Re: Re-Epoxying
Amine blush is water soluble, and comes off with plain water. I've
used ammonia on occasion, but not every time -- I don't believe it's
necessary. Your water and Scotch-brite will do it. Rinse well.

Don't use vinegar.
It may cause problems if you need to add more epoxy/glass
laminations. If you did not use the exact amount of vinegar, the
remaining would need to be neutralized.
Apparently the amines are water soluble. I have just used water and
a mild dishwashing soap to clean the blush off. I have used vinegar
to clean tools that I used with the epoxy...the vinegar turns the
uncured epoxy into a milky colored gelatinous mess.

Scotch-Brite pad, but my efforts have yet to be exposed to the environment, so this will
be one more item to worry about late at night, absent more pressing anxieties.
I thought amines are "basic". In which case an acidic wash would seem to be

OR if you use non-blushing epoxy, you DON'T have to go thru all that.

'choo' -
When epoxy 'cures' it sometimes has a 'film' called Amine Blush. You
NEED to remove it before applying ANY further coats of epoxy or
finishes.
Use a ScotchBrite pad {or other plastic 'steelwool' product}with some
warm water and a dash of liquid detergent {you can add a few drops of
household Ammonia if you're really paranoid}. Scrub well and rinse
thoroughly.
Typically, you can disregard this IF you schedule multiple applications
{of epoxy} about 8 to 12 hours apart. You also avoid sanding between
coats using this technique.

Some one said something about Scotchbrite(?) and doing something to

please tell me again...
