Osmo Wood Reviver Power Gel for Greyed Decks & Exterior Wood
Osmo Wood Reviver Power Gel is a thick, non-drip cleaning gel that removes the grey weathered layer from exterior wood. You brush it on, wait, scrub and rinse. It clings to vertical surfaces, so it suits cladding and fences as well as decks. Re-oil the wood afterwards.
Key Features
- Non-drip gel that stays put on vertical surfaces.
- Removes grey patina from weathered exterior wood so a fresh finish can go on.
- Ready to use. Don't thin it. No mixing.
- Contains biodegradable oxalic acid (under 5%). Free of solvents, formaldehyde, chlorine compounds and amines.
- Coverage: about 10 m² per litre (110 sq ft) per application.
Where to Use It
Greyed decking, terraces, timber cladding, fences and garden furniture. Exterior wood only. It cleans but does not protect, so oil the wood afterwards.
Reviver Gel or a Finish?
The gel is a prep step. After it dries for about 48 hours, protect the wood. For decks use Osmo Decking Oil. For vertical wood such as siding and fences use Osmo UV-Protection Oil.

FAQ
1How much Wood Reviver do I need for a deck?
Coverage is about 110 sq ft per litre per application. A 12 x 16 ft deck is 192 sq ft, so one application takes about 1.75 L. Add more for rough wood, steps and railings.
2What does it do, and what doesn't it do?
It removes grey patina and dirt from exterior wood. It does not protect the wood. Apply an oil finish after it dries.
3What should I use after it?
Wait about 48 hours, then finish. For decks, use Osmo Decking Oil. For vertical wood, use Osmo UV-Protection Oil.

No. Osmo makes it for greyed exterior wood: decking, terraces, cladding and garden furniture.
