Examples of Environmentally Safe Varnish or Natural Finishes
Here are some great examples of all natural and oil based environmentally safe varnishes:
Beeswax- The use of this material dates back from ancient times when Egyptians used it as a protective finishing for tombs. The ancient Greeks made use of beeswax in their dolls. Beeswax is an all natural material found in honeycombs,which is secreted out of worker bees' glands while constructing the honeycombs. As your choice of wood coating or finish, it will protect your wood material against moisture and stains. Application however, requires another form of natural liquid oil to soften the beeswax material. You may also find it necessary to re-apply since beeswax wears off in time.
Tung Oil- The most expensive kinds of Tung Oil are those that were naturally derived from cold-pressed seeds or nuts of the Tung tree. Tung trees grow in abundance in far-off mountainous regions of China. A high grade quality of Tung Oil has finer color and dries up fast. In addition, they are said to have elasticity in the sense that the oil applied will seep into wood areas that have flexed or expanded. The lower quality Tung Oils on the other hand, are those that were derived from South American Tung trees.
In using Tung oil, you have to combine it with a citrus solvent or thinner . The high grade quality will have a yellow color while the low grade kind will come as dark green. It produces a natural varnish-like finish and is said to settle well into the surface. The downside to this is that, it is rather expensive.
Linseed Oil- is derived from flax seeds but should not be mistaken as having the same use as flaxseed oil. As wood finish, the raw linseed oil form is used by rubbing it onto the wooden surface. Linseed oil has to be applied in several coats and takes a lot of drying time in-between. Flaxseed oil, on the other hand, should not be considered as a substitute since it is intended as a dietary supplement.
These natural and environmentally safe varnishes and finishes contain natural oil ingredients; hence, they tend to br more expensive than the Low VOC or Zero VOC varnishes, but as VOC free oil-based coatings, you are protecting and improving not only your home but the environment as well.
