How To Waterproof Reclaimed Wood Furniture

Did you build reclaimed wood furniture for your bar or restaurant and plan to use it for the outdoors? The good thing about reclaimed wood is that it is highly durable but you can still take a few steps to get the most out of its durability when weather conditions such as rain present themselves.

Below are the step by step instructions on how to waterproof your reclaimed wood tables, chairs, and more, so your furniture stays in tip top shape.


First you need to decide what oil to use. You can choose from walnut, linseed, and tung. The difference among these is that walnut oil is similar to olive oil, linseed oil is commonly used but is poisonous when boiled, and tung oil is one of the pricey options and most commonly used on small projects.


When you go shopping for your oil, usually the more the better so you can use it several times throughout the reclaimed wood’s life. If you have a large amount of reclaimed wood furniture that needs to be waterproofed, we recommend purchasing an exterior stain and sealant.

You will also need some lint-free rags, and turpentine and apple cider vinegar to create a mixture with the oil.
