ClearCoat over 23k Goldleaf

Post by Kevin W Betz » Sun Apr 20, 2014 10:28 pm

I am doing a wood transom tomorrow.
It will be 23K, non-burnished, with a
Red Outline & Black Shade.
The customer will Varnish over the Job.

1- Would you Size, Gild and Clear the Gold ?
2- Size, Gild, Outline Red & finish the Black
Shade, with no Clearcoat ?

My thought is after he applies the Varnish over the Gold &
Paint, the Varnish should not affect anything.

(sorry to be late, you will have the job done by the time this is posted..)

My feeling on gold leaf is that you try to NOT overvarnish it - the color is dulled and the longevity is compromised.
But if it will be rubbed (as on a vehicle or boat) then I like to spin the gold first. My imagining is that the velvet makes a series of tiny circular dents in the gold, like a vinyl record but much smaller, and when the clearcoat goes over it the little valleys act as lenses. In any case, spinning makes up for some of the lost brilliance.

On boats I would do as you suggest in (1): size, gild, (spin,) overvarnish and let dry. Then when you come back the gold is protected and if you make a mistake your paint can be wiped off without affecting the gold. That is of course the coward's way.
If you go with no varnish, as in (2), then one needs to check what kind of clearcoat is being applied - the size under the gold does not cure as fast as the other paints. But it does mean that all the clears are the same, which should be a good thing.

Hi Lee.

Thank You for your response. After talking with the customer, I opted
to size, leaf, burnish without Engine Turning and Shade 1st Day.
I then Cleared with Sikkens and Outlined the Red on the 2nd Day.
They did not want the Spin in the Gold, they wanted the Matte finish look.
I cleared the Gold because he said that would help him when he applies
the Varnish. Since it is a New customer, I felt by clearing the Gold, no
harm.

Nice job. And with the shade dry you can clean up the edges with the red on 2nd day.
Good to see the boat is indoors.

When you were wiping off the extra gold did you do the final wipe in a horizontal direction? It's not really spinning, but even a light wipe with velvet or cotton will leave some micro-scratches, and most inscriptions read better if they have a horizontal 'grain'.

Yes Lee, I lightly wiped left to right.
What kind of Clear do you use, if needed ?

If the boat owner is going to be applying more coats, i will try to use what they use so it will all be compatible.
If I am the last coat I'll go with a good marine varnish with UV protection - a 'spar' varnish or 'n's' varnish.
The automotive clears may be even better but I don't know enough about them.

Nice work!

Just a curiosity:
Was the transom already coated in some kind of varnish or did you work directly on the "naked" wood?

Two reasons for asking:
1) I keep thinking it'd look pretty cool to do a job like this on top of a few millimeters of transparent surface, so as to seem floating just above the "surface" (I cant get enough of those optical illusion effects) or if working on varnish is counterindicated in these cases?

2) i remember my dads buddies all had wood boats with about ten or fifteen layers of varnish and they sanded the varnish down at least three or four layers after every season and redid them, i dont know if they were just overly protective, if there were environmental abrasion issues (these boats sailed both the Baltic and the Atlantic) demanding it or if it's "just how its done". Im thinking if your job is close to the surface or if it's safely tucked under...

As i said, just curious, i've been thinking of offering services to boat-people when i've honed my skills further :)

Hi Lorenzo.

The Customer had applied a couple coats of Varnish, not sure how many,
then sanded it to remove the Sheen. This helps the Size to adhere as well
as the next coat of Varnish. I am sure the more coats of Varnish over the Lettering
would achieve the look you describe.
