Urethane is a substance applied to wood to provide a durable clear top coat that seals the wood. Urethane is known for its resistance to abrasion and is also resistant to the yellowing that sometimes occurs with other top-coat paints.
Using lambswool to apply a urethane coating to wood is one of the most preferred methods of application due to the absorbing properties of the lambswool. Using lambswool provides an even coating of the product on wood surface.

Use a fine-grain sandpaper to remove all traces of paint and varnish from the wood surface. If you are applying urethane to a wood floor, you should rent a floor sander.
Wipe the surface of the wood with a cloth to remove all traces of dust and wood particles. A vacuum should be used to remove dust from large surfaces such as floors.
Place the object in a well-ventilated location. If the location is indoors, open all doors and windows to allow for proper ventilation.
Open the container of urethane and pour it into a paint tray.
Dip the bottom of the lambs wool pad into the urethane. Drag the pad lightly across the edge of the paint tray to remove excess urethane from the pad.
Place the lambs wool pad on the surface of the wood and begin applying the urethane in long, even strokes with the grain of the wood. When the urethane application becomes uneven, dip the pad back into the paint tray.
Continue applying urethane until the entire surface of the wood is covered.
Allow the urethane to dry for 24 hours and apply a second coat if desired.
