## Overview

Osmo 420 UV-Protection Oil Extra is a premium 750ml clear satin finish oil designed for vertical exterior wood surfaces. It offers advanced UV protection (factor 12) and water repellency by deeply penetrating the wood grain, preventing greying and degradation. Ideal for cladding, doors, and windows, it enhances natural wood texture with a subtle matte finish. Covering 18m² per liter, it ensures long-lasting durability with easy application and maintenance.

## Description

Protect your exterior wooden surfaces with this specialised UV Protection Oil. Designed specifically for vertically structured wood elements, this clear matt finish oil safeguards against the harsh effects of sun exposure whilst maintaining the natural beauty of your timber. The formula penetrates deeply into the wood grain, providing a water-repellent finish that helps prevent greying and degradation of the wood surface. Perfect for outdoor wooden cladding, doors, windows, and other vertical wooden structures, this oil enhances the natural character of the wood whilst offering reliable protection against UV rays. The matt finish ensures a subtle, natural appearance that won't mask the wood's authentic texture. For optimal results, apply to raw or previously oiled wooden surfaces in dry conditions. Regular maintenance will help preserve the protective qualities and appearance of your wooden surfaces. Directions Surface Preparation Wood surface must be clean, dry and frost-free (moisture content max. 20%). Ideally, surfaces are sanded no finer than a P120 grit grade of sand paper. Sanding to finer grades will reduce required absorbency. Osmo UV-Protection-Oil Exra is ready to use. Do not thin. Stir well using a flat stirring stick or spatula before use. If possible, and if the wood is an absorbent species, please apply the first coat to all sides before installation. Fresh wood containing natural wood ingredients /extractives (eg: Cedar, Larch, Teak, Mahogany or Iroko) are often less absorbent and need to weather off first before applying the product. Please refer to website ‘Suitability’ section for more details. Weathering helps ingredient rich wood become more absorbent and the wood finish adheres optimally. Weathering is also required if ingredient rich wood has been freshly sanded or renovated. A coloured base coat is recommended, e.g. Natural Oil Woodstain. Coloured base coats can improve UV protection. For renovations, clean old microporous wood finishes thoroughly. De-grey any weathered bare wood with Osmo Wood Reviver Power-Gel before applying an Osmo exterior product. Old paints and lacquers must be completely removed. As a general rule, wear a dust mask during sanding works. To maintain absorbency, avoid sanding surfaces finer than a P120 grit. Weather ingredient rich wood after sanding. 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. Soft wood species like Pine or Spruce are more prone to blue stain, rot and insects. If desired, pre-treat these soft woods if possible on all sides with Osmo WR Base Coat. Method of Application With Osmo Flat Brush or Osmo Microfibre Roller, apply thinly along the wood grain and spread well. Allow to dry for approx. 12 hours. Cooler temperatures, higher humidity levels or over application will delay drying. Once dry, apply the second coat thinly. When recoating colour treated surfaces, or for renovation works, one coat applied to the clean and dry surface is usually sufficient. Note Oils enhance and intensify the natural tone of wood (permanent wet effect). Depending on the degree of weathering, apply one coat of Osmo UV-Protection-Oil Extra to the cleaned and intact finish after approx. 3-4 years. Osmo UV-Protection-Oil is best suited to vertical structures whereby there is plenty of water run-off. For areas exposed to strong weathering, such as flat horizontals, weatherboard, post caps or window sills, please expect significantly shorter renovation intervals. Vertical elements mounted onto horizontal wood should have at least a 15 degree angle. Sharp edges must be rounded (radius > 2 mm). If the greying process has already begun, de-grey the surface with Osmo Wood Reviver Power Gel and refinish the dried surface with 2 thin coats of Osmo UV-Protection-Oil Extra. To achieve the UV protection factor 12, it is necessary to apply 2 thin coats of UV-Protection-Oil Extra. With only one coat on untreated wood, the life of the coating is significantly shorter. Using power washers will severely decrease the coverage of the finish and general or multi-purpose cleaners will increase the frequency of maintenance and recoating.

Review: Really great product, super fast shipping. Price was a little on the higher side for the quantity, but if I don't need to re apply every year than it's money well spent! Let's hope I don't need to do it again!
Review: I used this on the exterior of my shed and was very pleased with the results. The shed looks almost new. Easy to apply and dries quickly. Repels rain water. Does darken the appearance of the wood

### ⭐⭐⭐⭐⭐ Review
*by E***N on 17 October 2025*

8 years ago our house was built with an area of Siberian Larch wood cladding on the outer kitchen wall. We wanted to enhance the grain and retain the colour with additional future protection against UV light, weathering and mould, etc. Our builder initially used 2 coats of this product on the wood and recommended we re-treat it with one coat every 2 years in order to retain the wonderful colour and grain effect. As shown in the picture, it still looks as good as new after exposure to 8 years of Scottish weather. It is very easy to apply and dries quite quickly. The 750ml tin is sufficient for at least 3 applications in our case, so very good value for money. I highly recommend this product.
