Outside · Terraces & Decking
A deck that ages with the weather, not against it.
Walkable timber out in full sun and rain — sealed from the inside with a penetrating oil that you re-oil in place, never strip and refilm. Here is the system we specify for wooden decks and terrace boards.
- Decks
- Terrace boards
- Boardwalks
- Tropical hardwood
The recommended system.
One penetrating oil for the deck — Terrace Wood Oil 236, or Teak Oil 223 for teak and oily hardwoods — no separate primer, with Anti-Greying Fluid 940 to strip the grey first if the boards have weathered.
For wooden decks and terrace boards, this is the system we specify — the oil, and the way you renew it. Pick one oil to match your timber; the oils need no primer.
A deck has no separate care product — it renews by re-oiling, in place, with the same oil you finished it with. Which path you take depends on the state of the boards: a sound deck is simply re-oiled; a deck that has greyed in the sun has to have the grey stripped back first, or fresh oil just sits on dead, silvered fibres.

specifies penetrating oils for walkable decks — never a film. Terrace Wood Oil 236 and Teak Oil 223 harden inside the boards and renew in place; a film varnish on horizontal, weather-soaked timber peels and traps water, which is why we keep it off your deck.
Why it’s demanding
What an open deck puts a finish through
Sun & greying
Flat boards take direct UV all day — and an unprotected, untinted finish silvers and greys within seasons.
Rain & damp
Water pools on a horizontal deck instead of running off — a film traps it and rots the wood beneath.
Walked on, dragged over
Bare feet, furniture and constant traffic work the boards — the finish has to renew in place, never peel.
A deck is renewed, never refilmed.
A varnish on a flat, weather-soaked board cracks, lifts and traps water until the whole deck has to be sanded back. A penetrating oil hardens inside the fibres instead — when it weathers you clean the boards and re-oil them in place, the same oil you started with.

Questions about terraces & decking
Quick answers on formulation, application and Indian-climate suitability. Pulled from our full FAQ and TDS library.
- No. Terrace Wood Oil 236 and Teak Oil 223 are self-priming penetrating oils — the first coat does the priming, soaking into the fibres rather than building a film on top. There is no separate primer for an oiled deck. Make sure the boards are bare, clean and dry, then oil directly.
- Both name wooden terraces and decks in their TDS, so either protects a deck. Reach for Teak Oil 223 on dense, oily tropical hardwoods like teak and bangkirai, which it is made especially for; Terrace Wood Oil 236 is the oil-resin finish designed for terraces and decking in general — oak, softwood and thermo-wood. If you are unsure of your timber, talk to us before you order.
- Not directly — fresh oil sits on top of dead, silvered fibres and will not hold. Strip the grey first with Anti-Greying Fluid 940: brush it on, let it react, scrub and rinse, then allow 1–2 days to dry and sand lightly. 940 gives no protection on its own, so once the warm tone is back and the boards are dry, re-oil with 236 (or 223 for teak and bangkirai).
- For full Indian sun we steer you to a pigmented oil rather than a colourless one. The mineral pigments are what shield the wood from UV, so a tinted finish resists the greying that a clear oil cannot hold off. A colourless variant offers far less UV protection on an exposed, horizontal deck.
- No — new CCA pressure-treated timber needs to weather outdoors for 1–2 months before its first oil, so the surface is ready to accept the finish. Any timber that has greyed or weathered must be sanded back or pre-treated with Anti-Greying Fluid 940 before you oil it.
