Wood Finishes Explained: Stain, Oil, Polyurethane and Paint

How finishes protect wood and change its look, with tips on choosing and caring for them.

What a finish does

A finish seals wood against moisture and wear and sets the color and sheen. Without it, wood absorbs spills and grays in the sun.

The finish you choose shapes how the piece ages.

Stain and toner

Stain adds color and shows grain. It needs a topcoat for protection. Test on a scrap, because the same stain looks different on each species.

Blotchy woods like maple and cherry may need a conditioner.

Oil and wax

Oils soak in and give a natural look and feel. They are easy to repair and need occasional refreshing.

They offer less scratch protection than film finishes.

Polyurethane and varnish

These form a hard film that resists wear, water and heat. Water-based versions dry clear and fast, and oil-based versions add warmth.

Multiple thin coats work best.

Paint

Paint hides the grain and offers any color. A good primer, a smooth surface and a durable topcoat make a lasting finish.

Cabinet-grade paints cure hard.

Caring for finishes

Use mild cleaners, wipe spills and avoid harsh chemicals. Refresh oil finishes and recoat film finishes before wear reaches bare wood.

Our advice in one sentence

Choose the finish for how the piece will be used, and always test on a sample of the same wood.

Questions

Quick answers.

Should I use oil or polyurethane on a table?

Poly protects more, and oil feels more natural and repairs easily. It depends on how you live.

Why does stain look different on my wood?

Species, grain and sanding change how wood absorbs stain.

How often should I refinish?

It depends on use. A well-finished piece can go many years before a refresh.
