Throughout the year, outdoor wood typically works a lot harder than interior wood. Changing weather, temperatures, and wear and tear all add up which gradually deteriorate the natural fibres of wood.
While wood protected with a high performance finish will be durable and longer lasting than unprotected wood, it’s highly recommended to conduct a quick health check to help keep your timber projects looking as beautiful as they were on day 1, and for many years to come.
Let’s explore ways to check your wood today…

What can affect outdoor wood and wood protection?
Every season takes its toll on exterior wood projects, whether that’s fencing, decking, furniture or feature cladding.

The Good News: Easy Maintenance with Osmo
Unlike many film-forming wood finishes on the market, Osmo wood finishes are designed to nourish wood, as well as provide a protective surface coating. Plus, Osmo can be easily maintained without extensive sanding or stripping, before spot repairs or larger future applications.

How To Inspect Exterior Wood
If you answer ‘Yes’ to one or more of the following questions, your exterior wood could benefit from either cleaning, maintenance, an application coat of wood finish, or all of the above.
Does water still bead on the surface?
If water soaks into the timber rather than forming droplets on the surface, the protective finish is likely to have worn away in small or large areas.
Has the colour started fading?
UV exposure naturally lightens or greys timber over time. Cleaning the surface and applying a top up coat will help refresh the appearance of the natural wood or colour wood finish, while restoring its protection.
Does the surface feel dry?
Natural, healthy wood should look and feel nourished, not dry, rough, grey or bleached.
When already working with a colour wood finish, this is often easier to see as the colour may appear patchy and worn.
Is dirt becoming difficult to clean?
As wood protection wears away, water and dirt can penetrate the natural wood surface easily. This leaves marks and stains which can be stubborn to clean. An intact protective finish makes cleaning and maintaining outdoor wood a breeze.
Has mould or algae started appearing?
Damp conditions can encourage mould and algae growth, particularly on decking/horizontal surfaces, shaded areas, and north facing surfaces.
Cleaning the surface and restoring protection can help keep timber looking its best. Often, this is required more frequently than south facing surfaces.
