Product Description

INSTANTLY ADD DEPTH TO YOUR GRAIN FOR AN AGED-ANTIQUE FINISH

This the same Dark Raw Tung Oil but we have mixed the Citrus Solvent in for you! The darkened color of Dark Half comes from mixing in a naturally occurring resinous hydrocarbon for color. The resin is non-carcinogenic and does not contain any PCB’s.  Dark Half by The Real Milk Paint Company is water and alkali resistant. It resists marring, penetrates well, elastic and unlikely to check. Dark Half penetrates deep into the wood pores filling them up, consolidates the wood surface and builds a dark matte wood finish. It should be kept in an airtight container with minimum airspace.

The Citrus Solvent used in this product is food contact safe and is derived from the skin of lemons, oranges, lime, and grapefruit. The Citrus Solvent evaporates into the air. Any time you crush and smell a plant you smell the evaporative oils, this is why there is a citrus scent to this product.

History

Pure Tung Oil is a finishing product that provides a tough, flexible and highly water-resistant coating for a great wood finish when staining wood. It is classed as a drying oil along with linseed, poppy seed, safflower seed, walnut, soybean, oiticica, and a few other oils. Although it is relatively new to the Western world, tung oil has been known for centuries to the Chinese, and until this century, China was the main source for the oil. It comes from the seed of the tung trees, Aleurites fordii and Aleurites montana, deciduous trees that are very susceptible to frost damage. This vulnerability has restricted the cultivation of the tung trees to China and South America. Tung oil received a widespread application in China: in the building trades as a treatment for both stone and wooden structures; in marine trades as a preservative and water repellant on wooden boats.

It is said to have been introduced to the West by Marco Polo. From the 13th to the 19th century, tung oil had only limited use in the West. In the 19th century, it was adopted by the paint companies to become a major component in paints and varnishes. More recently, tung oil has gained favor over linseed oil for furniture finishing because it is faster drying and does not darken as much with age.

Directions

There are four phases when it comes to using Dark Half for your projects.

  1. Preparation
  2. Application
  3. Curing
  4. Maintenance

Preparation

  • Be sure the surface of your project is free of dust, debris, or grime.
  • Check to see if the surface is porous. (Dark Half works by absorbing into the material and filling the open pores. Therefore, if your material is not porous, it will not accept Half & Half. To test if your surface is porous or not, place a small amount of water on the surface. If the water absorbs, it is porous. If it does not and beads on the surface, you may need to sand and/or strip the surface.)
  • If you need to sand your surface, we recommend not going above 220 grit sandpaper. Too high of a sandpaper grit will “polish” the surface, hindering proper absorption of Dark Half.
  • If stripping your surface is needed, we recommend using Soy Gel: Paint and Urethane Stripper.
  • If you are looking for a lighter color finish, take a look at our Half & Half.
  • We recommend using water or alcohol-based stains on the wood before the Dark Half is applied. Most oil-based stains should be avoided as they tend to seal the wood and prevent absorption of the Half & Half.
  • DO NOT use a wood conditioner. This will seal the wood and prevent the tung oil from absorbing.
  • NOTE: Only very old, dry wood or concrete tend to use unthinned Dark Tung Oil.
  • Extremely dense woods such as teak, ipe, etc may require thinning Dark Half with more solvent (up to 2 parts solvent to 1 part tung oil. Dark Half is already at a 1 to 1 ratio of solvent to tung oil) You can use Citrus Solvent as a natural, food contact safe thinner!

Application

When applying thinned Dark Half, here’s a handy thing to remember: Apply, Absorb, Repeat or Remove

    Apply – Apply the Dark Half to the surface.
    Absorb – Let the oil absorb into the material.
    Repeat – Do what you just did, apply the oil and let it absorb.
    Remove – When the oil isn’t absorbing and pooling on the surface, remove it with a rag.
    Cure – Let the tung oil go through its natural curing process.

