So little to be done now, but waiting for the epoxy to set is a pain. I must learn to be patient.


It's maddening when you get toward the end and you have little sequential tasks that seem to take days.

Does anyone know if I have to let the epoxy cure for any length of time before I varnish or can I varnish it straight away?

Whatever the recommended cure time is on the epoxy. Shouldn't need to wait longer than 24 hours.

Matt, does this mean that there has been a change in thinking on the subject of varnishing? I'm sure I've seen a number of posts on this forum that recommend leaving the epoxy a few weeks before applying paint or varnish and Chuck said in one of his posts that he waits a month. I think the reasons are to be sure that all blush has surfaced so it can be removed before application and also to make sure it's hard enough.

Maybe someone has discovered that we don't need to wait after all?

I asked the question of an epoxy vendor once and they stated there was no need to wait to apply their brand of LPU paint.

Waiting for a "final cure" sounds reasonable too. I guess best thing to do is ask your epoxy and varnish vendor.

But waiting and then doing a final sand wouldn't hurt.

Almost finished.

According to my enquiries, it is ok to go ahead with the varnish, and impatience got the better of me. I took a couple of piccies after ther first coat.

So far I'm pretty happy with the results

That is one really great looking boat and you did a wonderful job of making it and finishing it , it looks like glass. She is a BEAUTY. :D

I give it 30 days before varnishing it , this way I can paddle it , scratch it up , get it dirty and find out how it handles....... Then a light sanding and some varnish and it is as good as new. The one epoxy supplier said it can be used after 72 hours but takes 30 days for the epoxy to reach the final curing stage....... If there is a blush to it , so be it , the sanding removes the scratches and all the rest. Then the varnish as the final protective coat for the boat. Any scratches after that , a light coat of varnish and it is back like new.

Chuck.

We want a detailed report on her performance on the water with lots of pictures, please.

I can't wait to build mine, hope I can do 1/2 as good as you did. That is one beautiful boat.

I followed up with another vendor, System Three, and they said at the bare minimum, the epoxy has to be cured enough to be sanded with creating any gooey little balls. So if you sand it and it makes dust, you should be ok.

Waiting longer (up to 5-7 days) can be beneficial to ensure that cure stage but be aware of amine blush issues.
