Osmo Protects Inside and Out

An extension to a residential property in Buckinghamshire highlights the diverse range of wood finishes from Osmo UK and how these eco-friendly products provide outstanding protection and aesthetically pleasing results both internally and externally.


Built in the 1980’s, this four-bed detached home had a north facing patio, which, due to lack of sunlight was rarely used. With the prospect of a promising summer, the homeowner decided to make the most of the patio area by erecting an extension and extending the kitchen, utilising the unused space.

Jeffrey Powell Associates was the architect for this project and designed an oak framed extension. To ensure the timber would be protected against UV rays, two coats of Osmo UV-Protection-Oil Tints was applied to the frame, door and windows. By absorbing into the oak, the finish allows the surface to remain healthy and elastic, preventing it from drying and becoming brittle. Furthermore, the lightly pigmented UV-Protection-Oil Tints 425 Oak contains an active biocide to help the coating resist algae and fungal attack. As well as protecting the wood, it provided the wood with a tinted stain highlighting the natural wood’s grain, and this complemented the rest of the property.

“We understand that wood can start to look grey and tired if not treated correctly. Despite this, we were still really keen to use the material for the extension but understood it meant that we had to have a high-quality finish applied to protect the material.

“At the same time, we didn’t want the protective layer to detract from the rustic appearance that wood provides. The UV-Protection-Oil Tints ensured all of our requirements were met.”

Protecting the wood internally was just as important on this project. Osmo renowned Polyx®-Oil range was used on the oak frame and on the floor. Polyx®-Oil Effect Raw is a lightly white tinted finish that provides an original, untreated appearance for light coloured wooden surfaces. It not only creates a sought-after look, but also protects the wood’s surface. This finished provided the internal oak beams with a fantastic rustic look. Polyx®-Oil was also applied to the flooring. Providing a water resistant, hardwearing surface. Mud or rainwater that is brought in from the garden, can simply be wiped away.

The extension included a newly kitted out kitchen. The work surfaces were treated with Osmo clear TopOil to accentuate the wood’s natural colours and grains. Resistant to most common kitchen spillages, TopOil provides an easy to clean, and water repellent finish. The new interior doors were treated with Osmo clear Door-Oil. Creating a durable micro-porous finish that is also water-repellent, Door-Oil will not crack, flake or peel. Both the TopOil and Door-Oil products created a pleasing satin finish where applied.

“After having the Osmo UK products applied externally, and being impressed with the quality, we decided that we wanted to stick with its range of products internally as well. The finishes have intensified the original colour and grain of the wood, something which was incredibly important to us.

“Not only are we happy with the finishes at this point, we have been advised that as long as we maintain the surfaces, the finishes will remain in top condition for many years to come.”

Finally, Osmo Wood Wax Finish was applied to all interior skirtings. For optimal protection we applied two coats.

Wood Wax Finish was quick and easy to apply throughout the extension, providing a resistant, durable finish. Designed to add colour to wooden materials, it is great at adding a personal touch to the selected areas in the kitchen.

Offering all the professional features of a traditional oil-based finish, Polyx®-Oil allows the natural texture of the wood to still be apparent. Polyx®-Oil also offers a high level of wear protection that can occasionally be topped up without sanding when required. The finished surface is also spot repairable. Polyx®-Oil’s natural components penetrate deeply into the wood to create a micro-porous finish. This allows the wood to breathe naturally. After treatment, the wood is nourished from within and retains its elasticity. It becomes water repellent, stain resistant and more hard-wearing, because it meets the wood’s natural demands and does not crack, flake, peel or blister.
