Let it dry for some hours, and then rub with a cloth: flannel or a piece of felt is best.

Put on several coats, leaving the work over night between coats.

Rub often with a warm cloth.
(c) _Varnishes._ The function of varnishes is to cover wood with a hard, transparent coating that is non-porous and impervious to moisture.

There is a great range among them, from thin, easily worn, dull finishes to durable, strong, and highly polished coatings called "rubbing varnishes." The polished surface can be secured only by much labor thru the application of successive thin coats of good varnish, carefully rubbed down.
Varnish may be applied to wood, stained, painted, or in its natural condition as well as to metal, leather, paper, and various other substances.

A good varnish should be adhesive, that is, it should cling firmly to the surface to which it is applied; it should be elastic, so as not to crack on account of the expansion and contraction of the material to which it is applied; it should dry in a reasonable time; it should be limpid so as to flow easily in application; it should be transparent and brilliant when polished; and it should be durable.
