How to Thin Linseed Oil

The use of linseed oil to cure wood surfaces has been in practice for hundreds of years. Linseed oil is a natural preservative, and is very effective in curing wood to withstand both the elements as well as the wear and tear that, as in the case of a wood floor, receives. Linseed oil will absorb into the grain, even on a molecular level with wood, preserving it and giving the wood surface high durability. The primary troubles in using linseed oil is that raw linseed oil takes a long time to cure, up to two weeks in a dry, well ventilated area and, ultimately, a couple of months if it is applied to surfaces that are exposes to extreme heat, cold, or high humidity. The bottom line is that pure linseed oil can be very difficult to work with, particularly in a case where it is a wood floor or deck that is being finished with the substance. Here you will find some tips on thinning linseed oil so that it retains it's preserving qualities, while being modified into a substance that is both easily worked with by modifying the material into something that will actually dry in a span of time that makes it realistic to use.

Step 1 - Gather Ingredients

All of the materials that are used are flammable. There are numerous stories of linseed oil spontaneously combusting, so make sure that you are working in a well ventilated area and that you know how to dispose of any stirring utensils or rags that become saturated with any of the above solutions. You may want to put cardboard or several layers of news paper down on the work surface to protect from splashes or spills.You will also

Step 2 - Mix Ingredients

Don the safety goggles, gloves, and coveralls to protect your eyes and skin from any splashes or contact with any of the solvents or materials that are used. Using a glass measuring cup, and one that you will not want to use again, measure out equal parts of the linseed oil, spirits, and varnish into the metal bucket or container. Use a wooden utensil or paint stirring stick to mix the solution together.

Step 3 - Storing the Finish

Any unused portion of the mixture will need to be stored in a heavy duty metal can or container, and should be tightly lidded. Any rags or applicators that have been used should be stored in a metal bucket filled with water until proper disposal can be obtained. Check with you local ordinances on disposal of such items, and the safest, and most environmentally friendly manner. Store all materials and used applicators away from heat and flame, as they will be incredibly flammable.
