OLI NATURA® Yacht & Teak Oil

How much OLI NATURA® Yacht & Teak Oil do I need for my surface?

Depending on the container size, OLI NATURA® Yacht & Teak Oil covers the following areas:

For one coat:

• 250 ml: approx. 3–6 m²
• 1 liter: approx. 12–25 m²
• 2.5 liters: approx. 30–62.5 m²

For two coats:

• 250 ml: approx. 1.5–3 m²
• 1 liter: approx. 6–12.5 m²
• 2.5 liters: approx. 15–31 m²

The figures apply to the Natural and Teak variants.

Note: All coverage figures are estimates. Actual coverage depends on the type of wood, final sanding, the wood’s absorbency, and the application method.

Which types of wood and surfaces is OLI NATURA® Yacht & Teak Oil suitable for?

This exterior oil is suitable for untreated, oiled, or freshly sanded outdoor wood, especially teak, Bangkirai, eucalyptus, black locust, and other hardwoods, as well as pressure-treated softwood. Typical applications include decks, garden furniture, pool surrounds, and wooden surfaces on boats.

Does the oil permanently prevent graying?

No. OLI NATURA® Yacht & Teak Oil delays drying out and graying, but cannot permanently prevent natural weathering. How long the protection lasts depends on the type of wood, construction, UV exposure, weather, and use.

How often does oiled outdoor wood need maintenance?

Inspect the surface at least once a year and refresh it once or twice a year, depending on wear. Re-oiling is recommended as soon as the color fades, water soaks in quickly, or the wood looks dry and rough.

Why does treated wood still turn gray or black?

Possible causes include UV radiation, standing water, dirt, algae, fungi, or maintenance intervals that are too long. Poor ventilation and inadequate drainage can also cause discoloration. Thoroughly clean affected surfaces before re-oiling and let them dry completely.

Does the oil protect against mold and mildew stains?

The oil is biocide-free and does not protect against algae or fungi. Infestation can therefore occur on surfaces that remain damp, dirty, or poorly ventilated. Water must be able to drain away freely, and the wood must be able to dry quickly after rain.

Is OLI NATURA® Yacht & Teak Oil waterproof?

No. The oil makes the wood water-repellent but does not create a waterproof seal. Avoid prolonged exposure to moisture, standing water, and use below the waterline.

How should the wood be pre-treated?

The wood must be clean, dry, grease-free, and absorbent. Completely remove any old film-forming coatings. Sand the wood properly and evenly, then remove all dust thoroughly. Clean dirty or grayed surfaces beforehand and allow them to dry completely.

Does new wood also need to be cleaned before oiling?

New wood can also become dirty during storage, transport, or processing. Remove dust, grease, and other residues, and allow the surface to dry completely. For very smooth or planed wood, first check whether it absorbs the oil evenly.

Can I use OLI NATURA® Yacht & Teak Oil on lacquered wood?

No. Old paint and lacquer coatings must be completely removed so the oil can penetrate the wood. Thoroughly clean old open-pore oil finishes and allow them to dry completely.

Can I oil grayed wood or wood with green growth directly?

No. Before oiling, remove graying, algae, moss, and other deposits with a suitable outdoor cleaner. Rinse with clean water, allow the wood to dry completely, and lightly smooth any raised wood fibers if needed.

At what temperatures and in what weather conditions should I apply the oil?

Apply at 15 to 25 °C in dry weather. Do not oil in direct sunlight, extreme heat, high humidity, or when rain is likely. Nighttime dew can also affect drying.

How do I apply OLI NATURA® Yacht & Teak Oil correctly?

Shake or stir the container thoroughly. Apply a thin, even coat of oil along the grain using a brush, deck brush, or roller. After 15 to 30 minutes, remove all excess with a cotton cloth, oil-absorbing cloth, or white pad, and buff the surface. It should feel dry to the touch, not oily.

Why should end grain be treated especially carefully?

