What are some tips for varnishing wood?

Varnish should be applied in the direction of the wood grain. Due to the transparency of varnish, regular inspection of the wood under strong light may be necessary to avoiding missing spots. Varnishing one section at a time ensures more consistent results.

After the initial application of varnish, brushing it out helps create an even coat. Varnish tends to lift the grain of the wood, and sanding down the first coat of varnish can help prevent this. The wood may need multiple coats of varnish. Prior to adding another coat, use a damp cloth to dust the varnished area and let it dry completely.
