Can I Refinish Over Existing Finish?

I have a wooden kitchen table and a wooden windowsill that I would like
to refinish because they have losed most of the shine and I need to put
a coat of finish over their surface to protect them. Their condition
are not bad; therefore, I don't want to remove all the existing finish
and refinish them. I am thinking of putting a coat of the same finish
over the existing finish. Can I do that?

Based on the solvent-test using paint thinner, I believe the finish on
the kitchen table is varnish. Can I simply rub a coat of varnish over
the surface? Do I need to sand the surface first?

Based on the solvent-test using lacquer thinner, I believe the finish
on the windowsill is lacquer. Can I simply rub a coat of lacquer over
the surface? Do I need to sand the surface first? I hope that I don't
need to sand the surface; otherwise, I will need to re-stain the whole
thing.

Thanks in advance for any info.

Jay Chan

Thanks for the encouraging info. Now, I can proceed to refinish the
kitchen table and the windowsill.

Sure. Just clean well first and - if necessary - kill any shine by
sanding.

Generally best but only really necessary if it is shiny or the varnish
is bad.

No. The new coat will slightly dissolve the existing and merge with
it.
____________

In both cases, be sure the surface is free of grit & grime.
