Oil can do more. From protection to design.
The HOLZ-HANDWERK 2026 showed: Oil has developed from a mere protective agent into a targeted tool for designing appearance and feel - with clearly recognizable effects, from light raw wood looks to dark surfaces inspired by charred wood.
The most important oil effects at a glance

raw wood effect (Invisible / Raw Wood Oil)

Off-White effect

Unlike the classic lime effect, slightly muted whites such as Cotton White (Colour hardwax oil) or Light Ivory (Colour HS Professional Oil) appear calmer and more homogeneous. The structure remains visible but hardly stands out in contrast.
Natural tone effect

The wood is oiled and intentionally enhanced. The surface appears warm, lively, and deep. Honey-colored to golden oak tones and natural shades of brown are in demand - a deliberate move away from cool gray tones. Typically achieved with OLI-NATURA HS Professional Oil in Natural and Colour.
Black effect

The wood is treated with black oil, for example with OLI-NATURA 2C Colour Oil Midnight Black. The grain remains visible and tangible, while creating a dark, elegant to industrial look. In combination with reactive pretreatment stains, the effect can be deliberately developed into a carbonized surface inspired by charred wood.
Smoking effect

The smoking effect recreates the classic smoking process. Reactive stains such as the VOC-free OLI-NATURA Antique reactive stain react with the tannins in oak or walnut and produce deep brown to gray-brown shades. The surface is then oiled.
Bicolor effect

Structured surfaces are built up in two colors. A colored primer, for example in white or gray, remains in the pores, while the surface is subsequently treated with a contrasting oil, such as black - for greater depth and clarity. Typically achieved with OLI-NATURA Colour hardwax oil.
What matters today
Natural feel. Matte appearance. Sustainability. Repairability.
Processing efficiency is also crucial today. Modern high-solid oils produce a finished result in just one application - instead of two or three. Systems such as OLI-NATURA HS Professional Oil represent this one-layer approach and can be processed flexibly with or without hardener (10:1), depending on the application.
The color focus is also shifting: away from gray toward warm, natural shades of brown - complemented by selectively used dark, semitransparent black tones.
