    Re: Getting rid of amine blush

    OK, I'm outta here! I won't be posting in the woodenboat forum anymore.

    For future lurkers who might be interested in the answer to my question.

    West 207 hardener is also rated as not having blush.

    Thanks Larks.

    I do intend to use PeelPly when applying the cloth but only after my tests on scrap plywood come out 100% good. If that works out, it will reduce epoxy use minimizing weight while...

    Agree. Testing on scrap plywood is exactly what I'm doing prior to glassing my boat.

    Yes, in the "Epoxy Basics" book by Russel Brown that I just purchased, he mentions that 207 hardener does not have amine blush issues. West Systems also mentions the same thing in their 207 ads. I...

    Thank you for your perspectives.
    I think sanding the pre-coat will make the cloth easier to slide around than on bare plywood. But that's just a side benefit. Main reasons for me to pre-coat are...

    Re: Getting rid of amine blush

    Other than the extra work, I think the pros out weigh the cons for pre-coating for a novice like me. Guess for pros, it's needless extra work.

    By the way, Russel Brown in his youtube video said...

    Re: Getting rid of amine blush

    I'll wait 7 days after pre-coating. Then remove the amine blush using the scubber and water. Next day when dry, I'll dry sand to remove the hairs and get a keyed surface. Thanks.

    Re: Getting rid of amine blush

    Extra work is totally not a concern for me. If I "wet" sand the pre-coat the next day and then apply the cloth the following day, is that still considered "green"?

    Re: Getting rid of amine blush

    I'm thinking that "wet" sanding will eliminate the need to wait a week for full cure to avoid green epoxy dust in the air. I will of course be wearing nitrile gloves while wet sanding.
