Introduction
In this article, we will explore the process of applying linseed oil to wood and determine its durability and waterproofing capabilities. Linseed oil is a popular choice for wood finishes due to its ability to enhance the natural beauty of the wood while providing a protective layer. We will go through the step-by-step process of applying linseed oil and discuss the results of durability testing.
Preparing the Wood
Before applying linseed oil, it is crucial to prepare the wood surface properly. Start by sanding the wood to ensure a smooth and even finish. Once the sanding is complete, use a damp paper towel to wipe away any residue and ensure a clean surface. Follow up with a dry paper towel to double-check for any remaining residue.
Applying Linseed Oil
To apply linseed oil, it is recommended to wear rubber gloves for protection. Begin by applying the linseed oil directly to the center of the wood board and gradually work it outward. Pay special attention to knots and areas with heavy grain as they tend to absorb more oil. This initial coat should be allowed to sit for approximately four to five minutes.
After the initial sitting period, examine the board to see areas of penetration and those that may still have oil sitting on top. Take a rag and redistribute the oil, focusing on areas that have absorbed the most. Knots and heavy grain areas usually require extra attention. Move the oil around to achieve an even distribution.
Removing Excess Oil
Once the linseed oil has been applied, it is essential to remove any excess oil to prevent a sticky finish. After allowing the board to sit for about 30 to 45 minutes, run your fingers along the edges to check for any excess oil that may have seeped underneath. If excess oil is present, use a paper towel or a different cloth to remove it.
Next, use a dry cloth to distribute any remaining oil evenly across the surface of the wood. If you have nurtured the board properly during the waiting period, there should not be much excess oil to remove. If necessary, use a paper towel to remove excess oil initially, but come back with a cloth to buff the surface. Apply a little elbow grease to bring out the shine and make the grain pop. This buffing process gives the wood a polished and finished appearance.
Allow the board to sit for another hour and double-check for any areas that may have dried out. If necessary, repeat the oil application process until the wood no longer absorbs any more oil.
Durability Testing
To test the durability of the linseed oil finish, a series of common household items were applied to the board. The board was divided into two sections: one side with wax and one side without. The items were left on the board for over 24 hours to assess the damage.
Water rings were the first items tested, as they represent a worst-case scenario for potential damage. Despite the added durability provided by the wax, the linseed oil finish was unable to prevent water rings from forming. However, it is worth noting that in another video, the removal of these water rings may be explored.
Additionally, green paint and pencil marks were applied to the board. While the linseed oil finish offered some protection, there were still remnants of the green hue left behind. The use of a damp cloth was not sufficient to remove these marks. A dry eraser was slightly more effective but still did not completely eliminate the paint and pencil marks.
In conclusion, linseed oil is not the preferred choice for a tabletop finish due to its limited durability in the face of common household items. While the wax did provide some added protection, there was still significant penetration from the tested products. Alternative finishes may offer more robust protection for similar costs.
