Oil & Maintenance

All timber, even tropical hardwoods, will gradually fade and discolour when exposed to UV sunlight and adverse weather conditions, turning grey and weakening over time.  

To protect your boards from the elements and to keep the colour close to its original state, we recommend cleaning and maintenance at least once or twice a year in the UK.

Wallbarn supplies a range of tried and tested products designed to protect timber and composite materials in the long-term.
