May 10 - "To Remove" turned into "To Build up" - First GRP experience
Till now, the main word of my project was "remove", from now on, the main work will be "re-build". Most of the work to do is to cover some holes and reinforce the structure, as the junction deck-hull. In the back of my car I carried 16meters of mat and roven as also 10 liters of resin to start the buiding enterprise ! A bit overdimensioned but its better more than less.The first experience was to reinforce the a particular GRP recipient for water acumulation in the cockpit ground. I had the support of my friend Miguel Casimiro who contributed with his GRP experience

May 3 to 7 - Preparing the topside for painting
This was the last week of paternety license and the last hope of finishing the boat before the summer ! Monday I invited the guy who will spray the boat for a conversation about the detail as also pint preparation evalution. The veridict was that the topside was no proper sanded and I shall used another process i.e an intrface between the Orbital and the sand paper. Also he recommend me to use a way of detecting the flat areas to smoth: randomly soft spray all the topside with a cheap spray and sand it. Its true, the places where the hull had depression or flat spots rised clearly ! so then with the orbital I managed to achieved a smoth and homogenious hull curve, like a baby skin !!!!

April 27 to 30 - Preparing the topsides for painting
Publicar mensagem
Another parental license of 10 working days so it is time again to go ahead with the h19 boat project, yuppi !!!! I decided to paint the deck and topside with 2 component paint so the old paint has to be removed. Another sanding punishement...First I used grip 40 and than grip 100. It would be better to sand with grip 80 in the between to remove the grip 40 marks, nevertheless with some efford the final aspect was fair enough.
My neighbour - Mr. António Assis
In the other side of the wall of the Algés Club (where my H19 is located) is the APL Yard (Porto de Lisboa) where among many other marine labours, Senhor António Assis (in the photo) handles his own workshop just 3 meters away from my boat. Besides the good company I profit a lot with his technical knowlegement about boats.

April 5 to 9 - Sanding the Hull (cont.)
This is the second week of Paternity license, the new rotins with Clara had been setled so i got some few hours for the another lady, so called H19 ! I continued removing old anti-fuling also in the place covered by the trailer arms. I tend to decide to use two-component deck paint, so its required to remove all the paint from the top side. Next week I will be working again after a DELIGHTFUL 4 week out of it.....

March 25 - MY DAUGTHER CLARA WAS BORN
At this thursday I wake up very early to work on the boat, but just for 2 hours because my wife had a doctor appointment at the hospital to follow the praignancy.
Nevertheless, instead of the doctor appointment my beautiful daughter Clara decided to be born !!!
I will stop working in the boat for some time, due to the demanding baby care life...

March 23 and 24 - Removing old Antifulling from the hull - stripping and sanding
Since the underwater hull seems to have a lot of paint layers and I suspected that stripping most of the paint layer would take me a long time, I decided to try a hempel stripping chymical. It works well but timing is the key word. In the first experience I took too long time between product aplication and stripping so paint was to dry to be removed. Finally I tunned the timing to more or less one square meter per aplication.
March 19 and 22 - Preparing the hull for painting
The existent paint in the hull its in a good shape so I decided to just sand it without stripping. I used grit 120 but maybe I will san it again with 240.

March 18 and 19 - Preparing the Deck for painting - Manual Sanding
Now its time to sand that places where the orbital sander don't reach... and find weak places to be fixed by new fiber and resin layers. In the example below I show holes in places where the pulpit are supposed to be attached. Can you imagine what would happen if didn't identify it by striping all the old paint ?
Is interesting that the same grid mean different as it is used manually or by a tool. With the tool I used grit 80 to reach a nice look. With manual sanding, 120 is the proper grid for a nice finishing.
In the end of the moorning of March 19, i start to sand the hull, photos in the next post...
March 15 - Preparing the Deck for Painting
I am finally in holidays with spare time to spend with my dear H19 after long time without any possibility to work on her, partially due to the weather...
I continued in the point where I stoped, sanding the deck, with grid 60-80.
I still have one doubt, what is the most proper sand papper, the white one or the red one ?

December Till February: Sanding for Paint preparation
In the last months I had been sanding the cockpit with grade 60/80 with the orbital sander, as first step of the painting preparation. My litle beautifull daughter Júlia and the wheater (strong winds and rain) didn't let me much time for the boat.
Today is March 6 and theres a lot to do till the project is finished. More than one year has past since the start, much more time than I iniatialy estimated. The follow steps will be :
1) Sand the rest of deck for paint preparation with 80 and then all the deck again with 120
2) Strip the old antifuling fro the hull
3) Sand Hull for new anti-fuling preparation
4) Fiber and resin works:
(4.1) Reinforce desk/hull joint
(4.2) fiber the bulkheads to the hull
(4.3) Cover with resin all the holes in the fiber
(4.4) build another hatch in GRP.
(4.5) Build the rudder Head with fiber and resign
5) Reifit the seats wood structure and test it in place, but not assembling
6) Build up the cabin ground with plywood, apply epoxy cover and test it up in place, but not assembling
7) Paint the bottom of the cabin with dinbolin
8) Fix the cabin ground with GRP to the hull
9) Paint the cabin with dinbolin
10) Fix the seat structure
11) Paint the primary in Deck and hull
12) Paint the Deck with mono-component in red, using roller and/or brush, or ask a cotation for professional deck and hull spraying.
13) Paint the water line with mono-componente in white, using roller and/or brush, or ask a cotation for professional deck and hull spraying.
14) Paint the Hull in Dark Blue with mono-componente Anti-fuling with copper technology15) Assemble deck gear, as winches.
16) build up a tiller for the rudder and rudder head
September to November: Stripping old paint from the Deck
To strip the old gel coat from the desk was easier than from the cabin but eventhought a very much time consuming task. The process it was the follow: in the flat superficies I used a scraper and a hop air gun, it works quite well. In the rought areas I was forced again to use the grinder.
May to September, 2009: Striping all the old Paint from the Cabin
This was a reallty dirty task, to Strip all the old Paint from the Cabin. It consumed me long and hard time.
It wasn't really 4 months working but just 2 months, just 4 hours per weekend, ie. around 32 hours. In the mean time during the beach holidays, I had the inspiring experience of reading the book VERY WILLING GRIFFIN by David Blagden. This book describes day by day the experiency of crossing the atlantic in a 19 feet Hunter19 boat, in the 1972 Transat race.
The old paint was really in bad shape and look, breaking a lot, so I decided to remove it all.

First I tried with a quimical but didn't work well, then I tried an orbital sander but also didn't work well since the old paint was a very hard gel coat and finally I used a grinder. GRP start to appear !
If you plan todo this kind of task with a grind (or not) I strongly advice you to use a professional plastic mask , It makes the difference.

Feb till May 2009: Disassemble
This was the first step, to disassemble the cockpit. Then I decided to continue and take out all the hardware to easy the paint work. Finally I decided to let the craft all nude in his fiberglass and complectly reset the boat.
I spend 4 months in this activity but only working at saturday or Sunday mondays. I got suprised with the delay, but I prefered to invest in a good
job with pacient than go faster for not satisfatory repairing.

The future confirmed that I did the right choise as I found breaked GRP spots.
