Re: Faux Teak and Deck Paint

Joel,
 
   Many thanks for giving us the final word on how  the grooves in the Amel deck were originally gel coated  in the mold.  It is amazing to have input from someone that was actually at the factory when some of these amazing boats were built.   I now better understand why you were so impressed with the work that the “gals” did in painting these stripes!  Besides somehow cutting a straight line and holding the required thickness, they had to be very careful avoid any drips onto the rest of the prepared mold.  I would never have had the patience myself.   I will never look at my deck quite the same again.  (grin)
 
Thanks Joel,

Hi Mark and Cindy. I saw this process in action many times over the years. The “grooves” between the faux teak planks are recessed on the finished deck. On the mold they are quite proud of the planking. The dark brown of the “ grooves “ are the first thing to be done well before the brown of the deck is applied over. This dark  brown gel coat, I was told, had a wax component that surfaced and supplied a barrier against the atmosphere for proper curing. The brown gel coat of the decking was applied on top of the grooves/very dark brown gel coat.
 
I might add that the gals doing this process were very skilled and experienced at this process. They also had incredible focus and would not respond to conversation while doing this.
 
Having restored the plank separating gel coat with gel coat by brush and also the paint method by the striping tool, you will achieve better cosmetic results with the striping tool, especially the first few times you do it until you acquire some skills.
 
Hope this is helpful.
 
All The Best, Joel

James,
 
I feel very enlighten. Thank you. However, a question still nags me. If the deck stripes were applied by the French ladies of Amel, did they do it in the mold so the underside of the deck stripes were exposed to air, or did they paint the stripes once the decks were removed from the mold? If it is the latter, then the products and technique used by Amel seems like it would be the option to go with. 
 
 
With best regards,

Mark,
 
   That is not a stupid question, in fact it is a great one!  It is certainly possible to recoat gelcoat with new gelcoat.  In general however it is important to understand that the gelcoat used for boatbuilding are “air inhibited cure”.  This means that the exposure to air prevents a full cure so the surface remains soft and tacky.  This is a benefit when boatbuilding since this increases the bond between the gel coat and the layers of fibreglass being added.  The gelcoat against the mold itself cures nice and hard since air is excluded. So there are additives that can be used with regular gelcoat or coatings that can applied allow the gelcoat to fully cure.  One is simply a wax additive which floats to the surface and helps exclude the air, another option is to spray the fresh gelcoat with PVA which is poly vinyl acetate, it just forms a film over the gelcoat to exclude the air. You can just wash the PVA off with water later after the gel coat is fully cured. There are also some specialty additives that you can purchase from major suppliers of polyester resins, some of which work well when patching gelcoat.  So you want to use one of these options to help your gelcoat cure properly on the surface if you are using regular boat building type gel coat.  There are also non air inhibited gel coats and I have used one called Simtec Prestec which can be tinted to any colour.  The material cures hard as glass without any additives but for some reason the UV resistance is inferior. I have never looked into the reason but there could be other non air inhibited gel coats that have better UV resistance.  New gelcoat will bond pretty well to old gel coat if you really roughen up the surface and do not have any contaminants on the surface.  60-80 grit would not be too coarse.  I am absolutely sure that if done correctly that gel coat will outlast any one part paint and possibly even the two part paints.  Unfortunately gel coat is not too easy to brush on.   So you have to apply it smoothly since It does not self level like paints do..  Adding some styrene thinner can help with brushing some but mostly you need to apply it as smooth as possible via your technique.  The good thing with the gel coat is that if you have thick or uneven spots you can come back and sand and polish out those areas but what a lot of work that would be if you had a lot of them!  So yes, this is actually an excellent idea IMO.
 
Best,
 
James

If the original deck striping was done with tinted gel-coat and brushed by hand, then why does nobody use this option to recondition the deck stripes. After all, the gel-coat applied by the French ladies of Amel lasted a very long time. Having never really done much work with gel-coat other than the occasional patch, I don’t really understand why this would be a non-option. If someone could enlighten me, that would be appreciated.
