topcoat for tung oil finish

Francois Quidoz · Jun 9, 2020, 21:30

Currently finishing a walnut tabletop (for a desk) with Tung Oil

it’s in the process of drying / curing, I would like to add a top coat for extra protection

I was looking at the following products, and need some advice:


Secondo (I saw this recommendation on this forum)

or maybe a Wax?

I’m looking for a matt finish with a hand rub look. I want to avoid a "plastic" feel.

Thank you

Thanks for contacting Ardec!

Try 2 coats of Secondo, lightly sanding with a 800 grit paper in between applications.

This should give you the finish you are looking for!

Hello Marilyn, thank you for the response.
I have purchased the Secondo product, looking at the ingredients I see it’s a mixture of oil & drying agent.

do i need to wait the full curing period (15-30 days) of the tung oil before applying?
Or can I apply on top of non-cured tung oil?

Hi François,

You only need to wait at least 3 - 4 days before applying the Secondo.

Kind Regards!
