There are a few different oils that could be suitable for the restoration and beautification of wooden house panelling, depending on the specific needs and preferences of the project. Some options to consider include:
Linseed oil: Linseed oil is a natural oil that is obtained from the seeds of the flax plant (Linum usitatissimum). It is a popular choice for wood finishing because it penetrates deeply into the wood and helps to protect it from moisture and damage. Linseed oil is also food-safe, making it a good choice for kitchen items. However, linseed oil can be slow to dry and may require multiple coats to achieve a desired finish.
Tung oil: Tung oil is a natural oil that is extracted from the seeds of the tung tree (Aleurites fordii). It is a popular choice for wood finishing because it provides a natural, matte finish that enhances the wood's natural beauty. Tung oil is also water-resistant and can help to protect the wood from moisture damage. However, tung oil can be expensive and may require more frequent maintenance than some other finishes.
Danish oil: Danish oil is a type of wood finish that is made from a mixture of oil, varnish, and solvents. It is a penetrating finish that is absorbed into the wood rather than sitting on top of the surface like a film finish. Danish oil is used to protect and enhance the natural beauty of wood and is often used on furniture, cabinetry, and other woodworking projects. Danish oil is relatively easy to apply and can be used on a variety of wood species. Overall, the best oil for the restoration and beautification of wooden house panelling will depend on the specific needs and preferences of the project. It is a good idea to consider factors such as the wood species, the intended use of the panelling, and the desired finish.
