Due to their surface properties, ribbed or grooved as well as rough (sawn) wood surfaces absorb more product per square metre than smooth surfaces. 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 Balau: 12 weeks exposure. 006 Bangkirai is optically suitable and a very popular choice of colour tone.

For the following wood types, a weathering period is recommended. Depending on wood species, new or freshly sanded wood requires up to 12 weeks (approximate) exposure to the exterior elements before application. If it doesn't bead, you'll be ready to put on the oil. If it does then you'll have to clean it again until the water stops beading. 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.

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. Rosewood: 4-6 weeks exposure. However, Natural Oil Woodstain 727 Rosewood is optically suitable and requires a weathering period of approx. 12 weeks before use of Natural Oil Woodstain.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. 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. 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.' 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.

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. Colours: The colour swatches are an indication only and representative of the product applied to clean new/pale timber. The final colour finish can vary considerably due to the age, type & condition of the timber being treated. We always recommend carrying out a test area first in an inconspicuous area to make sure you are happy with the final dried colour. If possible, and if the wood is absorbent please apply the first coat to all sides before installation. Ipe: 6-8 weeks exposure. 006 Bangkirai is optically suitable and a very popular choice of colour tone.

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. 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). 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. Coverage: 1 coat up to 8 sq metres/litre of smooth timber and up to 5 sq metres on rough sawn timber, 2 coats recommended.