For the best results, you want to saturate the material with the tung oil to the point where a majority of the surface is no longer absorbing the oil. This will look like puddles on the surface even after waiting 40 minutes. Just like a sponge, the wood (or other porous surfaces) will only absorb so much oil before it can’t anymore. This saturation is achieved by doing multiple coats.

You can apply Dark Half with a brush, rag, roller, or even a pump sprayer depending on your project and needs. We recommend brushes and/or foam rollers for most projects.

  1. Apply a generous first coat.
  2. Let the tung oil absorb into the surface, waiting if needed, up to 40 minutes.
  3. Apply another coat, let it absorb, and repeat the previous steps.
  4. Continue this process until you reach the desired amount of coats or have fully saturated the wood. You can tell the wood is saturated when the oil puddles on the surface and no longer absorbs oil across a majority of the surface. To be sure, wait 40 minutes. If the oil is still puddling, then you will know the surface is saturated.
  5. Taking a clean rag or cloth, remove any excess tung oil that is puddling or pooling on the surface.
  6. Hang those oil-soaked rags outdoors to dry. DO NOT pile the rags or put them in a container.

For the best finish, we recommend letting this application rest and settle overnight. The following day, apply one or two more coats of Dark Half to the surface of your project, following the same steps outlined above.

Curing

Dark Half does not contain any additives to speed the drying process, such as heavy metallic dryers. Because of this, it can take up to 30 days to completely/thoroughly cure by its natural polymerization process. Provided below are some guidelines to follow during the curing phase.

  • Dark Half cures best in warm, well-ventilated places. The warmer and more ventilated the area, the faster it will cure.
  • Placing objects on the surface will “suffocate” and prevent the tung oil from curing properly. If there is no airflow between the surface and the object, it should be removed until the curing is complete (30 days).
  • During the first 7-15 days of curing, you can use the surface. However, you will want to avoid getting it dirty or allowing liquids to puddle on the surface.
  • As the Tung Oil cures, its durability and resistance to liquids and dirt will also increase. The first 7-15 days is when the oil is at its freshest and weakest state. After that point, increased regular use of the surface can take place.
  • As the Dark Half cures, it slightly expands and may push fresh oil back to the surface. Check for oil that may be seeping to the surface and remove it, if found, with a rag.

For butcher block, wood countertops, and etc.

  • Avoid getting dirt, water or other liquids on the surface of the butcher block for at least the first 7-10 days.
  • We recommend putting wax paper down near sinks when doing dishes and other activities that splash water about. This will prevent the water from pooling on the surface and can be easily removed after the dishwashing.
  • Avoid putting cutting boards, appliances, dishes, and other objects that sit close to the recently refinished surface for extended periods of time. These objects prevent airflow and can hinder the tung oil from curing.

For indoor floors

  • Feel free to move about on your floors with either socks or rags underfoot after applying the Dark Half. Moving across the floor with rags or cloth material is actually recommended as it will help buff and prevent any oil that may seep to the surface.
  • You can move furniture back into the room after applying the Dark Half. However, keep area rugs and furniture that sits close to the floor off until the full 30 days are complete. We recommend placing plastic sliders between the floor and wooden legs of furniture. This will prevent the furniture leg from naturally pulling the oil out of the floor.
  • While the oil is at its freshest (usually the first 7-15 days) do not walk across the floor with dirty shoes. The dirt will be pressed into the fresh oil and will be hard to remove.
  • The floors can be temporarily covered with plastic, painters cloths, or cardboard for no more than a day.
  • Avoid having any liquids sit on the surface.

For outdoor decks, siding, and other wooden surfaces

  • Freezing temperatures can affect the curing of tung oil. You will want to delay your project until the temperatures will be above freezing for a minimum of two weeks during the curing of the tung oil.
  • Do not apply the Dark Half in the direct sunlight. The heat from the sun will flash polymerize the tung oil while it is on the surface.
  • Try to apply Dark Half when rain is not in the forecast for a week or two. None of us can control the weather and should it rain on your newly oiled deck don’t worry. As soon as possible, remove the water from the surface using a leaf blower or a broom. You just want to prevent the water from staying on the newly finished surface.

