DIY Natural Wood Sealant

Kenneth Coppens

Sealant is beneficial for any type of wood item, especially for outdoor wood and wood furniture indoors that may come in contact with liquids. Wood sealants are readily available at any hardware or home improvement store but they may contain ingredients that are potentially hazardous to health.

A natural wood sealant can go on any wood item.

A sealant can be made with all natural ingredients that not only protect the wood but can also give it a deeper, richer color.


  1. Mix 1 part beeswax to 2 parts tung oil in a saucepan. The amount of each item depends on the project. As a reference, 2 cups of beeswax to 4 cups of tung oil is plenty to stain both sides of a standard door.

  2. Put the saucepan on the stove at medium-low heat. Stir the mixture with a metal spoon until the beeswax melts and the oil appears to have an even consistency.

  3. Remove the pan from the heat once the beeswax melts.


  1. Wrap a clean rag around your index finger and dip it in the tung oil and beeswax mixture. Allow any excess oil to drip back into the pan.

  2. Rub the oil on the wood using the rag. Apply the oil with the grain of the wood, rather than against it. Dip the rag back in the oil each time it begins to feel dry.

  3. Allow the oil to set for 30 minutes then wipe the wood surface with a clean rag to remove any excess oil. Let the oil set for at least 24 hours or until it feels dry and apply a second coat.

  4. Apply a total of three coats of oil to the wood. It's important to allow the oil to dry between each coat.

  5. Tip

    Apply the sealant in a well-ventilated area. Tung oil may have an undesirable odor for the first few days.
