DECKING CLEANING/CARE MAINTENANCE

CARE & SURFACE TREATMENT CARE & SURFACE TREATMENT I enjoy the fresh air, the view of the great outdoors and natural wood.

GOOD TO KNOW: DECKING CARE Timber decking is hard-wearing and easy to maintain – how ever for this it needs a certain amount of care. To maintain and protect decking, it can be treated with specially formulated Decking-Oils from Osmo. Decking-Oils repel dirt and protect the wood; at the same time, they allow the wood to breathe. Maintenance is easy. When necessary, you can re-oil the deck ing without sanding and spot repairs are also possible. >> INITIAL CARE After the correct decking installation and after allowing it to weather off for a certain period of time, the surface can be treated....

CARE & SURFACE TREATMENT NORMAL CHARACTERISTICS OF TIMBER DECKING >> WOOD EXTRACTIVES Wood extractives preserve wood. Depending on the wood species, these could be resin (softwoods), tannin acid (some hardwoods) or other extractives. When these natural extractives leach out, this can be dealt with in various ways. Resin leakage can be removed mechanically or with our Resin Remover Set. Wood species containing tannin acid should not come in contact with metal oxides, otherwise black staining can occur. Wood extractives dissolved by rain should be led away from surrounding building elements...

WEATHERED LOOK ON DECKING CAUSES FOR A WEATHERED LOOK: >> Wood extractives are not weathered off. The wood was saturated; the oils could not penetrate deeply enough and did not bind with the wood from inside. >> Release film on the surface. A release film (e.g. resins and dirt) have prevented the necessary penetration and have strongly reduced the adhesion. >> Excessive moisture absorption. Through improper constructional wood protection (e.g. waterlogging, screw holes within grooves, unprotected cut edges), water is absorbed through capillaries and infiltrates the treated wood. >> Wood...

CARE & SURFACE TREATMENT > INITIAL CARE You have chosen high quality timber decking for good reasons. To enjoy it for a long time, it is important to plan carefully. With timber decking, you can decide whether the surface should develop a natural patina through weathering and only apply a clear finish, or whether the original colour should be preserved with the help of pigmented and colour-matched oils. If you have chosen a pigmented finish, the following should be observed: >> Allow wood species with an especially high content of wood extractives to weather off before the initial...

As top coat on an already colour treated decking, clear oils from Osmo (Teak-Oil, Anti-Slip Decking Oil) enable a less intensive pigmentation. Anti-Slip Decking Oil has a non-slip effect and prevents green growth on the surface. In a single product application, both Teak-Oil and Anti-Slip Decking Oil cannot prevent the natural greying process. > Degrey weathered wood with Osmo Wood Reviver Power Gel before the treatment with Osmo Decking-Oils. > The wood surface must be clean, dry and frost-free (moisture content max. 20%). > The finished surface is influenced by several factors, including...

CARE & SURFACE TREATMENT > REGULAR CLEANING Since surfaces in exposed outdoor areas face more wear and strain, they should be maintained regularly. Dirt and tough stains can be removed with water and Osmo Decking Cleaner. Any damage to the oiled surfaces (e.g. from small rocks) should be thoroughly cleaned and re-oiled. This can be done easily as a spot repair – no sanding required. Thus refreshing the whole area is first necessary after months. >> Osmo Decking Cleaner is a concentrate and can be diluted in ratios from 1: 1 to 1:25 depending on the amount of dirt and stains. >> Use the...

> SPRING CLEANING From time to time, oiled timber decking needs refreshing because Decking-Oils face natural weathering and mechanical wear. Spring cleaning is really simple with Osmo Decking-Oils. Timber decking can be easily cleaned and re-oiled before the greying can begin. Scrub the whole surface thoroughly with a Decking Cleaning Brush and a mixture of water and Osmo Decking Cleaner. Green growth can be removed with Osmo Gard Clean. After thoroughly drying, re-apply one coat of the finish that was last used; whereby unweathered areas with a moderate amount of mechanical strain have to...

> INTENSIVE CLEANING AND REFRESHING Is your timber decking many years old and it still has not been coated? Has it developed a natural grey patina as a result of climatic influences, such as rain and UV radiation? Restoring the natural colour of timber decking is really easy with the especially formulated Osmo Wood Reviver Power-Gel. Simply dampen the whole decking with clear water. Then apply Osmo Wood Reviver Power-Gel generously with Osmo Decking Cleaning Brush. After about 20 minutes, scrub the decking with a hard brush and rinse with a lot of water. This job is even easier with the...

CARE & SURFACE TREATMENT > GREEN GROWTH REMOVAL Because of its location in the garden, surrounding garden plants or just simply too much moisture, your decking has developed a green layer of algae. This green growth is not only unattractive, but also increases the risk of slips and falls; besides that, the algae will eventually destroy the wood. For these reasons, we recommend removing green growth as soon as possible. This is very easy with Osmo Gard Clean. Simply apply – depending on the amount of green growth – either pure or diluted with maximum 10 parts water evenly with a paint brush,...

> LEANING WPC & BPC DECKING C Decking made of polymer composites requires very little maintenance, but it cannot go completely without. Even when installing decking, light “water markings” can be noticed. These are lignin derivatives – discolourations which occur through the reaction of the small content of wood to moisture. These markings, but also other desposits (e.g. from barbecues), can be easily removed with Osmo Polymer Composite Cleaner. Clear the surface of dust and debris with a firm broom or a hand broom. Dilute the concentrate with water, depending of the level of contamination,...