Maintenance

The beautiful thing about a Dark Half finish is that the maintenance of it is easy. We recommend cleaning the floor with mild soap and hot water. Avoid using harsh chemicals, acids, or strong solvents to clean the surface.

Maintenance coats are on an as-need basis. Outdoor projects may require more maintenance than indoor. Heavily used areas can be expected to require more maintenance than lightly used areas. Typically, surfaces that need maintenance have a very dry, or lackluster appearance compared to when the finish was originally applied.

When doing a maintenance coat you do not need to sand the surface again. Here is what we recommend;

  1. Make sure the surface is clean and free of dust or debris.
  2. Make a 2 to 1 ratio of solvent to Tung Oil (2 parts solvent, 1 part tung oil). This thinned mixture can easily find any open pores and fill them.
  3. Thinly apply this mixture using a clean cloth. Simply wipe it onto the surface, no need to lather it on.
  4. Wipe up any excess that may be on the surface with a clean, lint-free rag or cloth.
  5. Allow this thin coat to cure for 24 hours.
  6. Hang oil-soaked rags outdoors to dry.
  7. Go back to enjoying the surface like normal!

Hints & Tips

  • Do not apply or leave fresh tung oil on the surface in direct sunlight. This will flash cure it on the surface and will turn white.
  • Do not sand between coats of tung oil. This is an application technique for tung oil varnishes, not pure tung oil.
  • Do not use Dark Half over oil-based sealers, stains, and finishes.
  • We recommend using a water-based stain to change the color of the wood before tung oil is applied (if a color other than that provided by pure tung oil is desired.) For a lighter, all natural, tung oil finish check out our Pure Tung Oil and Half & Half products.
  • Do not use the “Green” thinners now being sold. They contain water and will not mix with the oil.
  • Remember, adding petroleum mineral spirits or other thinners, the oil may become toxic with these substances mixed into it, although the finish produced is not toxic because the thinners evaporate.
  • The number of coats of oil to be applied will be determined by the intended use of the piece. One to two coats is enough for decorative work, paneling and molding. For surfaces that receive moderate to heavy use need a minimum of three on up to six coats for maximum protection.
  • Apply till the surface reaches the saturation point. This will be evident as the surface will not absorb more oil.
  • Renewal and/or maintenance coats are thinly applied with lint-free cloths (old bed sheets work well) or old t-shirt material on an as need be basis. A two parts solvent to one part tung oil mixture is recommended for maintenance coats.
  • Do not get hung up on the number of coats, let the wood tell you when it has reached its maximum saturation.
  • Dark Tung Oil will be in the wood up to the surface not on the wood like varnish or Polyurethane top coat. The end result is more like seasoning a cast iron pan. This product will give you a surface that will stand up to vigorous use and spills: water will bead on the surface.
  • After the tung oil as completely cured (30 days) cleaning of the surface can be done using hot water and mild soap, such as dish soap. Avoid using hard chemicals or acids for cleaning.

What its made of

We believe in being honest with what is in our products. So, that’s why we provide the ingredients used in them so you can rest assured knowing exactly what’s in the product you purchase from us. It’s just a way we make it easier on you.

Dark Half is made of

  • Pure Tung Oil
  • Resinous Hydrocarbon
  • Citrus Solvent

What is…?

  • The resinous hydrocarbon used to darken and color the pure tung oil is naturally occurring, non-carcinogenic, and PCB free.
  • Pine Oil is a naturally occurring terpene hydrocarbon. Terpenes are naturally occurring 10-carbon organic molecules manufactured in nature by green plants. They are raw materials for many of the flavors and fragrances enjoyed by man. Most terpenes are designated by GRAS (Generally Recognized As Safe) by the FDA and FEMA (Flavor Extracts Manufacturing Association) and are approved for human consumption. The pine tree is the worlds largest commercial source of terpenes, the volatile oil from the tree, the largest volume essential oil found in nature.
