A First For Me... Amine Blush

Working on bits and pieces, I began coating the cheeks for the rudder stock and the anchor well deck with epoxy.

The anchor well deck received two coats without any issues but the third coat had an oily/waxy film after the epoxy cured. So did the first coat on the rudder stock cheeks. I was surprised. This is the first time I've experienced this amine blush phenomenon in the eight years I've been using epoxy. Yeah, I know, "...even when you can't see it, it is there..." but, honestly, I've never experienced it before. I've never washed epoxy coatings with warm water before applying the next coat and I've never had a failure...

From what I've read, the likely culprit was this week's hot and humid conditions (although I have used the same resin and hardener in similar conditions without issue). I'll need to mind conditions a bit more closely than in the past. Still no success in finding a trailer...


  1. Glad to see you back at it Bob!
    I have been looking at a trailer for the pf:
    it actually hinges so that the boat can slide onto it and then just closes to straighten the trailer out and lift the other half of boat out of the water; great for beach work.

    1. Thanks for the trailer info, Rik. That hinge feature will be nice for beach launching. With many improved ramps around here there isn't much need for launching off the beach - although there are a few places I can think of...


  2. We are stuck with all this beach as the only means of getting a boat in the water... What a drag. NOT!

  3. Sounds like you've been very lucky with your epoxy work so far! If you'd like to find out a little bit more about amine blush, why it occurs and how to prevent it, you may find this article of interest:
