Our Garden Furniture Oils and varnish offer you high performance and ultra resistance with their advanced formulas specially designed to resist anything thrown at them. The most appealing thing about these products is their ability to offer you superior protection. Whether you want your garden furniture to stop cracking and peeling or you want your outhouse to be protected from the long lasting effects of UV damage, then our flexible range of products are the way to go. Included in this range of products is Osmo Decking Oil, Owatrol Deks Olje Wood Oil, and Teamac Teak Oil, just to name a few. Commercial teak oil is a manufactured product made from tung or linseed oil and resins, and is different from the natural oil found in teak wood.
The products found in this section are extremely ideal for exterior doors, sheds, or woodwork found on boats and yachts. Basically, any wood that is exposed to the elements of everyday for an extended period of time needs the restoration of its natural beauty. By using Promain’s range of Garden Furniture Oils and varnish that we have to offer then you will have perfect results without the worry or colour damage, as all of the products found offer you an enormous amount of nourishment to keep your woods happy and healthy. These products are available in a variety of colours to suit different garden aesthetics. Using the right teak oils can enhance the durability and appearance of both natural and coloured finishes. While teak contains natural oil, the use of commercial teak oil or other wood oils can help maintain the look of weathered or coloured wood.
Wood Protection
Outdoor wooden furniture is a beautiful addition to any garden, but it faces constant challenges from the elements. Sunlight, rain, frost, and humidity can all take their toll, causing wood to fade, crack, or lose its natural colour. Without proper protection, even the highest quality teak garden furniture or hardwood benches can quickly become weathered and dull. That’s why it’s essential to use products specifically formulated to shield your outdoor furniture from UV rays, moisture, and everyday wear. By investing in the right wood oils, stains, or varnishes, you not only preserve the natural beauty of your wooden garden furniture but also extend its lifespan, keeping it looking vibrant and inviting year after year.
Unmatched Quality in Garden Furniture Finishes
At Promain, we provide the right products to restore, protect and maintain outdoor wooden furniture without the fuss. Whether you’re refreshing a greyed-out bench or giving your teak garden furniture a much-needed lift, our garden furniture oils are made to feed and preserve timber while restoring its natural beauty. These oils are also ideal for protecting and restoring exotic wood used in garden furniture.
These treatments are suitable for teak wood, oak, pine, and even more exotic woods. Designed to penetrate the wood surface, they nourish bare wood and revive faded, weathered wood, bringing it closer to its original colour without making it look over-treated or unnatural. They also help maintain and protect stained surfaces, keeping them looking their best.
Hard-Wearing Protection for Outdoor Furniture
British weather is tough on outdoor furniture - between rain, cold winter months, UV rays and mildew, it doesn’t take long for wooden garden furniture to turn grey and worn. Promain’s oils and treatments reduce the need for increased maintenance by offering lasting protection that resists the greying process and protects against water, mould and sun damage.
Whether it’s teak oil, danish oil, or linseed oil, these natural oils are specifically formulated to protect the grain, maintain colour, and reduce weather damage, all while being easy to apply and suitable for most types of hardwood and softwood. While oiling is a common maintenance practice, it is important to consider whether it is necessary for your specific type of wood, as excessive oiling can sometimes lead to increased maintenance or issues such as mold growth or interference with the wood's natural aging process.
More Than Just Garden Furniture
These treatments work not just on garden chairs and tables, but also on sheds, decking, fences, and other timber fixtures. Many customers also use them on outdoor teak furniture, wooden garden gates, and even commercial teak furniture in pubs and outdoor cafés. Certain garden furniture oils are also suitable for use on interior wood surfaces, providing protection and maintaining appearance indoors as well.
If you’ve got timber outdoors that’s exposed to the elements - beech, cedar, oak or teak - these oils and stains are made to keep it looking smart and performing well year-round.
Why Choose Garden Oils Over General Wood Treatments?
General finishes might work inside, but for outdoor wooden furniture, only dedicated exterior wood treatments will last. Products like teak oil and wood stain from Promain sink deep into the wood, keeping it nourished and reducing cracking, splitting, or fading caused by changing temperatures and damp weather.
Outdoor teak furniture, in particular, benefits from specialist treatment that replaces the natural oils lost over time, restoring colour and helping to resist the greying process.
Oil, Stain, or Preserver: What’s Best for Your Timber?
Understanding the difference helps reduce maintenance and get better results:
-
Wood oil like teak or linseed oil nourishes timber from within, leaving the surface looking clean and natural.
