Can You Apply Teak Sealer over Teak Oil?

Teak is a tropical hardwood harvested mainly in Myanmar, Thailand, and Indonesia. This wood is durable and weathers to a silvery grey color, so it is often used in outdoor construction and furniture. Its durability and moisture resistance make it a popular choice for outdoor furniture for many people.

Types of Finish You Can Use on Teak

The type of finish that you apply to your teak furniture is determined by the type of finish that you want, and the amount of maintenance required. If the teak furniture is used in a wet location or has been damaged in any way, the only way to restore it is to sand and seal it—there are no other options. This can be expensive, so you should be sure that you are looking for teak furniture with a level of protection equal to or greater than what you provide.

1. Stain

Stain provides a natural look to wooden furniture. It is best for furniture that is used in a dry location and does not require frequent maintenance. This type of protection does not stand up well when you have sunlight exposure, so it should only be used if the teak furniture will not be exposed to direct sunlight.

2. Varnish

Varnish provides a glossy look to the furniture. It does not weather as well as a stain but is better for outdoor teak furniture that has to be cleaned often.

3. Oil

Oil provides an extra level of protection for teak furniture. It is applied to the entire piece and is good for furniture that is used in a wet environment.

4. Sealer

The sealer provides the best protection for teak furniture. It is good for furniture that is exposed to direct sunlight and requires frequent maintenance. This is the most often applied type of finish because it provides maximum protection and makes the teak furniture look beautiful.

5. Paint

Paint provides a low level of protection and a high level of maintenance. The only time you would want to paint teak furniture is if you are using it in an inside location, and you are willing to apply frequent coats of paint.

6. Brightener

Brightener provides a cream color to the wood. It does not provide as much protection as oil or varnish, and it is very costly and time-consuming to apply.

Teak Oil vs. Teak Sealer

Teak oil is applied to the entire piece of teak furniture and provides a strong, deep natural color. It penetrates deep into the wood, so you can use it to treat old, damaged furniture. Teak oil looks good for a short time, then it starts to evaporate. Oil is a temporary fix.

The sealer is applied only to the smooth surface of the wood and does not penetrate the wood. It provides a glossy finish that lasts for several years before it needs to be reapplied. Sealer is applied by professionals and can involve sanding down the teak furniture first, then sealing. It provides a layer of ultraviolet (UV) protection to teak wood which is important for outdoor furniture.

How to Apply Teak Sealer

Teak sealer is a finishing product applied to the surface of the furniture. The manufacturer sells it in ¼ and ½ ounces, 1-ounce, and 2-ounce bottles. You might have only one coat of sealer on your teak furniture or several coats of sealer. Here is a basic guide to applying a sealer, but you should always follow the instructions on your bottle.

1. Sand or Scuff

Teak wood is naturally smooth and solid, so you may need to sand down the entire piece before applying a finish over it. The sanding removes any loose particles or spider webbing that might cling to the surface, and it prepares the surface for a finish. If you are working with a piece that has been sealed with varnish, sand it first to remove any varnish residue.

2. Apply Teak Oil

After sanding, apply the teak oil in a thin coat and allow it to dry. The oil helps protect the wood from water and sunlight.

3. Apply Teak Sealer

The sealer creates a shiny, smooth surface that is characteristic of teak furniture. After you have sanded to remove any rough patches, apply a thin coat of teak oil, then immediately follow with the sealer. The teak oil adheres to the wood and allows the sealer to stick firmly to it.

Where to Use Teak Sealer?

Teak sealer is an important addition to your teak furniture. If you want to maintain the natural look of the teak furniture, and if you are going to be using it in a dry environment, then you should use oil. If you want the teak furniture to look great and last for decades, then you must use a sealer. You can apply sealer on outdoor or indoor teak furniture, but outdoor teak furniture will need extra protection.

1. Outdoor Teak Furniture

Because teak is vulnerable to water and sunlight, you should apply oil over it before applying stain or varnish. This helps prevent the wood from drying out too quickly and allows the finish to penetrate the wood more easily. You should apply an extra coat of oil after applying the sealer to make sure that it doesn’t dry out too quickly.

2. For Protecting Hardwood

Kitchen cabinets, bathroom cabinets, and other wood furniture need a layer of oil or varnish to protect them from water and sunlight. Applying sealer over the wood increases its protection. A sealer is less expensive than oil or varnish for covering a large area, so you should use a sealer for protecting your hardwood.

3. For Protecting Marine Wood

Marine wood, like teak, is vulnerable to sunlight and water. For maximum protection, use a varnish over marine wood before using a sealer.

Is Teak Oil Okay for Food-grade Surfaces?

The sealer and oil that you apply to your teak furniture are used to protect it from sunlight, water, and heat. The material used in the construction of kitchen cabinets, bathroom cabinets, and other wood furniture can be affected by these elements. If you are using teak oil to protect the wood of your wooden furniture, then be aware that it contains polychlorinated biphenyls (PCBs) that can leach into food when the wood is cut or damaged.

1. Wood and Water

The teak wood that comes into contact with water or moisture can begin to warp and crack. Exposing the wood to water for long periods can cause it to swell or swell, which can cause the wood to crack. If you have teak wood furniture in a wet location, then you should apply a coat of oil over it every year or so to protect it from water.

2. Sealing the Wood of Your Furniture

You should not just apply a sealer to the surface of your teak furniture. You can use it on its own, or you can apply it over oil. Teak wood is prone to absorbing liquids, so you should seal the wood if you are using it for food-grade surfaces. If you have a piece of teak wood furniture in a wet environment, you may want to consider sealing it before using it in that location.

3. Fungus or Mold

If you have a kitchen cabinet that has been stained, and after a few months the wood starts to turn orange, then you may have a problem with mold or fungus. This can happen if the surface of the wood has absorbed moisture and then turned moldy. If you want to prevent this from happening in your teak furniture, then treat it with oil first before applying a sealer over it.

4. Use Pure Oil

Never use oil on kitchen cabinets that are for food use. Purchase oil that is specifically for sealing the wood, and use it to treat your teak furniture. If you want to apply a sealer over your teak furniture, then choose a sealer that has a paint-like consistency, but warns against using it near food.

5. Protect the Color

If you are applying a sealer over your teak furniture, then you should consider treating the surface with oil first. Sealing the surface helps protect the color of the teak wood and keeps there from any blemishes on it.

6. Teak Oil and Sealing Teak Wood

After applying all of the necessary steps, you should consider oiling your teak furniture before applying a sealer over it. You must coat the wood before sealing it because both sealers and oils contain polymers that reduce or eliminate the protection of teak oil or varnish. You will want to use oil on your teak furniture, then apply a sealer over that oil to add an extra layer of protection.

Conclusion

Teak is a beautiful material that has been used in furniture for hundreds of years. It is very durable and can provide beauty and longevity to your home. Even though you can apply oil or varnish to your teak furniture, you should probably use the best teak sealer available, because it provides better protection for both the wood and its finish.

It is important to follow all the instructions and directions on the label. Only a professional can tell you if the wood has been properly sealed or not, so it is best to have someone check your teak furniture before it becomes a serious problem.
