• Solvent-borne

Solvent-borne impregnating and drying oil for outdoor use.

Used for surface treatment of new and faded hardwood, heat-treated wood and also for teak, oak and mahogany. The brown hardwood oil restores the original colour of discoloured hardwood. Typical objects are garden furniture, jetties, fences, trellises and doors. Protects the wood from drying, cracking and soiling. Optimum durability is achieved by renewing the WOODEX HARDWOOD OIL treatment yearly. Not suitable for greenhouses, hotbeds or shelters for livestock.
