OLI-NATURA HS Härter is a high-solid hardener additive designed to be mixed with OLI-NATURA HS Professional Oil and OLI-NATURA Worktop Oil. Added at 10%, it accelerates curing while significantly improving chemical and mechanical resistance, making it well suited to demanding interior timber surfaces.

  • Designed specifically for use with HS Professional Oil and Worktop Oil

  • Speeds up through-curing, reducing time to serviceability

  • Improves chemical resistance against household liquids and spills

  • Increases mechanical durability for higher wear areas

  • Helps achieve reliable curing even in challenging conditions, including higher humidity

  • Supports single-coat systems where appropriate, improving efficiency

  • Ideal for benchtops, tables, joinery, and interior timber surfaces requiring added resilience

OLI NATURA Hardener is a solvent-free hardener additive designed for use with HS Professional Oil and Worktop Oil. It is added to the oil prior to application to speed up curing and improve resistance to chemicals and everyday wear.

This additive is used when faster hardening is required, or where additional surface resistance is beneficial—such as kitchens, benchtops, and high-use timber surfaces.
