FIBERGLASS ACTION,
sanding sanding and some more sanding
16/07/21
Again the date on that post doesn't match with the real date of when the action was done. I'm just so late on my scheduled and very took too much delay on writing and posting regularly this blog diary. My apologies.
My dad came over to help me to apply all the glass fiber stripes on the edges and each plywood connection. The bow got extra reinforcement, as well the transom and the two stripes where the dagger board support are going to mounted later on.
I also spent a whole afternoon doing the best preparation as possible so that on the big day of glassing goes as good as possible. So I pre-cut each fiber stripes, mark them and make sure they will overlap each layer below.
I had to apply 1200g/m2 (laminating 1170 G / m2 require) because the hull is made with Okume 9mm plywood.
1x390g/m2
1x425g/m2
1x390/m2
For a total of 1205 /m2
plus PeelPly all over
I was planning to complete the whole glassing action in one day. applying the three layers one after the other. And luckily fort that I had a wonderful helping team who came. My sister and brother and two ladies friends extremely motivated and effective. Instead of the 8 hours of hard labor I was planning we complete the whole task in less than 5 hours. peel ply included. I don't remember exactly how many litter of epoxy we used but between 10L. and 15L. I know, sorry not very precis but i forgot to write it down. But I think included the epoxy we used the day after to fair the all hull it was close to 20L.
With my brother and sister the day after we apply a thick layer of epoxy fairing material all over the hull. Microballon and some Thixotropic agent (to reduce the dripping. Probably 90% of that will have to be remove to get a smooth and slick hull. That mean a lot of sanding. But very a lot. Very dusty atmosphere at the boatyard.
After a fey day and some liter of sweet needed to sand down the hull it was finally time to apply the first layer of epoxy primer. And this was a very satisfying moment of that building process. So gently and peaceful after the horrible sanding of the last few days.
We apply three coat of primer, in between slightly some sanding to get ride of some minor imperfection. A good tricks is to add some color or pigment into the white primer, so that when you have to do some sanding you know how deep you are sanding. Kind of onion layer technologie. Paint layer color code.
