If you have recently bought some new teak furniture for your patio or backyard (or if you’re thinking about buying teak furniture soon), you may be wondering which product you should use to preserve the look of your beautiful teak furniture. You might be considering treating the furniture with teak oil or teak sealer, but you’re not sure which would be the best way to go. In order to answer this question, first it is important to understand what makes teak wood special. Then you need to know exactly what teak oil and teak sealer are, along with the benefits and limitations of each. After this you’ll be able to make an informed decision on how to care for your new teak patio furniture so that it lasts for a lifetime.
Real teak oil is already inside the wood
Teak is a tropical hardwood that grows in countries such as Indonesia, Myanmar, Thailand, and India. It has been a prized wood for centuries due to its special qualities. Grade A teak is a very dense wood that comes from the heartwood of mature teak trees. Mature teak wood is full of its own natural oil which protects the wood from damage by water, fungus, rot, insects, and changes in temperature. This oil gives new teak furniture a lovely, rich golden color.
Why does teak wood turn gray?
The oil in the very outer layer of teak wood will begin to evaporate and oxidize after being exposed to the air and sunlight for a few weeks. You will notice that the rich honey-like color of new teak will begin to fade and become more a of a pale yellow. Eventually, if left alone, the color of teak furniture kept outdoors will fade away even more to leave a light, silvery gray. Some people like the soft look of weathered gray teak. If you are one of those people, then you don’t need to use any teak oil or sealer on your furniture. Simply give your furniture a good thorough cleaning at least once a year with a teak cleaner, and you’re set. Regular cleaning will help prevent dirt from building up or moss from growing on the exterior of your furniture. It will also help to make sure the teak fades to gray more evenly.
If you’d prefer to try to hold on to the golden color of new teak, then you’ll want to use either teak oil or teak sealer. But one will give you much better long term results. What is the difference between the two?
What is teak oil?
The first thing that you need to understand is that “teak oil” is not teak oil. What do we mean by that? The “teak oil” sold in stores does not contain any oil from the teak tree. Instead, teak oil is actually made from either linseed oil or tung oil with some varnish and thinners mixed in. It is only marketed as “teak oil” because it is supposed to be used on teak.
When it is first applied, teak oil will give your teak furniture a lovely golden glow and shine. It will probably look spectacular for a couple weeks. However, after that the color will begin to fade again. Why is that? It is because the oil evaporates and leaves the wood dry again, sometimes even more dry than before. Teak oil does not help extend the lifetime of your furniture. The natural oil that is already found within the wood is good enough to protect it from pests and the weather.
Teak oil is only a temporary fix to beautify the wood. If you really want to, you can go ahead and use teak oil, but you’ll find that you need to reapply it every few months. You may find this high maintenance routine getting old quickly. Even worse, the solvents in teak oil can cause the natural oils found in teak wood to break down and deplete more rapidly than they would if you did nothing. Another problem with teak oil is that it gives some types of fungus an ideal environment to grow in. Many people complain that black spots appear on oiled teak furniture, and this is the reason why.
Why is teak sealer better?
Teak sealer, on the other hand, gives a layer of UV protection to teak wood furniture. It also contains ingredients to prevent mildew growth. It makes a barrier to prevent the oxidation of the outer layer of wood, so that your teak furniture won’t turn gray. Teak sealer only needs to be reapplied about once a year, so this is one large advantage it has over teak oil. Semco Teak Sealer is a highly recommended water-based sealer to use, and it comes in both clear and tinted varieties.
Before applying teak sealer, you should thoroughly clean your teak furniture. Golden Care Teak Cleaner works really well at cleaning any residue from the wood and brightening it before applying a sealer. After cleaning, allow your furniture to dry completely, then a thin coat of sealer can be applied using a sponge or a hand-held pressure sprayer. After waiting for an hour, you can apply a second thin coat. This will dry in a couple of hours, and you’ll be able to use your teak furniture the next day. You don’t want to use teak sealer on brand spanking new teak furniture. Instead, let it weather for at least two weeks. Some sealers contain a tint which will return your furniture to the honey color it had when you first bought it.
In summary, there are three main options for teak patio furniture care. The easiest route is to let your furniture go gray. Just make sure to give it a good cleaning with a teak cleaner on a regular basis so that the color fades evenly and dark patches don’t show up. For those who really want their teak furniture to have a golden color, teak sealer is probably the best option. It provides long lasting protection from UV damage and oxidation that affects the color of teak wood. Teak oil will look great at first, but you’ll soon find yourself regretting the decision to use it since you’ll have to continually reapply oil every few months.
