HS Professional Oil: Wood oil with a long open time for professionals
Anyone who oils wood surfaces square meter by square meter knows: the clock starts ticking after application - because the so-called “open time” is limited. As soon as the wood oil starts to set, the surface can no longer be properly worked over or polished. Many wood oils dry too quickly - a real challenge on large areas such as parquet floors, especially when working alone on site.
Long open time - ideal for large areas
The OLI-NATURA HS Professional Oil is a professional wood oil for floors, stairs and furniture with an extra-long open time of up to 60 minutes. It adapts to the realities of professional work and gives parquet installers, stair builders and carpenters the application reliability they need.
After application, there is enough time to carefully work in and polish the wood oil without time pressure - even on large areas or many consecutive stair treads.
One application is enough - thanks to high-solid technology
The HS Professional Oil is solvent-free, highly productive and in many cases a single application is sufficient for complete impregnation - because nothing evaporates that would subsequently need to be replaced. The oiled surface can be used again after just 12 to 24 hours and is fully cured after about one week.
The protection can be refreshed at any time by re-oiling, and repairs are easily possible.
An oil that adapts to professional work
High-solid. One application. Perfect results.
A wood oil for professionals that adapts to the daily demands of the trade - with a long open time, quick return to use and a versatile range of applications.

🔍 What does “open time” mean?
The open time refers to the period after application during which the wood oil is still fluid and workable - meaning it can be spread, worked over or excess material removed without risking streaks, spots or drying marks. With OLI-NATURA HS Professional Oil, it is up to 60 minutes - depending on temperature, humidity, air movement, type of wood and quantity applied.