-
Wood stain enhances grain visibility while adding protection and colour.
-
Preservers protect against algae, mould, and rot - key for untreated or bare wood.
For garden furniture, three coats of teak oil or danish oil will usually offer more than enough defence. Always apply the first coat to a dry, clean surface. For best results, the wood should be thoroughly wiped with a suitable cleaner or methylated spirit to remove any dirt or residues before oiling or staining. If unsure, test a small, inconspicuous area before applying across larger panels.
Types of Wood Oils
Choosing the right oil for your outdoor wooden furniture can make all the difference in both appearance and durability. Teak oil is a popular choice for outdoor teak furniture and other hardwoods, as it penetrates deeply to nourish the wood and restore its original colour. Linseed oil, derived from flax seeds, is another traditional option that enhances the grain and provides a water-repellent finish, making it ideal for both hardwood and softwood. Danish oil offers a blend of natural oils and resins, delivering a durable, low-sheen finish that’s perfect for garden tables and chairs.
For those seeking a premium solution, high quality tung oil is renowned for its ability to protect exotic woods and create a rich, lasting finish. Each of these wood oils is designed to keep your timber nourished, protected, and resistant to the greying process, ensuring your garden furniture remains a standout feature in your outdoor space.

Restoring Teak and Weathered Wood
Teak naturally contains oils, but constant exposure to rain and UV rays drains it over time. A good quality teak oil replaces this loss and prevents timber from turning grey. If your teak garden furniture has already faded, a quick sand followed by two or three coats of teak oil will restore its appearance.
Allow each coat to dry properly and always wipe off excess oil to avoid tackiness. White spirit can be used for cleaning brushes or thinning oil if needed.
Best Way to Apply Oils to Garden Furniture
Start by cleaning the wood to remove dirt and loose fibres. Make sure the surface is dry before applying. Use a lint-free cloth or brush, and always follow the wood grain. Apply the first coat, wait for it to absorb, then wipe off any residue. Apply a second coat if needed, and a third coat for heavy weather exposure.
Reapply every 6 to 12 months depending on conditions, especially during the winter months when moisture is high.
Treating Softwood Like Pine and Spruce
Softwood garden furniture, especially pine, is more likely to suffer from damp and mildew. Apply a suitable wood preserver early in the wood’s life and follow with either a stain or oil to protect the grain. This approach helps avoid staining, swelling, and rot, especially on horizontal surfaces like bench seats or decking.
Outdoor Protection That Works with British Weather
The key to keeping wood nourished and attractive throughout the year is proper treatment. Combine a preserver with a nourishing wood oil and, if needed, a pigmented topcoat to shield against UV rays and harsh weathering. This three-layer method provides colour, durability, and protection for timber exposed to rain, frost, and direct sunlight.
Preventing Damage to Outdoor Wooden Furniture
Protecting your outdoor wooden furniture from damage starts with regular care and the right products. Applying a suitable wood oil or stain helps to seal the wood surface, making it water repellent and less prone to cracking or splitting. To prevent the onset of mould, algae, or unsightly stains, always keep your furniture clean and free from dirt and debris. During the winter months, consider covering or storing your furniture to shield it from excessive moisture and frost.
Reapplying oils or stains as part of your maintenance routine - especially after periods of heavy rain or intense sunlight - will help maintain the wood’s natural colour and prevent it from turning grey. By following these simple steps, you can ensure your wooden garden furniture stays protected against weather damage, UV rays, and the increased maintenance that comes with neglect.
Year-Round Furniture Care Tips
-
Clean surfaces regularly with mild soap to remove dirt and algae.
-
Inspect timber each season and wipe off standing moisture.
-
Reapply oils and stains every year, or more often for surfaces fully exposed to the sun or rain.
By sticking to a basic maintenance routine, you’ll reduce the need for heavier restoration and keep outdoor wooden furniture looking its best.
Common Issues and Simple Fixes
Varnish or oil going sticky?
Likely applied in damp air or onto an old finish. Sand it back, clean thoroughly, and recoat in dry conditions.
Mould or dark stains on softwood?
Use a mildew remover and clean thoroughly before applying any oil or stain.
Oil not absorbing?
Check if the surface was sealed previously. Light sanding may help, or try thinning the first coat slightly with white spirit.
Stains on oil-finished furniture?
Clean gently with a soft cloth and reapply oil to blend the colour. Always test products in an inconspicuous area first.
