Is it raining to much?

[bronco302]

Ok I have been moving along on the Southwind. All my seams are hard as a rock and the clear as well as glue mixes on my bulkheads have been fine. Last three days I have been working on fillets and it's been raining for all week. The clear I have primed the seams with for my fillets is peeling up from some bare wood and even my butt seams that were done a couple of months ago. These were sanded, feathered,cleaned and degreased. Is there to much moisture in the air to be laying down epoxy? The only other thing I'm doing and I've always done it is wiping the seams with Lacquer thinner. I give it about ten minutes to flash off before I paint on the clear epoxy. Then I wait 24 hours do a fillet and prime another seam. I'm using Marinepoxy and medium hardener from Boat Builders Central. All my measures are the same and mixing procedures are the same.

Big question, if the edges of the clear is peeling do I need to remove the three fillets I have down? I'm going to be very surprised if the answer is no they should be ok. Thanks guys.

If it's Minwax varnish...well..... let's just say what I'd tell you would likely make you cry.

If it's marine varnish, the only seam prep you should need is light sanding and maybe a quick wipe with acetone if you suspect amine blush.

The lacquer thinner you're using MIGHT be attacking the epoxy. But not likely.

I'm not 100% sure i understand this statement:

The clear I have primed the seams with for my fillets is peeling up from some bare wood and even my butt seams that were done a couple of months ago.

You mean the varnish you're putting on? Is is clear coat paint? Brand? Knowing this info will help me and others lend advice.

I'm not using any varnish, only clear epoxy. I'm getting spotty bonding on some bare wood and cured epoxy at my butt joints that is well sanded, and cleaned. I brush clear resin mix on a seam let it cure 24 hours lightly sand then lay down a fillet of wood flour with some glass bubbles. I'm concerned the epoxy under the fillet may have spots that are not well bonded. The only thing different from even last week is the beginnings of cool weather in East Tennessee and several days of rain. Could all the cool moisture in the air interfere with my epoxy bond. Thanks.

The moisture could be a factor. What do you mean by "clear" epoxy? Epoxy with no filler?

[bronco302]

Yes no filler, like putting a saturation coat on under the fillet. I tried to pop a couple of places in the fillets loose this morning with a sharp chisel before work. The edges would chip where the chisel cut in to the epoxy but everthing seemed tightly in place.

All that said from the weather reports and the feel of the air I may need plan my work to times I can fire up the heat and knock off the chill and damp in the shop instead of trying to grab a quick hour after work.Thanks.

It sounds like moisture was the culprit.
