The finished surface is influenced by several factors, including the condition of the wood. Therefore, a trial application is always required, especially for unfamiliar surfaces.

Not to mention that it replenishes some of the natural wood oils that have been lost due to a variety of factors. Many wood species contain water-soluble coloured extractives ( eg Larch ) which may leach out naturally when weathered. Weathered, bare wood surfaces can be refreshed with Osmo Wood Reviver Power-gel.

Alternative decking treatments

Bangkirai: 12 weeks exposure. 006 Bangkirai is optically suitable and a very popular choice of colour tone. It’s designed to penetrate deep into the wood to replace the natural oils lost over time through weathering, and to offer deep-seated protection against splitting and drying, while the tinted oil brings out the colour in greyed wood for a fresh look. Thoroughly clean or lightly sand old microporous stains or completely remove old varnishes before application. If any sanding works are carried out some fresh wood species must be weathered as directed above to improve absorbency once more. Sanding to finishing grades of no more than a P120 grit are recommended. Always wear a dust mask when sanding. Balau: 12 weeks exposure. 006 Bangkirai is optically suitable and a very popular choice of colour tone. We recommend using the clear version, as it delivers a beautifully natural finish. The same can't quite be said about the teak colour, as it's a little orange.

Bare wood species with a high content of natural wood extractives need to weather off (min. 4 weeks) before the initial treatment or be cleaned with Osmo Brush Cleaner and Thinner (degreaser). Oils often come in natural colours or clear, and enhance the natural appearance of your wood,' explains Jimmy Englezos, senior product manager at Sherwin-Williams. Due to their surface properties, ribbed or grooved as well as rough (sawn) wood surfaces absorb more product per square metre than smooth surfaces. Staining can provide more colour options than oiling, but it can be more difficult to maintain and may require more frequent refinishing. However, oiling is often easier to maintain and when using a clear finish will offer a more natural look. In addition, oiling may not provide as much colour variety in comparison to staining. Oil is also really durable and is easy to maintain – you just need to keep it clean and touch it up every now and then. It’s very resistant to dirt and water so doesn’t require much upkeep at all.'We also deliver to the majority of non mainland UK locations including The scottish Highlands & islands, Isle of Man, Isle of Wight, Isles of Scilly and Northern Ireland. Please see full delivery terms for the extra charges associated with these locations For the best protection, apply an exterior wood preservative to protect against mould, algae, dry rot, woodworm and wood related diseases Resinous wood, such as Larch or Douglas Fir, needs to weather off for at least 6 weeks to improve absorbency. Pressure impregnated wood and tropical species like Massaranduba, Bangkirai, Garapa, Iroko need to weather off for at least 3 months. Cedar requires a 3 month weathering period to improve absorbency. Ipe: 6-8 weeks exposure. 006 Bangkirai is optically suitable and a very popular choice of colour tone.
