refreshes the natural color and protects the wood from within.
"Do I even need to oil teak wood?"
Teak is naturally oily and protects itself – so it doesn't necessarily have to be oiled. Over time, however, lignin in the wood degrades due to UV and rain, creating a silver-gray patina. This is a natural process, but it's not visually appealing to everyone. If you want to preserve the original wood color, you should regularly re-oil with OLI-NATURA Yacht & Teak Oil – it freshens the color, protects against graying, and cares for the surface.
"How do I know when to re-oil and how often?"
If the surface appears rough or grayed, it's time for re-oiling – especially if the silver-gray patina is to be avoided. The frequency depends on the weather: outdoor furniture needs more care, protected furniture less. As a rule of thumb: oil 1–2 times a year, preferably in spring and autumn.
"Can I oil over old paint?"
Unfortunately, no. If there is still varnish or a thick-layer glaze, it must be completely removed. Oil needs open pores; otherwise, it won't penetrate the wood, won't protect from within, and will remain on top as a sticky film.
"Do I need to sand before re-oiling?"
No – if the wood is already naturally oiled and not severely grayed, it's enough to clean it thoroughly and then re-oil. Sanding is only necessary for old varnishes, glazes, or severe gray haze.

Simply pour into a bowl – this allows for easy dosing of the teak oil.
Apply thinly and evenly in the direction of the grain – remove excess after 15–20 minutes.
"How do I apply the oil correctly?"
It is best to apply thinly and evenly with a brush, roller, or pad in the direction of the grain. Important: Remove excess oil after 15–20 minutes with a lint-free cloth to prevent sticky spots from over-oiling. If necessary, the application can be repeated the next day.
"How do I properly prepare my wood for oiling?"
First, clean thoroughly with a brush and mild exterior cleaner and let the wood dry well. Smooth raised fibers with a sanding sponge and dust off the surface. A high-pressure cleaner is also possible, but only carefully: low pressure, flat jet, maintain distance, and work in the direction of the grain. This works well with hardwoods like teak, Bangkirai, or Douglas fir. If the surface is grayed, a wood degrayer helps; for deeper graying, stains, or rough wood, sanding is the best solution.

"Does the Yacht & Teak Oil in Teak color also work on other woods?"
Of course! The pigments are so subtle that they don't artificially recolor acacia, eucalyptus, robinia, Bangkirai, Douglas fir, larch, garapa, or cumaru to "teak." They merely accentuate the natural color and highlight the grain. Another advantage: the slight color content provides extra UV protection and slows down graying.
"Why do I sometimes need more or less oil than specified?"
Because every type of wood absorbs differently – and it also makes a difference whether you are oiling for the first time or re-oiling, and how heavily the wood has been used. A leached surface stressed by sun and rain absorbs significantly more oil than a new surface. A rough guideline is 40–80 g per square meter per application.
"How do I deal with oil-soaked rags?"
When oxidatively drying oils, heat is generated – in crumpled, oil-soaked rags, it cannot escape, which can lead to spontaneous combustion in unfavorable cases. Therefore, never leave them lying around carelessly! It is best to immediately moisten the rags with water, let them dry spread out outdoors, and then dispose of them.