End grain, or the ends of the boards, absorbs a lot of moisture. Oil these areas carefully and evenly, without leaving excess product behind. At the same time, make sure water can drain away and the wood can dry again.

Are multiple coats always better?

No. The number of coats depends on the absorbency of the wood. Dense hardwoods like teak usually need only one very thin coat. Severely dried-out or absorbent wood may need a second thin coat after drying overnight.

Why does the surface remain sticky or oily?

Common causes include applying too much, failing to remove excess, a substrate with low absorbency, or residual moisture in the wood. Low temperatures, high humidity, and insufficient air circulation also slow drying.

What can I do if the surface is already sticky?

Wipe off fresh excess with a clean, absorbent cloth and buff the surface dry. Allow oil that has already started to cure to continue curing in a warm, dry, well-ventilated area. If the surface remains sticky, contact OLI-NATURA Customer Service before applying another coat.

How long does OLI NATURA® Yacht & Teak Oil take to dry?

Under suitable conditions, the surface is dust-dry after about one to two hours and fully cured after approximately five days. Low temperatures, high humidity, limited air circulation, or a coat that is too thick will extend drying time.

When can freshly oiled wood get wet again?

Protect freshly oiled wood from rain, water, and damp cleaning for five to eight days. If the surface gets wet too soon, staining, washout, or drying problems may occur.

Why does the color look different on my wood than expected?

The color may look different depending on the type of wood, its natural color, grain, and sanding. Images and on-screen representations are for guidance only. If in doubt, test on the actual wood first. Convenient 20 ml samplers are available for this purpose.

Is the Natural shade really colorless?

Natural contains no pigment, but it is not optically invisible. Like any color-enhancing oil, it deepens the existing wood tone and makes the color and grain appear more pronounced. If in doubt, test on the actual wood first using a 20 ml sampler.

How much color does the Teak shade add?

Teak is lightly pigmented and enhances warm wood tones without changing the wood to an opaque color. On light-colored or highly absorbent woods, the color may appear more intense or reddish. If in doubt, test on the actual wood first using a 20 ml sampler.

Why are there deposits or pigment particles in the container?

Color pigments may settle at the bottom of the container during storage. Stir the oil thoroughly before and during application. If solid particles cannot be mixed in evenly, do not use the product and contact customer service.

How much coverage does OLI NATURA® Yacht & Teak Oil provide?

Depending on the type of wood and its absorbency, consumption is approximately 40 to 80 g/m² or 12 to 25 m² per liter per coat. Rough, very dry, or particularly absorbent wood requires more product.

Can I use the oil on bamboo or WPC?

OLI NATURA® Yacht & Teak Oil is designed for absorbent wood. Bamboo, WPC, and modified materials can absorb oil very differently or not at all. Therefore, follow the material manufacturer’s instructions and, if in doubt, test the product on a small area first. On non-absorbent surfaces, the oil may remain sticky.

Is OLI NATURA® Yacht & Teak Oil also suitable for indoor furniture?

The oil can be used on suitable indoor wood surfaces, but it is specifically designed for exterior wood. For dining tables, countertops, and other indoor furniture, we recommend an interior oil formulated for that purpose.

Does OLI NATURA® Yacht & Teak Oil contain biocides?

No. The oil is biocide-free and contains no chemical film protection against algae or fungi. The Teak variant provides enhanced UV protection through its pigmentation.

Can oil-soaked cloths and pads spontaneously combust?

Yes. OLI NATURA® Yacht & Teak Oil contains drying oils that cure by absorbing oxygen from the air. This generates heat. On the wood surface, the heat can dissipate; in crumpled cloths, pads, or sponges, however, it can build up and cause spontaneous combustion. The product itself is not self-igniting.

Never leave oil-soaked materials crumpled up. After use, store them under water or lay them flat, individually, in a safe place to dry completely. Then dispose of them in accordance with local regulations. Never put oil-soaked materials in a clothes dryer.
