Product Information

Full details

Osmo UV Protection Oil Extra (1420) is ideal for homeowners and DIY enthusiasts looking to preserve exterior timber surfaces like doors, windows, and garden furniture. Its primary benefit is a microporous, penetrating finish that offers superior UV resistance and weather protection without cracking or peeling, making long-term maintenance significantly easier. Please note that this product provides a clear matt finish, which means it will not change the natural color of the wood but will offer a subtle, low-sheen protective layer.

Extended Product Information

FAQs

Can I apply this over existing paint?

No, you must remove existing paint or varnish layers, as the product needs to penetrate raw wood pores to function correctly.

Is this product suitable for decking?

This specific product is formulated for vertical surfaces like windows and doors. For decking, we recommend using a dedicated Osmo Decking Oil.

How often should I reapply the oil?

This depends on exposure, but typically a fresh maintenance coat is recommended every 2-3 years to ensure continued protection.

Will this product darken the wood?

As a clear finish, it will slightly enhance the natural tone of the wood (similar to the look of wet wood) but will not add pigment.

How do I clean my brushes after use?

Use a specialized brush cleaner like the Osmo Brush Cleaner and Thinner (solvent-based) to remove the oil effectively.

Troubleshooting

The finish looks patchy or uneven.

This is often caused by over-application. Ensure you are applying very thin coats and brushing out the excess oil thoroughly.

The oil is taking too long to dry.

High humidity or low temperatures can slow down curing. Ensure good ventilation and apply thinner coats to speed up the process.

Pros and Cons

Setup, Compatibility & Care

Before applying, ensure the wood is free from dust, dirt, and previous thick coats of paint or varnish. Osmo UV Protection Oil Extra is compatible with most softwoods and hardwoods commonly used in exterior construction.

Stir the product thoroughly before use.
Use a high-quality brush, such as the Osmo Flat Brush, for even application.
Apply a thin, even coat following the direction of the wood grain.
Allow for sufficient drying time (typically 12-24 hours depending on ventilation and humidity) between coats.
For future care, simply clean the surface and apply a fresh thin coat of the oil directly over the old layer—no sanding is necessary.
