Dulux Marine Paint? - Comments Please

[BotleyBuoy]

I'm going to view a boat later in the week which the owner tells me was painted in a marine quality paint from Dulux. This was mixed at his local paint suppliers which supplies paint for marine use. This was applied to the hull above the waterline.

I wasn't aware that Dulux manufactured marine quality paint. I know from their website that supply PPG coatings. Has anyone come across this?

I've been told that below the waterline was painted with Tiger underwater primer and anti-fouled.

I suspect it was painted with a standard Dulux paint and the vendor had added the work 'marine' to fend of questions of bodging

The forum knows of many boats which use Dulux WeatherShield Textured as deck paint, and I can vouch for its effectiveness. I see no reason why their exterior gloss paints should be any less effective.

I have also successfully used Dulux Weathershield Gloss (not the water based stuff). Good durability and gloss retention.

I expect Seajet to contribute to this. I do recall that he has had great results with a particular Dulux product underwater, on a steel centreboard if I remember correctly.

I used Dulux Weathershield gloss on the topsides of the aluminium boat I used to have. It stood up to the rough and tumble of life in a commercial dock (Glasson) better than anything else I tried including International's Toplac and Brightside.

Dulux do not make paint aimed at the marine market. However some people use their paints because they are cheaper than those formulated for marine use and report success.

There is no such thing as Tiger primer. Blakes which has now been taken over by Hempel used to use the name for their basic antifouling, but the underwater primer was just branded Blakes. Would not get too worked up about it. The primer is a pretty generic formulation and most antifoulings can bee overpainted with new.

Many thanks for all the responses. I've checked my notes and it was Tiger anti-fouling applied over marine primer. Does that make sense now?

In terms of what was used as primer and undercoat on the hull above the waterline, what is "normal for marine use" (his words not mine) likely to mean? Is Dulux oil based primer and undercoat acceptable then? The planking is mahogany.

Delux in Europe is owned by Akzo Nobel, who incidentally also own International Paint. The Dulux brand is not marketed for the marine / yacht market, but that does not mean that their exterior paints will not perform satisfactorily in a marine environment. Rather bizarrely the Dulux brand in the United States is owned by PPG, again the brand is not marketed for marine sales.

If it is an old wooden boat it doesn't matter what it was painted with, sooner or latter you are going to take her back to wood and inspect it all. They you can select your paint of choice.

My mahogany beauty is adorned with Norteforte for the topsides, Epifanes for the bright-work and Tiger extra for the underwater stuff - along with a variety of poisons and potions that help the pretty stuff to stick to the wood properly.

I recently (August) had reason to ask Dulux's (AkzoNobel, that is) help system whether any of their paints would be suitable for painting a dinghy that would not be inthe water all the time. I got a categorical answer that Dulux did not make ANY paint suitable for marine use, and to look at International Marine.

So I've used Wilkinson's outdoor paint - it's supposed to last 6 years on the outside of a house, so I don't see why it won't do the same on a dinghy! Nothing lost if it needs re-doing in a year or two.

A +1 for weathershield for walkways. I did my first boat with all the la di da boat paints at some cost, and then realised that it was unnecessary, and ordinary gloss for top sides and weathershield for walkways for my current boat.

I have been involved in painting a fleet of six 19ft training keelboats with Dulux Weathershield Gloss prior to the 2016 season. They still look fine.

Did you add something to make the walkways non-slip?

When I had a house close to the sea, I found Dulux Weathershield noticeably more durable than other brands that I tried for exterior painting.
Separately, I was friendly with a boat-owning Scouser who told that Dulux was the normal boat-paint for many of his club-mates.

I had a load of "dust" to mix in, I'd got in store from when I was using overpriced posh paint.

Thanks.

I used Dulux gloss on a 31ft GRP hull and it gave a great finish and never needed repainting in the four years I owned her.

Yes, I have tried just about every paint & steel treatment going over 39 years with ( originally galvanised ) mild steel lift keel plates.

The treatment which has proven head and shoulders above the rest is Dulux Metalshield; it's a one part paint, but requires the particular one part Metalshield Primer, on bare or galvanised metal - it's the only stuff I've tried which looks as good at the end of season as when applied, when the boat was lifted at the end of the first season with it we exclaimed ' Wow ! '

However that's very different from using what sounds like household Dulux on topsides, which I must say doesn't appeal to me to even try, on my part chalked blue grp topsides I tried 709 epoxy but it went on like pudding, after that I sanded it smooth and now use Toplac with about 15% thinner for application in southern UK Springtime temperatures, this works well cosmetically and it is easy to touch up scrapes etc.

They will adhere to the wood and that is the right schedule of coatings. whether it stay stuck and the top cot lasts on;y time will tel. The difficulty with paint on traditional carvel hulls is that most have flexible seams which move as temperature and humidity changes. So it is the breaking of the paint film that leads to degradation and many old boats need annual seam filling and painting. If, however the planking is stable, for example if the construction is close seamed or splined the paint may last for several years.

The advantage of using proven marine systems is that they will hold their colour well and are easy to patch to deal with localised cracking or scuffs and scrapes. Keep on top of the maintenance and you can go several years between the inevitable strip back to bare wood. This is a lot of work but the material cost, even using the more expensive specialist paints is relatively low and worth it as a long term investment.

Tiger antifoul is a basic eroding formulation and can be overcoated with any of the current paints of similar type.
