Thread: Goat Island Skiff (Chile) - Construyendo un pequeño bote de madera en Chile

Thanks Mik.

Today Mr. Luis Oteiza (Professional boatbuilder) visited my boat, and he said it was ok.
I´m very glad.
At the moment I have done 2 layers of epoxy and fiberglassed the borders.
There is another layer of epoxy to go.
I have done some sanding to the borders of the fiberglass.
The advice from Mr. Oteiza was to prime the boat with a mass done with a soft talk (Talco Martelina) and the same pain to be used later on (two component acrilic paint). He ussualy does 3 layers and sanding in between to fill any gap, and then paint with aerograph - air brush.

Lets see how it goes.

Saludos,

JC.

Thanks for the update Juan Carlos,

Sometimes it is difficult to get the acceptance of more traditional boatbuilders ... so even the gentle support from Mr Oteiza is happily accepted!

Congratulations.

Best wishes
Michael

Thanks Mik, I think his advice regarding the primer should be fine, isn´t it?

Cheers.

JC.

Sounds fine.

As you glassed the bottom, does a little bit of sanding create a smooth surface or does the weave of the fibreglass cloth prevent you from sanding it smooth?

I am guessing Mr Otieza is suggesting the talc because the weave is not filled.

If the weave is not filled epoxy and talc will help you fill it. There are better things than talc though you may have trouble getting them in Chile, I think.

Main point is once the boat is smooth, it is time to undercoat and paint.

It is nice if the undercoat is white. The aim is to put undercoat on and sand it to get a very smooth even surface, and also to get it evenly white (it will probably take more than one coat) before the final gloss paint is added.

Best wishes (Saludos)

Juan, Do you have epoxy and microballoons filler? I could give you a very slick way to get that bottom prepped faster than you can say lickity-splittiliy-wittly.

Clint

Hi guys,

The only thing available is the talc, I guess I have to use it with epoxy before the primer?

Cheers,

JC

If your local boatbuilder uses it, then I can't see any particular problems. It will be OK for filling. The surface will need to be sanded first.

Most of the filling powders ... don't make good glues at all because they need to be weak enough to sand easily afterwards.

Hola Juan Carlos !

Thanks Juan for your log of your building. I've been reading it with great interest as I am getting ready to start building my GIS.

Question for Clint: Does the Le Tonkinois varnish block UV? In all other respects it appears to be a great product, I'd just hate for my epoxy underneath to degrade for lack of UV protection.

Any varnish with superior durability will have good UV filters.

What normally happens is as the UV filters run out the timber underneath the varnish starts to break down and that is when the varnish starts breaking down.

As Tonkinois has a reported high durability it will have high UV filters too. Remain to see how it behaves in OZ though. We see a lot of european varnishes break down quite quickly on imported boats. I used to have a nice sideline in adding extra coats of new varnish to almost new Beneteaus.

Rick, It is a great for UV's. The Le Tonk #1, a more refined varnish, has better UV blocking.

I love this stuff. I don't use a lot of varnish on my boats, and the little I use is always this stuff now. You can also buy a Linseed Oil wax...this is good for maintaining the surface over time. I'd order from www.solventfreepaint.com

Back from winter...

I´m about to end the winter break on boatbuilding... the weather is slowly getting better and wamer, so I will have time to finish up the hull form ouside.

I think the Poliuretane varnish I´m using does have UV protection and is easy to find.

Well, I´m taking this week off and I hope to have time to update the building diary.

By the way, my second daughter was born a month ago and we have move to a new house, another two good reasons wy I have to take time from boat building this winter...

Cheers,

JC.

Hi Rick, good luck, I´m sure you´ll enjoy boatbuilding.

Let me know If I can be of any help.

Cheers,

Congratulations, Juan, on the birth of your daughter! Very exciting!

And welcome back to your boat building project. Looking forward to seeing your continued progress.
