Osmo UV 410 is a high quality oil that protects against the greying effect of the Sun's UV rays by a factor of 12. Dries to a satin matt finish.
Easy to apply with a brush or velour roller. The 410 will not peel or flake, and is child-safe once dry. This product is NOT recommended for floors, instead use Osmo Polyx Oil.
For UV protection with fungicide we recommend Osmo UV Protection Oil Extra.
Please be advised that 125ml tins are printed in German only. For application instructions refer to the overview below.
Osmo UV-Protection-Oil 410 offers a satin-matt, clear finish for exterior wood. It is based on natural oils and does not crack, flake, peel or blister. Osmo UV-Protection-Oil 410 prolongs the renovation time significantly with a UV-Protection factor of 12 in comparison to untreated wood. Easy to apply and renew, no sanding or primer necessary.
Wooden surfaces must be clean, dry and frost-free (maximum moisture content 20%). Osmo UV-Protection-Oil is ready to use straight from the tin and doesn't require thinning. Stir well before use.
Clean existing oil finishes thoroughly. Any previous traces of varnish must be removed completely. Surfaces should not be sanded finer than 120 grit.
If additional protection against blue stain, rot and mildew is required for outdoors pre-treat with Osmo WR Base Coat 4005.
Please Note: Osmo WR Base Coat 4005 does not contain an insecticide so will not protect the wood from wood worm or other wood boring insects. For complete protection against mould, algae, dry rot, woodworm and other wood boring insects, consider Barrettine Premier Wood Preservative or Ronseal Total Wood Preservative. If using either of these products, please allow a full 24 to 48 hours drying time before applying Osmo UV Protection oil 410.
Wooden surfaces that have turned grey / silver over time can first be treated with Osmo Wood Reviver Gel 6609 to restore the colour of the wood prior to coating with Osmo UV Protection Oil 410 or wood preservative.
Apply thinly and evenly along the wood grain with either a good quality paint brush or Microfibre Roller, working the oil in to the surface of the wood. Allow for good ventilation whilst drying. Apply a second coat as before
Make sure that the surface is clean and dry prior to application. The finish is among other things influenced by the wood's natural characteristics, therefore a trial application is required before finishing.
Depending on the level of weathering apply 1 to 2 coats of Osmo UV Protection Oil 410 approximately every 2 to 3 years on cleaned and intact wooden surfaces.
A shorter renovation period may be required if wooden surfaces are exposed to extreme weathering. This may also apply to horizontal surfaces where water cannot drain.
If the surface becomes scuffed, scratched or marked, simply rub the effected area with a scotch pad then re-apply a coating of the 410 exterior wood oil to the damaged area.
To clean brushes use Osmo Brush Cleaner and Thinner 8000. To remove excess oil or spillages use white spirit.
Shelf-life is up to 5 years or more if product is correctly stored. If thickened by frost, it will regain its consistency under normal temperatures within 24 to 36 hours.
To maximise the life of any left-over oil, decant into a container bottle or jar with an air-tight lid. Fill the container to the rim minimising the amount of air in the container and secure the lid. Store in a location where the product is unlikely to freeze or overheat such as an under-stairs cupboard.
Warning: Wash out any used cloth impregnated with this product immediately after use or store in an airtight container (danger of self-ignition).
Q. It states in the Osmo leaflet that this product is for exterior use. Can it be used on the interior of a real wood conservatory as it gets full sun for much of the day and i would like to protect the colour of the timber.
A. Osmo UV protection Oil 410 is classed by Osmo as an exterior product. This said however, we receive lots of positive feedback from customers who have used Osmo 410 on interior wooden surfaces such as window frames, sills and wooden conservatories.
Q. Can Osmo UV protection Oil 410 be used on conservatory or kitchen floors that are subjected to direct sunlight?.
A. The product advice from Osmo is that this product is not suitable for use on horizontal surfaces such as floors as it doesn't have the same durability as their interior Polyx Oil products. This said however, we are aware that some customers have used Osmo 410 on flooring then applied a coat of Polyx Oil over the top for added durability.
approximately 12 hours (normal climatic conditions, 23℃ /50%, normal humidity). Lower temperatures and/or high humidity can increase the drying time.
