Osmo Oil Stain Hardener is a hardener which may be added to a 1 litre can of Osmo Oil Stain, where accelerated drying is required – such as for commercial areas such as shops, cafes and restaurants etc. It is also recommended when staining timbers with high resin and oil content such as Matai, Totara and Mahogany etc.
Addition of the Hardener shortens the drying time of the oil stain from 12 hours to just 4 hours, which means one coat of stain and one top coat can be applied in one day.
Add the contents of a 60ml bottle of Hardener to a 1 litre can of Oil Stain, and stir thoroughly. Pot time is approximately 60 minutes.
Osmo Hardener is only suitable for use in OSMO Oil Stain. It is not suitable for use in other OSMO products. It is a professional use product only.
Osmo Hardener for Oil Stain is a flammable liquid. It contains isocyanates, which may cause serious health issues if inhaled or swallowed. Safety details are printed on the can’s label, and an MSDS can be downloaded from this page.
