Outdoor Defense Oil

Real Milk Paint Company

Product Description

Real Milk Paint Company Outdoor Defense Oil provides a Non-Toxic way to finish your outdoor products.  It is made from Pure Tung Oil, pine oil, and zinc.  The pure tung, when absorbed into the wood, provides a deep moisture resistant barrier.  The pine oil acts as a solvent to help the tung oil penetrate deeply into the wood pores – it evaporates in 2 to 4 hours, leaving the tung oil behind.  The zinc, which is a common ingredient in sunscreen, acts as a UV inhibitor and helps prevent the growth of mold and mildew.

Outdoor Defense Oil creates a beautiful matte finish on wood.  It is safe to use on raised garden beds and tough enough to use on projects such as decks, pergolas, and outdoor furniture.


    • Sample:        1 coat 1 sq ft
    • 16 oz:            1 coat 50 sq ft

    • Gallon:          1 coat 400 sq ft


  1.  Make sure your surface is clean and free of dirt and debris.
  2. Shake Outdoor Defense Oil well before using.
  3.  Use in the shade in a well-ventilated area.  If you apply Outdoor Defense Oil in direct sun, the oil polymerizes very quickly and will form a frosty surface on your wood, rather than sinking into the pores.  The pine solvent evaporates in the first 2-4 hours after application and you should be in a well ventilated area until this process is completed.
  4. Apply coats with a rag, brush, or roller.  The first coat should be applied generously – if you are coating any end grain, make sure you apply the oil liberally.  The end grain will be much more porous than the face.
  5. Let the oil absorb for about 40 minutes, apply another coat and repeat.
  6. 2-4 coats will provide moderate protection.  Apply more if the wood will absorb it, up to 6 coats.  You will be able to tell when the wood is saturated because the oil will lay on the surface instead of sinking in.  Make sure to wipe away any excess oil.
  7. Hang your rags outside, spread out, to dry thoroughly before disposing of them.

Note:  Outdoor Defense Oil is not suitable to use over another product that would inhibit its absorption.  The surface must be porous.

You can test if a surface is porous by dropping some water on it.  If the water is absorbed, the surface is porous and will absorb the oil.  If the water beads up on the surface, then you will have to either strip the old finish, or sand it.

If you sand, don’t use a grit above 220.  Finer grit sandpaper will close the wood pores and inhibit absorption.


In high traffic areas, or when your surface looks like it needs freshening, follow these steps:

  1.  Clean the surface with a mild soap and water to remove any dirt, dust, or debris.
  2.   Once the surface has thoroughly dried, test to see if the Outdoor Defense Oil, straight from the bottle, is readily absorbed into the wood.  If it is lying on the top and pooling, then either your surface is not ready to be refreshed yet, or, if the surface is  a very dense wood (such as Ipe or Teak) try thinning the Outdoor Defense Oil.  We recommend 2 parts Outdoor Defense Oil to 1 part Citrus Solvent.Adding the Citrus Solvent will make the oil absorb more readily into the dense pores of the wood.  Since Citrus Solvent is food contact safe, it will maintain the non-toxic properties of the Outdoor Defense Oil.
  3.   Avoid over-applying Outdoor Defense Oil.  If it is pooling on the surface, wipe away the excess with a soft cloth.  Over application, or pooling, may cause a film buildup on your surface that will need to be scrubbed away.
