The OLI-NATURA Hardener is the B component for selected 2K oils and enables significantly faster curing, greater resistance, and optimal oil bonding. Through additional molecular cross-linking, deeply anchored, closely cross-linked oil structures are formed, making the surface particularly robust and durable.

Thanks to its VOC-free formula (0% solvents), the hardener is environmentally friendly and safe to use. It improves chemical resistance and optimizes pigment absorption in coloured oils. Especially with a very fine final sanding, it ensures that the oil penetrates deeply into the wood fibres even with high grits.

Application with OLI-NATURA Hardener is particularly recommended for heavily used surfaces such as floors, stairs, and worktops, as well as for wet rooms and wood and epoxy resin projects with very fine sanding - ideal wherever quick use of the surface is required.

Note: This product contains less than 0.1% diisocyanate monomers and may therefore be used without additional training.

Mixing & Application

  • Mix the hardener thoroughly with the oil in the specified ratio shortly before use
  • Process the material immediately - do not pour it back!

Pot life & application

  • Pot life: The processing time is approx. 2–3 hours

Which oils can I use with the hardener, and what is the mixing ratio?

The OLI-NATURA Hardener is suitable for selected 2K oils from OLI-NATURA :

5:1Worktop-Oil, 2K Colour Oil, HS Professional Oil coloured
10:1HS Professional Oil, HS Professional Oil coloured

Important: Use within 2–3 hours.

Can I store oil already mixed with hardener?

No. After mixing, the chemical reaction begins, and the mixture should be applied within the pot life. After that, it is no longer usable.

Can I still use the oil-hardener mixture after the pot life?

No. After 2–3 hours the viscosity increases, meaning the oil can no longer be processed optimally. Therefore, only mix the amount needed!

What are the benefits of adding OLI-NATURA Hardener?

Faster curing – reduces drying time
Higher resistance – improved chemical resistance
Optimized pigment absorption – particularly advantageous for coloured oils
Better oil cross-linking with very fine sanding – ideal for wood and epoxy resin surfaces

How long can OLI-NATURA Hardener be stored?

Approx. 6 months in the original packaging and in a dry, tightly sealed storage location.

Can I continue using opened hardener?

Yes, as long as it remains airtight.

Tip: Clean the pourer immediately with a clothto prevent the closure from sticking .
