytexx and now readings are in the high 80s on this old paint. The application team are quick and efficient, just give them a cherry picker and leave them to it.”

Speaking for the company, Michael Pass says Captains should look out for Zytexx for glass surfaces. He says, “Our Glass Treatment restores salt pitted windows to clarity, greatly enhancing the look of your vessel. Treated windows become extremely water repellent; Water literally rolls right off eliminating spotting and reducing further etching. Even on windows fitted with wiper blades, Zytexx Glass Treatment provides long-lasting hydrophobicity.”

Nico Roper of Atlas Paint Consultants believes it is important before contemplating any large scale painting project, specialist firms such as his are called in. The job of a consultant should be to carry out a full pre refit paint status survey. Once that is done the consultant should prepare a bid book to reflect all the necessary requirements. Then he should have the yard and or the paint contractor prepare a paint manual. “It is vital,” he says, “to list the responsibilities and communication lines to make sure there are clear and open corporation between all parties”.

Painted surfaces that have a dappled look about them are often referred to as having an orange peel finish because of the texture of the surface after coating resembles the skin of an orange or grapefruit. This phenomenon is almost certainly the result of improper painting a technique, and can often be caused by fast evaporation of thinners or when using an incorrectly set up spray gun. It can also arise when a surface is painted with a roller using too little pain or too thick a paint so that the surface dries before the texture as a whole does so. When using a spray gun check the air pressure and ensure the correctly sized nozzle is fitted. Avoid spraying paint at an angle other than perpendicular to the surface and never apply an over excessive amount of paint.

When painting, it is always best to avoid extreme air quality or temperature conditions. Low temperatures will for example increase drying times while high temperatures will reduce drying times and can make application more difficult, as product flow and levelling is compromised. Optimal painting conditions are when the ambient temperature is between 10 - 26°C and relative humidity is below 65%.

It is always best to avoid painting in direct sunlight, or when the substrate itself is excessively warm. One good way to check this is to check the surface temperature using a specialised surface thermometer.

With over 20 years experience crewing superyachts, Duncan Sykes the Managing Director at Absolute Boat Care, understand absolutely the requirements and demands of captains and owners alike. Based in Mallorca, they have a large, highly professional team who have the capabilities to undertake absolutely any job, whatever the size. Captain Jason Lambourne, of the motor yacht Angara has enjoyed working with Absolute Boat Care and done so for the past four years. He says, “The products and the knowledge they employ when polishing Angara have always given her an incredible shine and made sure she is looking fantastic for her owners every season.”

When applying epoxies in high humidity conditions they can develop an ‘amine blush’ on the surface particularly at lower temperatures. This slightly sticky substance must be removed and can normally be washed off with soap and water. If the blush is not removed it can lead to the delamination of subsequent coats. High humidity conditions can reduce the amount of solvent evaporation during the drying/curing stages; with epoxies this can lead to a ‘soft cure’ where solvent can remain trapped in the film for many days leading to slow or poor final cure.

Patching paint is always tricky. There are some who say patching should always be thought of as a temporary repair because it will more than likely always be identified as such. Others believe that done well it is hard to tell if a patch repair has been made or not. It is a truism, however, that hard cut lines are almost always visible, especially in darker colours the likes of dark blues and blacks. They should, be avoided in areas where they are going to be very easy to spot.

It is of course imperative to use the same brand and colour as the original when trying to perfect the repair. One good tip is to keep a log of what is painted when it was completed and what product was used noting any batch numbers or identification codes shown on the tin. That way you know exactly what colour was originally used.

Some experts suggest it is best not to polish hard cut lines advising, hard cut lines will look worse than if they were simply left as they were. It is sometimes better to paint an entire section than a patch in the middle of a surface, as you would have less risk of it being visible. Larger areas are often better than smaller ones. Polishing out soft cut lines using specialist polishes is always the better solution. Certain paints can be polished and others cannot be polished, so be aware of what is possible before you start. A well polished patch when done properly will be almost invisible.

Based in Palma de Mallorca, Pure, headed up by Nic Clarke has painted over 20 superyachts in the 10 years the company has been in business project managing refits. He says, “I know a bit about paint and coatings but could not be regarded as an expert. That is why we always retain the services of a paint surveyor, sometimes much to the annoyance of the applicators working on the project. It was the project management style of the company that secured the responsibility of completely repainting the exterior of the 70 metre Lurssen built Saint Nicholas and it was perhaps because of the paint quality that this yacht exchanged hands so quickly one released onto the brokerage market.
