Maintenance Guide

OUTDOOR SIGNS

Oak doesn’t just look the part — the hardwood’s strength, density and natural resistance to the exterior elements mean it’s a standout exterior performer, too.

UV Radiation

One of the biggest challenges for any outdoor wooden sign is constant exposure to sunlight. Over time, UV rays can fade wood, causing the colours to dull and the natural grain to lose its beauty. In extreme cases, UV exposure can also weaken the wood fibres, making the sign more susceptible to cracking. Using a UV-resistant finish on your sign can help, but regular maintenance will also play a role in keeping it vibrant.

Moisture

Moisture is a wood sign’s worst enemy. Whether from rain, dew, or humidity, water can seep into the wood, leading to swelling, warping, and rot. Signs in particularly wet climates or shaded areas with poor air circulation are especially vulnerable. 

In order to give your sign the best start in life it’s already been treated to 2 coats of Osmo UV Protection oil. This is not only an environmentally friendly finish but it is highly water and dirt resistant too. It’s safe for humans, plants and animals when dry and its microporous, penetrating finish does not crack peel or flake. It delays the natural greying by 12 times in comparison to untreated wood.

Recoating

Your sign should last for a long time, however depending on its location may need a quick top up over time. Simply re-apply one thin coat onto the clean and dry surface when signs of wear become visible.

INDOOR SIGNS (Wood)

Each sign is finished with Osmo Top Oil, a premium, food-safe hardwax oil renowned for its durability and rich finish. This protective coating penetrates deep into the oak, enhancing the natural grain while creating a water-resistant, dirt-repellent surface.

Unlike varnish, Osmo Top Oil allows the wood to breathe, helping prevent cracks and warping over time. The result is a smooth, silky finish that not only looks beautiful but guards your sign for years to come – keeping your treasured keepsake just as striking as the day it arrived.
