How to Glaze a Wall With Varnish
If you have an old paneled wall made with real wood (as opposed to a
modern veneer), and the wall has become dull and dingy, there's no
reason you can't varnish the wall the way that you would a piece of
furniture. Varnish is a better material to use in these instances than
polyurethane, because it looks more natural and is less shiny. By
thinning the first coat of varnish, you will help make the subsequent
coats stick better.

1
Go over the wall with your sander and medium-grit sandpaper, with the grain of the wood, taking off any surface material and getting it flat and dull. Don't sand down into the wood of the wall itself, just the surface. Wipe it down with tack cloths to take up any residual dust.
-
2
Mix varnish and paint thinner in a bucket, in a one-to-two ratio of thinner to varnish. Will thin the varnish for the initial coat.

3
Brush the thinned varnish onto the wall, starting in the top furthest corner and working your way down. Keep it in a very thin, even coat, avoiding any drips. Do the whole wall.
-
4
Let the varnish dry for eight hours.
-
5
Apply a second coat of varnish, full-strength, again in a thin, even layer. Let it dry for eight hours.
-
6
Lightly sand the wall with your sander and extra-fine sandpaper, which will just be enough to dull the varnish surface. Wipe off the dust with tack cloths.
-
7
Apply a third coat of varnish (full strength) in the same manner as the second. Let it dry. If a fourth coat is needed, de-gloss the surface first as before.
