Filling the weave completed!

Five more hours this week end to complete sanding of the vaka deck/cockpit and subsequent coating with clear epoxy (almost 800 grams). Here's a pic taken yesterday during the sanding session


and here's one taken this morning after the second coat.


You can see the milestone beer on the left because Cinzia protested when I tried to put it on the freshly coated deck.
In the meantime we tested the paint samples prepared before. While it looks that enamel adheres well on cured epoxy, the water based acrylic enamel (latex?) that we tested seems too soft. After three weeks we can easily dent it with a nail, so it's either too soft or cures too soft on epoxy. On the other hand, the two-part polyurethane enamel that we tested before is much harder albeit very unpleasant to apply. We'll soon try a one-part water based polyurethane enamel.

Total work time to date: 651 hours

  1. I've been very satisfied with the two-part polyuretane paint applied on cured epoxy. It's perfecly transparent and works great if you want to leave the wooden pattern visible. On the two sides of the hull I mixed it with a specific colorant, getting a light-blue paint, which it is said it works better as UV filter (compared to the transparent).
