: Thanks for the replies guys I'll call the manufacturer tomorrow so far it hasn't produced any amine blush just the orange peel in some areas I've tried to put on only thin coats the weather is typical rainy cool northwest winter but a heated garage , it almost looks like the epoxy pulled away from some areas sortof like a water and oil thing I just wonder if maybe my hands had left a bit of oily residue ? oh well I'llcall tomrrow Thanks for the input:but you can probably get a good chem.-bond even up to 48 hrs.

: Bert,

: You should check the literature for the epoxy that you are using as for time
: between coats. I have seen some epoxies start to get that waxy coating
: "amine blush" within 24 hours under certain conditions. You
: should never epoxy over this. It will not bond and will lift or orange
: peel.

: Do some more checking and hopefully more feedback on the bulletin board.

: I always use thin coats and recoat when you can touch the surface without
: leaving a finger print, but still slightly tacky. Usually in about 6-8
: hours is the time I use. If I can't finish things up in this time, I give
: it at least 48 hours to cure, then use a Scotch Bright pad and do a wet
: sand with it to remove any surface wax. If I need a structural bond over
: this I will then use 60 or 80 grit paper. If it is just filler coats, the
: Scotch Bright treatment is sufficient.

: I always use the wet sand method, as the surface waxes on the epoxy will just
: gunk up any sand paper when used dry. So scrub it clean, then sand it if
: necessary.

: Good luck

: Tom
