Varnish: Full Curing time before silicon overlay?

[MarkJ]

Hi

I am varnishing part of the galley with varnish (Captains) and need to lay a bead of silicon on the bench and wall join to catch the sink drips.

How much curing time would you leave after the last coat before putting silicon over a bit of it?

Thanks

PS varnishing sux. As soon as you do one small bit the whole rest of the boat looks like it needs a coat too.

What's the temperature / humidity?

In San Diego conditions it says I could have done it in 24 hours but it always felt a lot more realistic in 48-72.

Agreed that varnish is silly. If you need to protect the wood that's one thing, but varnishing for the sake of beauty is a fool's errand.

Every day: 31 deg C / 87 F at 75% humidity daytime, 84% night.

How many coats did you lay? Did you stack them? Problem is taping off for the caulk job ( I refuse to say silicon for personal bias reasons) peeling up the tape can be a real downer to your beautiful varnish.. If you are in no hurry, wait a week, use easy release tape .

I always used light coats and pulled when the varnish is wet. It means taping between jobs which is a pain but less chance of chipping.

5 coats, not tape and I wont tape for the silicon. Just bead and finger. I find any overage of silicon (sorry Ericka) rubs off as its so thin.

A week is what I thought

That means I cant wash the dishes till then!

I love Captains (better than Flagship in my mind) for how is lays down.

I would say a week wait would do. Too much time and nothing happens, too little and sadness..

go ahead and use tape. THis will give you a fine edge.

Silico- I mean caulk, and he doesn't tape off. Must be nice living in the fast lane

I would avoid silicone. Once on the varnish, you will have to remove the varnish if you ever want to recoat. Silicone will create "fisheyes" where the finish won't adhere, and sanding it will drive it into the finish. Use a clear caulk, possible Lexon, that is paintable instead
