What are the benefits of OLI NATURA® Hardener?
OLI NATURA® Hardener supports curing through additional cross-linking, accelerates curing, and increases the chemical resistance of the treated surface. For approved colour oils, it supports pigment integration. It is also suitable for applications with a fine final sanding.
Which oils can I use with OLI NATURA® Hardener?
OLI NATURA® Hardener is approved for use with the following oils. The mixing ratios apply by volume, oil : hardener.
5:1
- OLI NATURA® Worktop-Oil
- OLI NATURA® Colour-Oil Midnight-Black
10:1
- OLI NATURA® HS hardwax oil colourless
- OLI NATURA® HS Professional Oil colourless
- OLI NATURA® Colour HS Professional Oil
Is OLI NATURA® Hardener a thinner?
No. OLI NATURA® Hardener is a reactive hardener component. It supports the cross-linking and curing of the oil and does not replace an oil thinner.
Can I mix the oil and hardener directly on the wood surface?
No. Before application, mix OLI NATURA® Hardener thoroughly with the oil in the specified ratio. Only prepare the amount required.
How long can I use the mixed oil?
After adding OLI NATURA® Hardener, the pot life for colourless oils is 2–3 hoursand for coloured oils a maximum of 2 hours. Do not continue using the mixture after the pot life has expired.
Can I store the oil-hardener mixture?
No. Mixing in OLI NATURA® Hardener starts the reaction. Use the mixture within the pot life and do not pour it back into the original container.
What do I need to bear in mind with oil-soaked cloths and pads?
Risk of spontaneous combustion: After use, completely soak cloths and pads saturated with oil or an oil-hardener mixture in water and allow them to dry outdoors, spread out individually on a non-combustible surface.
