Over time, the weather and UV sunlight can make exterior woodwork look tired and grey. Osmo Wood Reviver Power Gel is a powerful restoring and cleaning agent that will give the wood a new life and bring back a rich fresh look to weathered exterior wood. Osmo Wood Reviver Power Gel has been specially developed to restore the wood back to original colour and character. Easy to apply with a brush, even on vertical structures thanks to the non-drip formula. The deep penetrating effect of the gel is most effective on untreated surfaces with results showing within just 30 minutes. Allow to dry for 48hrs before applying a protective finish. The 2.5L size includes a free Deck Cleaning Brush.
