How to Make Your Danish Finish
Instead of buying, you can make your Danish oil. However, if you are a beginner and you don’t want to make mistakes, opt for the Danish oil from stores.
Mainly, in the stores, you will get Danish oils that you can use on your MDF wood surface for a beautiful finish. But, if you prefer more control, you can make your Danish oil.
The process of making your Danish oil is straightforward. Take equal portions of boiled linseed oil, thinner, and varnish, and pour each into a glass jar. Importantly, use the boiled linseed oil and not the regular linseed oil. Although you can use regular linseed oil if you don’t have boiled linseed oil it dries slowly and makes the oil difficult to use, Therefore, avoid using it.
Then, stir the ingredients to make Danish oil. Ensure no air bubbles are trapped inside by stirring slowly.
Importantly, you can adjust the ratios of the ingredients to meet your preference depending on the most dominant component. For instance, if you are making Danish oil for regular use, mix the three ingredients in equal portions. On the other hand, for tougher and long-lasting protection, add more varnish.
Alternatively, you can use different ingredients of polyurethane varnish and boiled linseed oil for better properties. For instance, for better moisture resistance quality, you can use tung oil instead of boiled linseed oil. Usually, tung oil offers more moisture resistance compared to boiled linseed oil. However, be aware that tung oil dries slower than boiled linseed oil.
Alternatively, for better water resistance, you can use aquatic varnish instead of polyurethane varnish. The aquatic varnish is more water resistant.
