Oil for merbau indoors
For merbau indoors, use Osmo Blanke Was. Merbau is a hard, oil-rich tropical wood, and a well-penetrating oil protects it against moisture and dirt and limits tannin bleed.
Which oil for which merbau surface
Treat a merbau floor or stairs with Blanke Was. Tropical hardwoods sometimes struggle to absorb an ordinary hardwax oil. Blanke Was is made for exactly that: a clear oil that penetrates oily hardwoods such as merbau and wenge more easily. For a merbau tabletop or piece of furniture, choose TopOil, which is food-safe and resistant to coffee, wine and water. On tropical wood, apply TopOil by buffing, in thin coats with a pad or lint-free cloth.
Tannins and stains
Merbau contains substances that can leach out with water and leave brown stains on light surfaces, such as a tiled floor or grout. So treat new merbau thoroughly on all sides before it comes into contact with moisture. A well-penetrating oil makes the surface water-repellent and limits this leaching.
Choose the right sheen level
On dark and tropical woods, a fully matt oil can leave a white haze. Blanke Was is satin matt and therefore a safe choice. Always apply thin coats and buff away excess oil after a few minutes. Test beforehand on an offcut to see how the wood absorbs the oil.
Maintaining oiled merbau
Mop a merbau floor with Wisch-Fix and refresh worn areas with the Vloeibare Onderhoudswas. Keep tables and furniture clean with the Spray-Cleaner. For a merbau bathroom vanity, also use TopOil, buffed on in thin coats; see also treating wood in the bathroom.
